Isigaba sokugcina amandla somkhiqizi we-PV we-Sungrow besibambe iqhaza ohlelweni lokugcina amandla ebhethri (BESS) kusukela ngo-2006. Sithumele i-3GWh yesitoreji samandla emhlabeni jikelele ngo-2021.
Ibhizinisi layo lokugcina amandla liye landa ukuze libe umhlinzeki we-turnkey, i-BESS edidiyelwe, okuhlanganisa nobuchwepheshe be-Sungrow's in-house power conversion system (PCS).
Le nkampani ikleliswe kwabangu-10 abahamba phambili besistimu ye-BESS emhlabeni wonke ocwaningweni lwaminyaka yonke lwe-IHS Markit lwesikhala lwango-2021.
Sihlose yonke into kusuka endaweni yokuhlala kuya enkulu - ngokugxila kakhulu ekugcinweni kwelanga kanye ne-solar-plus-scale - sicela u-Andy Lycett, umphathi wezwe lika-Sungrow wase-UK nase-Ireland, ngemibono yakhe mayelana nezitayela ezingase zibumbe. imboni eminyakeni ezayo.
Yiziphi ezinye zezitayela zobuchwepheshe ezibalulekile ocabanga ukuthi zizoshintsha ukusetshenziswa kwesitoreji samandla ngo-2022?
Ukuphathwa Okushisayo kwamaseli ebhethri kubaluleke kakhulu ekusebenzeni nasekuphileni isikhathi eside kwanoma iyiphi isistimu ye-ESS.Ngaphandle kwenani lemijikelezo yomsebenzi, kanye neminyaka yamabhethri, inomthelela omkhulu ekusebenzeni.
Ukuphila kwamabhethri kuthinteka kakhulu ekuphathweni kwe-thermal.Ukuphatha okushisayo okungcono, isikhathi eside sokuphila sihlanganiswa nomphumela ophezulu womthamo osebenzisekayo.Kunezindlela ezimbili eziyinhloko zobuchwepheshe bokupholisa: ukupholisa umoya nokupholisa uketshezi, i-Sungrow ikholelwa ukuthi isitoreji samandla ebhethri epholile sizoqala ukubusa imakethe ngo-2022.
Lokhu kungenxa yokuthi ukupholisa uketshezi kuvumela amaseli ukuthi abe nezinga lokushisa elifanayo kakhudlwana kusistimu yonke ngenkathi esebenzisa amandla amancane okokufaka, ukumisa ukushisa ngokweqile, ukulondoloza ukuphepha, ukunciphisa ukuwohloka futhi kuvumela ukusebenza okuphezulu.
I-Power Conversion System (PCS) iyisisetshenziswa esibalulekile esixhuma ibhethri negridi, iguqule amandla agciniwe e-DC abe amandla adluliswa yi-AC.
Amandla ayo okuhlinzeka ngamasevisi egridi ahlukene ngaphezu kwalo msebenzi azophazamisa ukuthunyelwa.Ngenxa yokuthuthukiswa okusheshayo kwamandla avuselelekayo, opharetha begridi bahlola amandla anamandla e-BESS okusekela ngokuzinza kwesistimu yamandla, futhi bakhipha izinhlobonhlobo zezinsizakalo zegridi.
Isibonelo, [e-UK], i-Dynamic Containment (DC) yethulwa ngo-2020 futhi impumelelo yayo isivule indlela ye-Dynamic Regulation (DR)/Dynamic Moderation (DM) ngasekuqaleni kuka-2022.
Ngaphandle kwalezi zinsizakalo zefrikhwensi, i-National Grid iphinde yethula i-Stability Pathfinder, iphrojekthi yokuthola izindlela ezingabizi kakhulu zokubhekana nezinkinga zokuzinza kunethiwekhi.Lokhu kubandakanya ukuhlola inertia kanye Nomnikelo Wesekethe Emfishane wama-inverter asekelwe kugridi.Lezi zinsizakalo azikwazi nje ukusiza ukwakha inethiwekhi eqinile, kodwa futhi zinikeze imali ebalulekile kumakhasimende.
Ngakho-ke ukusebenza kwe-PCS ukuhlinzeka ngamasevisi ahlukene kuzothinta ukukhethwa kohlelo lwe-BESS.
I-DC-Coupled PV+ESS izoqala ukudlala indima ebaluleke kakhulu, njengoba izimpahla zokukhiqiza ezikhona zibheke ukuthuthukisa ukusebenza kahle.
I-PV ne-BESS zidlala indima ebalulekile ekuthuthukeleni ku-net-zero.Inhlanganisela yalezi zindlela zobuchwepheshe ezimbili zihlolisisiwe futhi zasetshenziswa kumaphrojekthi amaningi.Kodwa eziningi zazo zihlanganiswe ne-AC.
Uhlelo oluhlanganisiwe lwe-DC lungasindisa i-CAPEX yemishini eyinhloko (isistimu ye-inverter/i-transformer, njll), yehlise unyawo lomzimba, ithuthukise ukusebenza kahle kokuguqulwa futhi yehlise ukuncishiswa kokukhiqizwa kwe-PV esimeni sezilinganiso eziphezulu ze-DC/AC, ezingaba yinzuzo yezentengiselwano. .
Lezi zinhlelo ze-hybrid zizokwenza ukuphuma kwe-PV kulawuleke futhi kuhanjiswe kalula okuzokhuphula inani likagesi okhiqizwayo.Ngaphezu kwalokho, isistimu ye-ESS izokwazi ukumunca amandla ngezikhathi ezishibhile lapho uxhumo luzoba lukhuni, ngaleyo ndlela lujuluke ifa lokuxhuma kwegridi.
