Indawo yokugcina amandla ebhetri isebenza ngokutshaja iibhetri ngamaxesha ombane ophantsi kakhulu okanye ukuveliswa okuphezulu okuvuselelekayo, ukugcina loo mandla njengekhemikhali, kwaye iwakhuphele kwakhona kwigridi xa imfuno ephezulu okanye imithombo ehlaziyekayo ingekho. Le ntlawulo-yevenkile{2}}yomjikelo wokukhupha ilawulwa ziinkqubo zolawulo eziphucukileyo ezibeka iliso kwimpilo yebhetri, ephucula ukusebenza kakuhle, kunye nokulungelelaniswa nabaqhubi begridi ngexesha lokwenyani. Ukuqonda indlela indawo yokugcina amandla ebhetri esebenza ngayo ifuna ukuvavanya zombini iinxalenye zayo zomzimba kunye neenkqubo zesoftware ezikrelekrele eziququzelela izigidi zezigqibo suku ngalunye.
IZithathu -zoYilo loYilo lweBESS Operation
Ukuqonda indlela indawo yokugcina amandla ebhetri isebenza ngayo kufuna ukujonga iileya ezisebenzayo ezintathu ezahlukeneyo kodwa ezidibeneyo. Umaleko ngamnye uphatha imisebenzi ethile, ukusuka kulawulo lweeseli zebhetri ukuya ekuphumezeni iinkonzo zegridi ezintsonkothileyo ezixabisa izigidi ngengeniso.
Umaleko woMzimbaiphatha ukugcinwa kwamandla kunye nolawulo lwe-thermal. Amawakawaka eeseli ze-lithium -ze-ion{2}}ngokuqhelekileyo i-lithium iron phosphate (LFP) okanye i-nickel manganese cobalt (NMC) chemistry{3}}zicwangciswe ngokwemodyuli, iiracks, kunye nezikhongozeli. Ezi seli ziguqula amandla ombane zibe amandla ekhemikhali ngexesha lokutshaja kunye nokuguqula inkqubo ngexesha lokukhutshwa. Ukubaleka ngokuqhubekayo ecaleni kwenkqubo yolawulo lwe-thermal, usebenzisa ukupholisa ulwelo okanye i-HVAC ukugcina ubushushu bokusebenza obuphezulu phakathi kwe-15-35 degree. Ngaphandle kokupholisa okufanelekileyo, iiseli zinokungena kwi-thermal runaway, apho ubushushu bangaphakathi bukhuphuka bubangela ukusabela okuyingozi kwekhonkco.
Intelligence Layerilungelelanisa yonke imisebenzi yenkqubo. Inkqubo yoLawulo lweBattery ijonga amandla ombane, angoku, ubushushu, kunye nemo yentlawulo yeseli nganye, ithatha izigqibo ze-microsecond ukulungelelanisa iiseli kunye nokuthintela umonakalo. Inkqubo yoGuqulo lwaMandla iguqula amandla eDC ukusuka kwibhetri ukuya kwigridi{2}}amandla e-AC ahambelanayo kwaye iphatha umva ngexesha lokutshaja. I-Energy Management System ihleli ngaphezu kwazo zombini, ithatha isigqibo sokuba ihlawuliswe nini okanye ikhutshwe nini ngokusekelwe kwiimeko zegridi, amaxabiso ombane, kunye noqikelelo lwemozulu. Iziko eliqhelekileyo le-100MW liqhuba izigidi zamanqaku edatha ngomzuzwana kuzo zonke ezi nkqubo.
Uluhlu lweSiceloihambisa ixabiso kubasebenzisi begridi kunye nabanini beziko. Ukuphendula ngokukhawuleza kwefrikhwensi igcina i-frequency yegridi ngokuthe ngqo kwi-60Hz (i-50Hz eYurophu) ngokutofa okanye ukufunxa amandla ngaphantsi kwesekondi enye xa isizukulwana kunye nokufuna ukungahambelani. Ukutsheva okuphezulu kukhupha iibhetri ngexesha{4}}eliphezulu lemfuno, kuthintelwa imfuno yezityalo ezixabisa kakhulu zerhasi yendalo. I-arbitrage yamandla ibamba inzuzo ngokubiza xa umbane othengisiweyo ubiza i-$ 20 / MWh kunye nokukhupha xa amaxabiso abetha i-$ 200 / MWh ngexesha le-spikes yemfuno.
