I-PV inverter umenzi wecandelo lokugcinwa kwamandla e-Sungrow liye labandakanyeka kwiisombululo zenkqubo yokugcina amandla ebhetri (BESS) ukususela ngo-2006. Ithumele i-3GWh yokugcina amandla kwihlabathi jikelele ngo-2021.
Ishishini layo lokugcina amandla liye landa ukuze libe ngumboneleli we-turnkey, i-BESS edibeneyo, kuquka i-Sungrow ye-in-house system yokuguqula amandla (PCS) iteknoloji.
Inkampani ibekwe kwi-10 ephezulu ye-BESS edibanisa inkqubo ye-BESS kuvavanyo lonyaka lwe-IHS Markit lwesithuba ngo-2021.
Sijonge kuyo yonke into ukusuka kwindawo yokuhlala ukuya kwindawo enkulu - ngokugxila kakhulu kwi-solar-plus-storage kwi-utility-scale-sicela uAndy Lycett, umphathi welizwe lase-Sungrow e-UK nase-Ireland, ngeembono zakhe malunga neendlela ezinokubumba. ishishini kwiminyaka ezayo.
Zeziphi ezinye zeendlela eziphambili zetekhnoloji ocinga ukuba ziya kubumba ugcino lwamandla ngo-2022?
Ulawulo lwe-Thermal lweeseli zebhetri lubaluleke kakhulu ekusebenzeni kunye nokuphila ixesha elide kuyo nayiphi na inkqubo ye-ESS.Ngaphandle kwenani lemijikelezo yomsebenzi, kunye neminyaka yeebhetri, inempembelelo enkulu ekusebenzeni.
Ubomi beebhetri buchaphazeleka kakhulu kulawulo lwe-thermal.Ulawulo olungcono lwe-thermal, ixesha elide lobomi lidityaniswa nesiphumo esiphezulu somthamo osebenzisekayo.Zimbini iindlela eziphambili zokupholisa itekhnoloji: ukupholisa umoya kunye nokupholisa ulwelo, iSungrow ikholelwa ukuba ugcino lwamandla ebhetri lulwelo olupholileyo luya kuqalisa ukulawula imakethi ngo-2022.
Oku kungenxa yokuba ukupholisa ulwelo kuvumela iiseli ukuba zibenobushushu obufanayo ngakumbi kwisixokelelwano sonke ngelixa zisebenzisa amandla amancinci okufakwayo, ukumisa ukutshisa okugqithisileyo, ukugcina ukhuseleko, ukunciphisa ukuthotywa kunye nokwenza ukuba ukusebenza okuphezulu kuvumeleke.
I-Power Conversion System (PCS) yinxalenye ephambili yesixhobo esidibanisa ibhetri kunye negridi, ukuguqula amandla e-DC agcinwe kwi-AC amandla ahambayo.
Ukukwazi kwayo ukubonelela ngeenkonzo ezahlukeneyo zegridi ngaphezu kwalo msebenzi kuya kuchaphazela ukuthunyelwa.Ngenxa yophuhliso olukhawulezayo lwamandla avuselelekayo, abaqhubi begridi bahlola amandla anokubakho e-BESS ukuxhasa ngokuzinza kwenkqubo yamandla, kwaye bakhupha iinkonzo ezahlukeneyo zegridi.
Ngokomzekelo, [e-UK], i-Dynamic Containment (DC) yasungulwa ngo-2020 kwaye impumelelo yayo iye yavula indlela ye-Dynamic Regulation (DR) / Dynamic Moderation (DM) ekuqaleni kwe-2022.
Ngaphandle kwezi nkonzo zefrikhwensi, iGridi yeSizwe iphinde yakhupha iStable Pathfinder, iprojekthi yokufumana ezona ndlela zingabizi kakhulu zokujongana nemiba yozinzo kuthungelwano.Oku kubandakanya ukuvavanya inertia kunye negalelo leSekethe eMfutshane ye-grid-forming inverters.Ezi nkonzo azinakunceda kuphela ukwakha inethiwekhi eyomeleleyo, kodwa zibonelela ngengeniso ebalulekileyo kubathengi.
Ngoko ukusebenza kwe-PCS ukubonelela ngeenkonzo ezahlukeneyo kuya kuchaphazela ukhetho lwenkqubo ye-BESS.
I-DC-Coupled PV + ESS iya kuqalisa ukudlala indima ebaluleke ngakumbi, njengoko i-asethi ekhoyo ekhoyo ijonge ukunyusa ukusebenza.
I-PV kunye ne-BESS zidlala indima ebalulekileyo kwinkqubela phambili kwi-net-zero.Indibaniselwano yezi teknoloji zimbini ziye zajongwa kwaye zasetyenziswa kwiiprojekthi ezininzi.Kodwa uninzi lwazo ludityaniswe ne-AC.
Inkqubo edibeneyo ye-DC inokugcina i-CAPEX yezixhobo eziphambili (i-inverter system / i-transformer, njl njl), ukunciphisa unyawo lomzimba, ukuphucula ukusebenza kakuhle kokuguqulwa kunye nokunciphisa ukuveliswa kwe-PV kwimiba ye-DC / AC ephezulu, enokuba luncedo lwezorhwebo. .
Ezi nkqubo ze-hybridi ziya kwenza imveliso ye-PV ilawuleke ngakumbi kwaye ihanjiswe eya kwandisa ixabiso lombane owenziweyo.Ngaphezu koko, inkqubo ye-ESS iya kukwazi ukufunxa amandla ngamaxesha aphantsi xa uxhulumaniso luya kuba lungasebenzi, ngaloo ndlela lubila i-asethi yoqhagamshelwano lwegridi.