Amasistimu okugcina amandla esikhathi eside nawo azoqala ukwanda ngo-2022. Unyaka ka-2021 ngokuqinisekile bekuwunyaka wokuvela kwe-PV yesikali esisetshenziswayo e-UK.Izimo ezifanele ukugcinwa kwamandla okuhlala isikhathi eside okuhlanganisa ukushefa okuphezulu, imakethe yamandla;ukuthuthukiswa kwesilinganiso sokusetshenziswa kwegridi ukuze kwehliswe izindleko zokudlulisela;ukunciphisa izimfuno zomthwalo omkhulu ukuze kuncishiswe ukutshalwa kwezimali kokuthuthukiswa kwamandla, futhi ekugcineni kuncishiswe izindleko zikagesi kanye nomfutho wekhabhoni.
Imakethe ibiza ukugcinwa kwamandla kwesikhathi eside.Sikholelwa ukuthi u-2022 uzoqala inkathi yobuchwepheshe obunjalo.
I-Hybrid Residential BESS izodlala indima ebalulekile ekukhiqizeni amandla aluhlaza / ukusetshenziswa kwezinguquko ezingeni lasekhaya.Ibiza izindleko, iphephile, iHybrid Residence BESS ehlanganisa i-PV yophahla, ibhethri kanye ne-bi-directional plug-and-play inverter ukuze kuzuzwe igridi yasekhaya.Ngokukhuphuka kwezindleko zamandla ezilumayo kanye nobuchwepheshe bulungele ukusiza ukwenza ushintsho, silindele ukuthi kuthathwe ngokushesha kule ndawo.
Uhlelo olusha lwe-Sungrow lwe-ST2752UX lokugcina amandla ebhethri olupholile olunesixazululo se-AC-/DC-coupling sezitshalo zamandla esikali esisetshenziswayo.Isithombe: Sungrow.
Kuthiwani eminyakeni ephakathi kwamanje no-2030 - yini enye yezindlela zobuchwepheshe zesikhathi eside ezithonya ukuthunyelwa?
Kunezici ezimbalwa ezizothinta ukusetshenziswa kwesistimu yokugcina amandla phakathi kuka-2022 kuya ku-2030.
Ukuthuthukiswa kobuchwepheshe obusha bamaseli ebhethri obungafakwa ekusetshenzisweni kwezentengiso kuzoqhubeza phambili ukukhishwa kwamasistimu okugcina amandla.Ezinyangeni ezimbalwa ezedlule, sibone ukweqa okukhulu kwezindleko ze-lithium okuholela ekwenyukeni kwentengo yezinhlelo zokugcina amandla.Lokhu kungase kungazinzisi kwezomnotho.
Silindele ukuthi eminyakeni eyishumi ezayo, kuzoba nokuqanjwa okuningi ekuthuthukisweni kwebhethri eligeleza kanye nesimo se-liquid kuya kumkhakha webhethri wesimo esiqinile.Ibuphi ubuchwepheshe obuzosebenza buzoncika ezindlekweni zezinto ezingavuthiwe nokuthi imiqondo emisha ingalethwa ngokushesha kangakanani emakethe.
Ngokukhula kwesivinini sokuphakelwa kwamasistimu okugcina amandla ebhethri kusukela ngo-2020, ukugaywa kabusha kwebhethri kufanele kucatshangwe eminyakeni embalwa ezayo lapho kufinyelelwa 'Ukuphela Kokuphila'.Lokhu kubaluleke kakhulu ukugcina indawo esimeme.
Sekuvele kunezikhungo eziningi zocwaningo ezisebenza ocwaningweni lokugaywa kabusha kwamabhethri.Bagxile ezindikimbeni ezifana 'nokusetshenziswa kwe-cascade' (ukusebenzisa izinsiza ngokulandelana) kanye 'nokuhlakazwa ngqo'.Isistimu yokugcina amandla kufanele yakhelwe ukuvumela kalula ukugaywa kabusha.
Isakhiwo senethiwekhi yegridi sizophinde sibe nomthelela ekusetshenzisweni kwamasistimu okugcina amandla.Ekupheleni kwawo-1880, kwaba nempi yokubusa kwenethiwekhi kagesi phakathi kwesistimu ye-AC kanye nezinhlelo ze-DC.
I-AC iwinile, futhi manje isiyisisekelo segridi kagesi, ngisho nangekhulu lama-21.Nokho, lesi simo siyashintsha, ngokungena okuphezulu kwamasistimu kagesi kagesi kusukela eminyakeni eyishumi edlule.Singabona ukuthuthuka okusheshayo kwamasistimu kagesi e-DC ukusuka ku-high-voltage (320kV, 500kV, 800kV, 1100kV) kuya ku-DC Distribution Systems.
Isitoreji samandla ebhethri singalandela lolu shintsho lwenethiwekhi eminyakeni eyishumi ezayo noma ngaphezulu.
I-Hydrogen iyisihloko esishisayo kakhulu mayelana nokuthuthukiswa kwezinhlelo zokugcina amandla esikhathini esizayo.Akungabazeki ukuthi i-Hydrogen izodlala indima ebalulekile esizindeni sokugcina amandla.Kodwa phakathi nohambo lokuthuthukiswa kwe-hydrogen, ubuchwepheshe obukhona obuvuselelekayo nabo buzofaka isandla kakhulu.
Sekuvele kukhona amaphrojekthi wokuhlola asebenzisa i-PV+ESS ukunikeza amandla ku-electrolysis okukhiqizwa kwe-hydrogen.I-ESS izoqinisekisa ukunikezwa kwamandla okuluhlaza/okungaphazanyiswa phakathi nenqubo yokukhiqiza.