Lo mzekelo zintathu-zichaza ukuba kutheni izibonelelo zangoku ze-BESS zinokusuka kwi-standby ukuya kumandla apheleleyo nge-10 milliseconds{2}}ngokukhawuleza kunaso nasiphi na isixhobo samafutha efosili{3}}ngelixa ngaxeshanye ilawula amaqhinga entatho-nxaxheba yemarike.
Intlawulo-yoGcino{1}}Ukukhupha umjikelo wokuSebenza
Ukusebenza okusisiseko kwendawo yokugcina amandla ebhetri kulandela umjikelo oqhubekayo, nangona ixesha kunye nokuqina kuyahluka ngokusekelwe kwiimfuno zegridi kunye neemeko zemarike.
Ngexesha leisigaba sokutshaja, indawo itsala amandla kwigridi okanye ngokuthe ngqo kwi-ekwimithombo ehlaziyekayo ekhoyo. Kwi-DC{2}}iinkqubo ezidityanisiweyo ezidityaniswe neefama zelanga, umbane uhamba kwiiphaneli zePV nge-inverter ekwabelwana ngayo ngqo kwibhetri yebhasi ye-DC, ukunciphisa ilahleko yokuguqulwa. Iisistim ezidityanisiweyo ze-AC{4} zifuna inyathelo elongezelelweyo lokuguqulwa, ukuncama malunga ne-5% yokusebenza kakuhle kodwa ukufumana ukuguquguquka kokusebenza. I-BMS isoloko ihlola imeko yentlawulo yeseli nganye, isebenzisa ulungelelwaniso olusebenzayo ukuqinisekisa ukuba akukho ntlawulo yeseli ngokukhawuleza kunezinye{7}}umlinganiselo obalulekileyo wokhuseleko kuba iiseli ze-lithium ezitshajisiweyo zinokukhupha iigesi ezinokutsha.
Isibonelelo asihlawulisi ngesantya esiphezulu ngexesha lomjikelo ngamnye. Ukutshaja okunamandla ngaphezu kwereyithi ye-0.5C (ukutshaja ukuya kwi-50% umthamo ngeyure enye) kukhawulezisa ukuthotywa, ukunciphisa i-10,000+ ubomi bomjikelo ezi nkqubo ziyilelwe. I-EMS ibala iireyithi zokuhlawulisa ezona zilungileyo ngokulinganisela amathuba engeniso angoko nangoko ngokuchasene{6}}nexabiso lexesha elide le-asethi. Ukuba amaxabiso ehoseyile akalungile{8}}axhaphakile eKhalifoniya ngeemvakwemini ezinelanga lasentlakohlaza xa imveliso yelanga igqithisa imfuno{9}}indawo inokuhlawulisa ngexabiso eliphezulu nangona igugile ngokukhawuleza, ihlawulwa ngokugcina amandla.
Ugcinoayisosimo sokwenziwa. Iibhetri{1}}zizikhupha ngokwazo malunga ne-3-5% ngenyanga kwiikhemistri ze-lithium, nangona oku kungahoywanga kwimijikelo yeyure eyi-1-4 uninzi lwamaziko asebenzayo. Okubaluleke ngakumbi kukuba kwenzeka ntoni xa isistim ihleli kwintlawulo eyinxenye. I-BMS yenza ulungelelwaniso lweeseli, iphinde ihlawule intlawulo phakathi kweeseli ukuthintela ukukhukuliseka kwamandla. Ulawulo lwe-Thermal lugcina amaqondo obushushu azinzileyo naxa iibhetri zingatshaji okanye zingatshaji, zisebenzisa malunga ne-2-3% yamandla agciniweyo njengophezulu. Iinkqubo zokucutha umlilo ziqhuba uxilongo oluqhubekayo, ukubeka esweni ukungahambi kakuhle kobushushu, ukwakhiwa kwerhasi, okanye izitenxo zombane ezinokubonisa ukubaleka kobushushu.