Iinkqubo zexesha elide zokugcina amandla nazo ziya kuqalisa ukwanda ngo-2022. I-2021 ngokuqinisekileyo yayingunyaka wokuvela kwe-PV ye-utility-scale e-UK.Iimeko ezihambelana nokugcinwa kwamandla exesha elide kuquka ukuchetywa kwepeak, imarike yomthamo;ukuphuculwa komlinganiselo wokusetyenziswa kwegridi ukunciphisa iindleko zothumelo;ukunciphisa iimfuno zomthwalo wencopho yokunciphisa utyalo-mali lokuphucula umthamo, kwaye ekugqibeleni kuncitshiswe iindleko zombane kunye nobunzulu bekhabhoni.
Imarike ibiza ukugcinwa kwamandla ixesha elide.Sikholelwa ukuba u-2022 uya kuqalisa ixesha lobuchwephesha obunjalo.
I-Hybrid Residential BESS iya kudlala indima ebalulekileyo kwimveliso yamandla ohlaza / inguqu yokusetyenziswa kwinqanaba lekhaya.Ixabiso-esebenzayo, ikhuselekile, i-Hybrid yokuhlala i-BESS edibanisa i-PV yophahla, ibhetri kunye ne-bi-directional plug-and-play inverter ukufezekisa i-microgrid yasekhaya.Ngokunyuka kweendleko zamandla ezilumayo kunye neteknoloji elungele ukunceda ukwenza utshintsho, silindele ukuthatha ngokukhawuleza kule ndawo.
I-Sungrow's ST2752UX entsha ye-ST2752UX inkqubo yokugcina amandla ebhetri epholileyo kunye nesisombululo se-AC-/DC-sokudibanisa kwizityalo zamandla ezisetyenziswayo.Umfanekiso: Sungrow.
Kuthekani kule minyaka iphakathi ngoku kunye no-2030-inokuba yintoni enye yeendlela zetekhnoloji yexesha elide eziphembelela ukuhanjiswa?
Kukho izinto ezininzi eziya kuchaphazela ukuhanjiswa kwenkqubo yokugcina amandla phakathi kuka-2022 ukuya ku-2030.
Ukuphuhliswa kobuchwepheshe obutsha beeseli zebhetri obunokufakwa kwisicelo sorhwebo kuya kuqhubela phambili ukukhutshwa kweenkqubo zokugcina amandla.Kwiinyanga ezimbalwa ezidlulileyo, siye sabona ukunyuka okukhulu kwiindleko ze-lithium ezikhokelela ekunyuseni kwexabiso leenkqubo zokugcina amandla.Oku kusenokungazinzisi kwezoqoqosho.
Silindele ukuba kule minyaka ilishumi izayo, kuya kubakho izinto ezintsha ezininzi ekuqukuqeleni ibhetri kunye nemeko yolwelo ukuya kuphuhliso lwendawo yebhetri eqinileyo.Zeziphi iitekhnoloji ezinokuthi zisebenze ziya kuxhomekeka kwixabiso lemathiriyeli ekrwada kunye nokuba iikhonsepthi ezintsha zinokuziswa ngokukhawuleza kangakanani kwintengiso.
Ngokunyuka kwesantya sokusasazwa kweenkqubo zokugcina amandla ebhetri ukusukela ngo-2020, ukuphinda kusetyenziswe ibhetri kufuneka kuthathelwe ingqalelo kwiminyaka embalwa ezayo xa kuphunyezwa 'Isiphelo soBomi'.Oku kubaluleke kakhulu ukugcina imeko-bume ezinzileyo.
Sele kukho amaziko ophando amaninzi asebenza kuphando lokurisayikilishwa kwebhetri.Bagxile kwimixholo efana 'nokusebenzisa i-cascade' (ukusebenzisa izixhobo ngokulandelelanayo) kunye 'nokudilizwa ngokuthe ngqo'.Isixokelelwano sokugcina amandla kufuneka siyilwe ukuze kuvumeleke ukugaywa kwakhona.
Ukwakhiwa kwenethiwekhi yegridi kuya kuchaphazela ukuthunyelwa kweenkqubo zokugcina amandla.Ekupheleni kweminyaka yoo-1880, kwabakho umlo wolawulo lothungelwano lombane phakathi kwenkqubo ye-AC kunye neenkqubo ze-DC.
I-AC iphumelele, kwaye ngoku isisiseko segridi yombane, nakwinkulungwane yama-21.Nangona kunjalo, le meko iyatshintsha, kunye nokungena okuphezulu kweenkqubo zombane zamandla ukususela kwiminyaka elishumi edlulileyo.Sinokubona uphuhliso olukhawulezayo lweenkqubo zamandla eDC ukusuka kwi-high-voltage (320kV, 500kV, 800kV, 1100kV) ukuya kwiiNkqubo zoSasazo lweDC.
Ugcino lwamandla ebhetri lunokulandela olu tshintsho lwenethiwekhi kwiminyaka elishumi ezayo okanye njalo.
I-Hydrogen sisihloko esishushu kakhulu malunga nophuhliso lweenkqubo zokugcina amandla kwixesha elizayo.Akungabazeki ukuba iHydrogen iya kudlala indima ebalulekileyo kwindawo yokugcina amandla.Kodwa ngexesha lohambo lophuhliso lwe-hydrogen, itekhnoloji ekhoyo evuselelekayo nayo iya kuba negalelo elikhulu.
Sele kukho iiprojekthi zovavanyo ezisebenzisa i-PV + ESS ukunika amandla kwi-electrolysis yokuvelisa i-hydrogen.I-ESS iya kuqinisekisa umbane oluhlaza / ongaphazamisekiyo ngexesha lenkqubo yokuvelisa.