Ngexeshaukukhupha, inkqubo ibuyisela umva kunye neelahleko zokuguqulwa ezifanayo. Indawo yokugcina amandla ebhetri egcweleyo eyi-100MW/400MWh inika amandla kwisakhono esipheleleyo kangangeeyure ezine ibonisa -uhambo olusebenzayo olusebenzayo. Ukuqala nge-400MWh yamandla agciniweyo, ilahleko yoguqulo ngePCS, ilahleko yesiguquli, kunye nokusetyenziswa kwenkqubo encedisayo kuthetha malunga nama-340MWh ukufikelela kwigridi{7}}i-85% yokujikeleza{9}}ubuchule bohambo. Oku kusebenza kakuhle kuyahluka ngokwezinga lokukhupha. Ukukhutshwa okuKhawulezayo ngeC{12}}kumlinganiselo onganeno kancinci kunokukhutshwa kancinane, kodwa ukukwazi ukuphendula ngoko nangoko kwiigridi ezinokuthi zenzeke kwenza olu rhwebo{13} lungabinaxabiso.
Ubuhle balo mjikelo kukuguquguquka kwawo. Ngokungafaniyo nogcino olumpompelweyo lwe-hydro olufuna indawo ethile kwaye luthatha imizuzu ukuphendula, okanye izityalo ezishushu ezifuna iiyure ukuqalisa, indawo yokugcina amandla ebhetri inokusebenzisa amawaka emijikelo{1}encinci yonke imini enye. Isibonelelo sinokuhlawulisa ngexesha lentsalela yokuvelisa umoya ngo-2 AM, ukukhupha ngexesha le-6 AM kusasa ngerempu, ukutshaja kwakhona ngexesha lasemini yasemini yencopho yelanga, kwaye kuphinde kuphume kwakhona ngentsimbi yesi-6 PM ngokuhlwa kwespike{6}}lonke lo gama ubonelela ngeenkonzo zolawulo lwamaza phakathi kwaloo mijikelo mikhulu.
ULungelelaniso lweCandelo kwiMisebenzi yeXesha lokwenyani{0}
Umlingo osebenzayo wenzeka kwindlela amalungu anxibelelana ngayo kwaye alungelelanise ukwahlula{0}}izigqibo zesibini kulo lonke uncedo.
Inkqubo yoLawulo lwebhetriisebenza kumanqanaba amathathu oluhlu lwemigangatho. IiYunithi zokuJonga iBattery zilandelela iiseli zomntu ngamnye ngaphakathi kweemodyuli, umbane wokunika ingxelo kunye nedatha yeqondo lobushushu rhoqo kwi-100 milliseconds. Iiyunithi ze-BMS zomtya zidibanisa idatha ukusuka ukuya kuma-60 e-BMU, zichonga izinto ezingaqhelekanga njengeseli enye ebuthathaka enokuthi ibeke esichengeni umtya opheleleyo. I-Master BMS idibanisa amagalelo asuka kuzo zonke iintambo, isenza uncedo{5}}izigqibo ezibanzi malunga nemo yentlawulo, umthamo okhoyo, kunye nobume bokhuseleko. Xa iseli enye kwindawo yeeseli ezili-10,000 ibonisa ubushushu obuphakamileyo, i-Master BMS inokwahlula loo ntambo yonke ngaphantsi komzuzwana omnye, igcine i-99% yomthamo wendawo ngelixa ikhusela ukusilela kwe-cascade.
Qwalasela okwenzekayo ngexesha legridi yokutenxa rhoqo. Igridi yefrikhwensi yehla ukuya kwi-59.95Hz, ebonisa ukuba isizukulwana siwele ngequbuliso ngaphantsi kwemfuno. Ngaphakathi kwe-20 milliseconds, i-EMS ifumana isignali yefrikhwensi, ibala inaliti yamandla efunekayo, kwaye iyalele i-PCS ukuba iqalise ukukhupha. I-PCS irampu ukusuka kwi-zero ukuya kwi-100MW imveliso kwii-millisecond ezingama-40 ngaphezulu ngelixa i-BMS iqinisekisa ngokuqhubekayo ukuba akukho ziseli ezidlula imingcele yangoku yokukhupha ngokukhuselekileyo. Isiguquli sinyathela amandla ombane ukusuka kwimveliso ye-PCS ye-690V AC ukuya kwintambo yothumelo eyi-138kV kwezinye iimillisecond ezili-10. Ixesha elipheleleyo lokuphendula: I-70 millisecond ukusuka ekubonweni rhoqo ukuya kunikezelo lwamandla apheleleyo kwindawo yokudibanisa igridi.
Olu lungelelaniso luba nzima ngakumbi ngexesha lemisebenzi ezinzileyo. Inkqubo yolawulo lwe-thermal ibeka iliso kwiqondo lobushushu bebhetri, iyalele iinkqubo zokupholisa ukuba zisebenze xa ixesha lobushushu lidlula i-25 degree. Amazinga aphezulu okukhupha avelisa ubushushu obuninzi, ukudala iluphu yempendulo-i-EMS kufuneka ilungelelanise unikezelo lwamandla aphezulu ngokuchasene nemiqobo ye-thermal. Ngexesha leziganeko ezigqithisileyo ezifana noFebruwari 2024 eTexas ebandayo, iibhetri zabonelela ngenkxaso yegridi ebalulekileyo kodwa azikwazanga ukugcina amaxabiso aphezulu okukhupha ixesha elide ngaphandle kweenkqubo zokufudumeza ngokugqithiseleyo ezazisilwa ngamaqondo obushushu ngaxeshanye.
Inkqubo yokuguqula amandlaiphatha imisebenzi emininzi ngaxeshanye ngaphaya koguqulo olusisiseko lwe-DC{0}}. Ilawula into yamandla, inkxaso yamandla asebenzayo, kunye nokucoca i-harmonic ukuqinisekisa ukunikezelwa kwamandla acocekileyo. Iiyunithi ze-PCS zanamhlanje zisebenzisa i-IGBT okanye ii-silicon carbide inverters ezitshintsha kwi-10-20kHz, zivelisa iigridi ze-waveform ze-AC ze-sinusoidal ezichanekileyo. Xa izikhongozeli zebhetri ezininzi zikhutshwa ngaxeshanye, i-PCS ingqamanisa iziphumo zayo ukunqanda uphazamiseko olutshabalalisayo, ngakumbi njengezixhobo zeokhestra kufuneka zihlale kwisigaba ukuvelisa isandi esihambelanayo kunecacophony.
Inkqubo ye-SCADA ibonelela ngokujongwa komntu kodwa kunqabile ukuba kufuneke ungenelelo ngexesha lemisebenzi eqhelekileyo. Abasebenzisi bajonga indawo{1}}iimetriki ezibanzi ngeedeshbhodi ezibonisa imo yentlawulo, ukuphuma kwamandla, iimeko ze-alam, kunye nengeniso. I-algorithms yokuthumela ngokuzenzekelayo iphatha intlawulo yesiqhelo-imijikelo yokukhupha, ingenelela kuphela xa iimeko zemarike zenza amathuba e-arbitrage agqithise imiqobo echazwe kwangaphambili okanye xa abaqhubi begridi bekhupha imiyalelo yokuthunyelwa ngesandla ngexesha likaxakeka.
Iinkonzo zeGridi kunye noThatho-nxaxheba kwiMarike
Indlela indawo yokugcina amandla ebhetri eyingenisa ngayo ingeniso ibonisa uphuculo oluphucukileyo lwezoqoqosho olwenzeka ecaleni kwemisebenzi yobugcisa.
Ukulawulwa rhoqoibonelela ngeyona ndlela ingeniso izinzileyo. Abasebenzisi begridi bahlawula izibonelelo zokugcina amandla ebhetri ukugcina ukulungela kwaye baphendule ngokuzenzekelayo ukunxaxha kwamaza. Iziko le-100MW linokufumana i-100,000 yeedola ngenyanga kwintlawulo yomthamo ngokufumaneka nje, kunye ne-$50{7}}200 ye-MWh nganye eziziswe ngexesha lemisitho yolawulo. Le nkonzo idinga amandla amancinci ogqithiso{8}}iziganeko ezininzi zolawulo kwimizuzwana yokugqibela ukuya kwimizuzu-iyenza ilungele ukugcina ubomi bebhetri ngelixa ivelisa ukuhamba kwemali okungaguqukiyo. I-EMS ithatha inxaxheba kwezi marike ngokungenisa ii-curves zebhidi ezichaza umthamo okhoyo kunye namaxabiso kwiindawo ezahlukeneyo zokubeka rhoqo.
Amandla arbitrageibamba ukusasazeka kwexabiso phakathi kwamaxesha aphantsi kunye aphezulu{0}emfuno. Imakethi ye-ERCOT yaseTexas ibonisa oku ngokuphawulekayo. Ngexesha le-solar boom ka-2024, amaxabiso evenkile yasemini ahlala ehla ngaphantsi kwe-10 yeedola/MWh ngelixa iincopho zangokuhlwa zifikelele kwi-300 yeedola-500/MWh. Iziko elibiza i-400MWh nge-$10 kwaye likhupha nge-300 yeedola ze-grosses $116,000 kumjikelo omnye wemihla ngemihla, kuthatyathwe ilahleko yokuguqulwa kunye neendleko zokuthotywa. I-EMS iqhuba i-algorithms eqikelelwayo ebandakanya uqikelelo lwemozulu, iipateni zembali yamaxabiso, kunye{15}}nexesha lokwenyani ledatha yemarike ukunyusela le mijikelo. Ngeentsuku ezithile esona sicwangciso sinengeniso kukuqhuba imijikelo emibini enganzulwanga endaweni yomjikelo omnye onzulu, ukugcina ubomi bebhetri kumathuba aphezulu exabiso elizayo.
Iimarike zamandlaukuhlawula izibonelelo zokuqinisekisa ukufumaneka ngexesha lemfuno ephezulu, isebenza ngokufanelekileyo njenge-inshurensi ngokuchasene nokusilela kwesizukulwana. Imakethi yomthamo we-PJM, umzekelo, ifuna{1}iyure ezineebhetri zexesha lokuqinisekisa ukuba ziyakwazi ukugcina ukukhupha ngalo lonke ixesha langokuhlwa. Amaziko afumana i-$50-150 kW-ngonyaka ngamnye kwesi sibophelelo, ebonelela ngengeniso eqikelelwayo enceda ngemali yokwakha iprojekthi. Umceli mngeni wokusebenza kukulungelelanisa izibophelelo zesakhono ngokuchasene namathuba e-arbitrage yamandla{7}}ukukhutshwa kwingeniso ye-arbitrage ngeeyure ezingezizo ezizezona ziphezulu kunokushiya intlawulo enganelanga ukuzalisekisa izibophelelo zesikhundla ukuba iziganeko ezingalindelekanga zenzeka.
Ukuhlanganiswa okuhlaziyekayoiinkonzo ziye zaqhuma kwixabiso njengoko umoya kunye namandla elanga akhula. Co-ugcino olubekwe kwiifama zelanga lwenza ulawulo lwerempu, lugudisa utshintsho olukhawulezileyo xa amafu edlula phezulu. Ngaphandle kogcino, ezi ndledlana zinokungazinzisi iigridi zengingqi okanye ziqalise uhambo lombane. Ugcino lufunxa i-solar engaphezulu ngexesha lokukhula, ukuthintela ukucuthwa okuya kuchitha amandla acocekileyo kunye nengeniso. Kwimakethi ye-CAISO yaseCalifornia, ugcino luncede ukudibanisa i-33GW yomthamo welanga ngo-2024-umthamo onokuthi ujongane nokucuthwa okuqatha ngaphandle kokukwazi ukuphazamisa.
I-EMS iququzelela ukuthatha inxaxheba kuzo zonke ezi marike ngaxeshanye, ingxaki enzima yokuphucula. Ngawo nawuphi na umzuzu, iibhetri zinokuba zifumana ingeniso yolawulo ngelixa zibambe umthamo wogcino wemfuno ephezulu ngelixa ubeka iliso kumathuba e-arbitrage. I-algorithms ibeka phambili ngaphezulu{2}}iinkonzo zexabiso, ngokuzenzekela ukutshintshwa kolwabiwo lwamandla njengoko iimeko zentengiso ziguquka imini yonke.
Iinkqubo zoKhuseleko kunye noThintelo lokuFaila
Ukunika inkxalabo yoluntu malunga nemililo yebhetri ye-lithium, ukuqonda ukuba indawo yokugcina amandla ebhetri ikhusela kwaye iqulethe iziganeko ezishushu kubalulekile.
Izibonelelo zale mihla ziyasebenzaukhuselo ngobunzulukwimigangatho emininzi yokhuselo. Iinkqubo zokubona irhasi zijonga ihydrogen fluoride kunye nezinye iigesi ezikhutshwa ziibhetri ngexesha loxinzelelo lobushushu. Izivamvo zobushushu, ezibekwe kwindawo nganye kwiiseli ezimbalwa, zilumkisa i-BMS xa nayiphi na iseli idlula i-40 degree. Abenzi boluvo bangoku babona iisekethe ezimfutshane ezinokubangela ukubaleka kwe-thermal. Xa naziphi na izinzwa ezibini ziqalisa ngaxeshanye, inkqubo iqhawula ngokuzenzekelayo imitya yebhetri echaphazelekileyo kwaye ikhukulise indawo ebiyelweyo ngeearhente zokucima umlilo{5}}ngokuqhelekileyo iNovec 1230 okanye i-FM-200, esebenza ngokususa ioksijini endaweni yokutshiza amanzi anokusasaza imililo ye-lithium.
Iseli{0}}yenqanaba lokhuseleko luqala ngokhetho lwekhemistri. Iibhetri ze-lithium iron phosphate, ezimele i-65% yofakelo olutsha ngo-2024, zinozinzo oluphezulu lwe-thermal kune-nickel{4}based chemistry. Iiseli ze-LFP zinyamezela ukushisa okuphezulu ngaphambi kokungena kwi-runaway ye-thermal, kwaye ukubola kwabo kuvelisa ukushisa okuncinci kunye neegesi ezinobuthi ezimbalwa. Olu ncedo lokhuseleko luza kwiindleko zokuxinana kwamandla asezantsi, kodwa kwindawo yokugcina apho kungekho sithuba sincinci, urhwebo{7}} luthanda ukhuseleko.
Isithintelo semodyuliuyilo luthintela ukusilela kwendawo ukusuka kwi-cascading. Irekhi nganye yebhetri ihlala kumlilo wayo{1}indawo evalekileyo evalelweyo eneenkqubo ezizinikeleyo zokungenisa umoya kunye nocinezelo. Ubuncinci beemfuno zezithuba{3}}ziqhele ukuba ziimitha ezi-3 phakathi kwezikhongozeli{5}}qinisekisa ukuba umlilo kwiyunithi enye awukwazi ukutshisa izikhongozeli ezimeleneyo ngobushushu obukhazimlayo. Ngexesha lokufika komlilo kaJanuwari ka-2025 kwiMoss Landing, olu yilo lwemodyuli luqulathe isehlo kwisakhiwo esinye ngelixa i-2,200MWh eseleyo iqhubekile nokusebenza, ibonisa impumelelo yoyilo lokhuseleko lwale mihla lokugcina amandla ebhetri.
Izicwangciso zokunciphisa umlilo ziye zavela ekubeni "mawutshise" kwiindlela zokucinezela okusebenzayo. Iinkqubo zangaphambili zikhupha izikhongozeli kwaye zivumele imililo ukuba izicime{1}}akuba amandla ebhetri ephelile, inkqubo ethatha iiyure kwaye ikhupha umsi onetyhefu. Iinkqubo zangoku zisebenzisa ii-agent zoxinzelelo ngokukhawuleza xa zibhaqwa, zidibanisa i-chemical suppressants kunye nokupholisa kwamanzi kwangaphandle ukukhusela ukusabalalisa kwe-thermal. Abaphenduli bokuqala ngoku bafumana uqeqesho olukhethekileyo kwimililo ye-BES, ukufunda ukuba ezi ziganeko zifuna ixesha elongezelelweyo lokupholisa njengoko iibhetri zinokuphinda zilawule iiyure emva koxinzelelo lokuqala ukuba amaqondo obushushu eseli ahlala ephakamile.
Imeko yobalo ibalulekile. IZiko loPhando lwaMandla oMbane lilandelele iziganeko zehlabathi ze-BESS ukusuka kwi-2018-}2024, ukufumana amazinga okusilela kwehle ukusuka kwi-0.04% ukuya kwi-0.0012% yomthamo ofakiweyo{8}}ukuphuculwa kwe-97%. Uninzi lweentsilelo lusuka kwiimpazamo zesixokelelwano solawulo okanye iziphene zokufakela endaweni yeengozi zebhetri ezizenzekelayo. Akukho kufa okubangelwe kwiziganeko ze-BESS eziluncedo e-United States, nangona umlilo we-Moss Landing ubangele ukufuduka okwethutyana kwabahlali abakufutshane. Ukuthelekisa, izityalo zegesi yendalo ziye zabulala abaqhubi ngoqhushumbo, ngelixa ukukhutshwa kwezityalo zamalahle kubangela amawaka okufa kwangaphambi kwexesha ngonyaka ngongcoliseko lomoya.
Imicelimngeni, ukuthotywa, kunye{0}}nexesha elide lokuSebenza

Umthamo uyaphelaimele owona mngeni uphambili wokusebenza. Yonke intlawulo-yomjikelo wokukhupha wehlisa ikhemistri yebhetri kancinane, inciphisa kancinci indawo yokugcina. Isibonelelo esiqala ngama-400MWh amandla asebenzisekayo anokugcina kuphela ama-320MWh emva kweminyaka eli-10 yokukhwela ibhayisekile yonke imihla. Izinga lokuthotywa lixhomekeke kwizinto ezininzi:
Ubushushu bokusebenza bubaluleke kakhulu. Iibhetri zijikelezwe kwi-35℃degrade malunga ne-30% ngokukhawuleza kunezo zigcinwe kwi-25 degree, ichaza ukuba kutheni ulawulo lwe-thermal lusebenzisa i-2-3% yemveliso yamandla esibonelelo. Ubunzulu bokukhutshwa bubalulekile{12}ukuhamba ngebhayisikile phakathi kwe-20% kunye ne-80% yemo yentlawulo kwandisa ubomi xa kuthelekiswa nemijikelo epheleleyo ye-0-100%, nangona oku kunciphisa umthamo osebenzayo. Amaxabiso eentlawulo akhawulezisa ukuthotywa, kudala ukruthakruthwano phakathi kokunyuswa kwengeniso kunye nokugcinwa kwempahla. I-EMS iqhubeka nokwandisa olu rhwebo lusebenzisa iimodeli zokuthotywa eziqikelela ubomi obuseleyo phantsi kwezicwangciso zokusebenza ezahlukeneyo.
Unyino lwexeshacinezela izicelo. Uninzi lwezixhobo zigcina i-1-4 iiyure zomthamo, azonelanga ugcino lwamaxesha onyaka okanye{4}}umbane ogciniweyo weentsuku ezininzi. Esi sithintelo sisukela kuqoqosho endaweni yokuba ubude bexesha lobuchwephesha buphindwe kabini ukusuka kwiiyure ezi-2 ukuya kwezi-4 zonyusa iindleko malunga ne-60% oko usongeza umthamo webhetri ngelixa ugcina amandla afanayo ombane. Oku kucacisa ukuba kutheni i-BESS igqwesa kwibhayisekile yasebusuku kunye nolawulo lwamaza kodwa ingenako ukuthatha indawo yezityalo zerhasi yendalo ukuvelisa isiseko esizinzileyo ngexesha elongeziweyo xa izinto ezinokuhlaziywa zingasebenzi kakuhle.
Umceli mngeni wonyaka waseCalifornia ubonisa lo mqobo. Ukuveliswa kwamandla elanga kuyehla ngama-70% ukusuka ehlotyeni ukuya ebusika ngelixa imfuno ihlala iphezulu. Ukujongana nale -intsilelo yenyanga kuya kufuna i-50{7}}100x ngaphezulu komthamo wogcino kunokubonelela ngoncedo lwangoku, ngeendleko ezingaphaya kwe-100 yeebhiliyoni zeedola. Iibhetri zibamba{8}}ukudityaniswa kosuku ngobuchule kodwa zifuna ugcino olude{9}}lobude betekhnoloji{10}}njengeebhetri eziqukuqelayo, ihydrogen, okanye impompe yehydro-yokulungelelaniswa kwamaxesha onyaka.
Ukuthotywa kokusebenza ngexesha lobushushu obugqithisileyoimida yokuthembeka ngexesha lezona ziganeko zibalulekileyo zoxinzelelo lwegridi.

Abanini-zithuthi bathomalalisa le mingeni ngezicwangciso-qhinga zolawulo ezintsonkothileyo. Iziqinisekiso ngokuqhelekileyo zigubungela 70-80% ugcino umthamo phezu 10{5}}15 iminyaka, ukubonelela ngokhuseleko lwemali ekuthotyweni ngokugqithisileyo. Ezinye izibonelelo zidibanisa iikhemistri ezahlukeneyo zebhetri-zisebenzisa i-LFP yokukhwela ibhayisekile yemihla ngemihla kunye ne-NMC yexabiso eliphezulu, iziganeko zokukhupha rhoqo apho uxinano lwamandla lubaluleke ngaphezu kobomi obude. Uhlalutyo oluphezulu luqikelela ukusilela ngaphambi kokuba kwenzeke, ukuvumela ukutshintshwa kothintelo lweemodyuli ezithotywayo kunokulinda ukungaphumeleli ngokupheleleyo.
Imibuzo ebuzwa qho
Isixhobo sokugcina amandla ebhetri sinokusabela ngokukhawuleza kangakanani kwiimfuno zegridi?
Izibonelelo zale mihla zitshintsha ukusuka kwi-standby ukuya kwimveliso yamandla apheleleyo kwi-10-70 milliseconds, ngokuqikelelwa ngokuphindwe ka-100 ngokukhawuleza kunezityalo zerhasi yendalo. Le mpendulo ikufutshane-ekhawulezayo ibenza baxabiseke ngakumbi kulawulo lwamaza egridi, apho amaxesha okuphendula angaphantsi kowesibini anqanda ukusilela kwe-cascading ngexesha lokuvelisa ngesiquphe okanye utshintsho lwebango.
Kwenzeka ntoni kwiibhetri xa zingasafaneleki ukugcina igridi?
Iibhetri zidla ngokuthatha umhlala-phantsi kwinkonzo yegridi xa umthamo uthotywa ukuya kuma-70-}80% yohlelo lokuqala, kodwa zigcina ubomi obaneleyo kwizicelo ezingabalulekanga kangako. Amaziko amaninzi acwangcisa ukusetyenziswa kobomi besibini kwiinkqubo zokugcina indawo yokuhlala okanye izibonelelo zokutshaja isithuthi sombane apho iimfuno zokusebenza ziphantsi. Ekugqibeleni, iibhetri zingena kwiinkqubo zokuphinda zisetyenziswe ezibuyisela i-90-95% yezinto ezixabisekileyo eziquka i-lithium, i-cobalt, kunye ne-nickel ukuze zisetyenziswe kwimveliso entsha yebhetri.
Ngaba izibonelelo zokugcina ibhetri zisebenza ngokuzimeleyo ngokupheleleyo kwimithombo yamandla ahlaziyekayo?
Ewe, izibonelelo ezizimeleyo zisebenza ngokuzimeleyo, zihlawuliswa nakweyiphi na igridi{0}edityanisiweyo yomthombo wokuvelisa kunye nokukhupha ngokusekelwe kwiimfuno zegridi okanye iimeko zemarike. Malunga ne-55% yeeprojekthi zebhetri ezintsha zase-US ngo-2024 bezizimele, ngelixa i-45% -zibekwe kwifama zesola okanye zomoya. Umkhwa obhekiselele kwizibonelelo ezizimeleyo zibonakalisa ukuguquguquka kwazo ekuboneleleni ngeenkonzo ezininzi zegridi ngaphaya kokuhlanganiswa okuhlaziyekayo.
Ukuqukumbela
Ubuhle bokusebenza kwendawo yokugcina amandla ebhetri busekukwazini ukuqulunqa amawaka ezinto kunye ne-algorithms entsonkothileyo ibe zizigqibo zokwahlulwa{0}}zesibini ezigcina umbane uhamba ngokuthembekileyo. Njengoko umthamo wehlabathi ugqithise i-100GW ngo-2025-iphinda kabini kwiminyaka nje emibini-ezi zixhobo zavela kwitekhnoloji yovavanyo ukuya kwiziseko ezingundoqo zegridi. Impumelelo yabo ekuthatheni indawo yezityalo zerhasi encopho yendalo ngelixa idibanisa amandla avuselelekayo ibonisa ukuba imingeni yokusebenza yempendulo ekhawulezileyo, ulawulo lobushushu, kunye nolawulo lokuthotywa komgangatho iye yasonjululwa kakhulu ngeenkqubo zokhuseleko ezicwangcisiweyo kunye ne-algorithms yolawulo oluntsonkothileyo.
