I-China iphumelele inqanaba elikhulu kwiigridi-scale yokugcina amandlangokugqitywa kwelona likhulu ehlabathiniibhetri ye-vanadium redox flow (VRFB)iprojekthi. Ifumaneka kwiNqila yaseJimusar, eXinjiang, esi senzo sikhulu, sikhokelwa liQela le-China Huaneng, sidibanisa inkqubo yebhetri engama-200 MW / 1 GWh VRFB enefama enkulu ye-1 GW yelanga.
Emele utyalo-mali lwe-CNY 3.8 yeebhiliyoni (malunga ne-520 yezigidi zeedola), iprojekthi ihamba ngeehektare ze-1,870. Nje ukuba usebenze ngokupheleleyo, kuqikelelwa ukuba kuza kuvelisa i-1.72 TWh yombane ococekileyo rhoqo ngonyaka, okunegalelo ekuncitshisweni okumandla okungaphezulu kwe-1.6 yezigidi zeetoni zokukhutshwa kweCO₂ ngonyaka.
Umsebenzi ongundoqo wolu fakelo lweVRFB kukujongana nokuphazamiseka okukhoyo kweamandla elanga. Yenzelwe iiyure ezintlanu zokukhutshwa okuqhubekayo, isebenza njenge-buffer ebalulekileyo kunye nokuzinzisa kwigridi yendawo. Obu buchule bubaluleke kakhulu kwi-Xinjiang enobutyebi obutyebileyo, apho amandla elanga kunye nomoya anokuthi ngokwembali ajongane nemiceli mngeni evela ekucuthekeni nasekuthintelweni kothumelo.
1. UkuPhakamisa koGcino kunye neeTekhnoloji eziFanayo
Isikali sale projekthi yenkqubo yebhetri ye-redox ye-VRFB igxininisa ukungxamiseka kwehlabathi kwizisombululo zokugcinwa kwamandla amakhulu, ixesha elide ukudibanisa ukuhlaziya ngokufanelekileyo. Ngelixa itekhnoloji yebhetri yeVRFB igqwesa kwizicelo ezifuna ubomi bomjikelo omde kakhulu, ukhuseleko olunomthamo omkhulu we-electrolyte, kunye nokuthotywa okuncinci kumashumi eminyaka, obunye ubuchwephesha obunjeIibhetri zeLithium Iron Phosphate (LFP).zizindlu zamandla kumacandelo ahlukeneyo.
IInkqubo yebhetri yeLFP, njengazo sisebenza ngokukhethekileyo kuzo, zibonelela ngoncedo olwahlukileyo:
- ⭐Uxinaniso lwaMandla oluPhezulu: Ukuhambisa amandla amaninzi kwindawo encinci yonyawo, ilungele ufakelo oluxinzelelekanga kwindawo.
- ⭐Ukusebenza okugqwesileyo kohambo olujikelezayo: Ukunciphisa ilahleko yamandla ngexesha lokuhlawula / ukukhupha imijikelezo.
- ⭐ Ukhuseleko olungqiniweyo:Idume ngozinzo olukhethekileyo lwe-thermal kunye neekhemikhali.
- ⭐ Iindleko eziFanelekileyo zokuHamba ibhayisekile ngeMihla: Isebenza kakhulu kwintlawulo yemihla ngemihla/ukukhutshwa kwezicelo ezinje ngokucheba okuphezulu kunye nolawulo lokuphindaphinda.
2. I-Synergizing Technologies ye-Stable Grid
VRFBs kunyeUkugcinwa kwebhetri ye-LFPbadla ngokuphelelisana, hayi abantu abakhuphisana ngokuthe ngqo. I-VRFB ifanelekele ngokufanelekileyo ukugcinwa kwexesha elide (iiyure ezi-4+, iintsuku ezinokuthi zibe kho) kunye neeprojekthi apho ubude beminyaka emininzi bubalulekile. I-LFP ikhanya kwizicelo ezifuna ukuxinana kwamandla aphezulu, ukuphendula ngokukhawuleza, kunye nokusebenza okuphezulu kokuhamba ngebhayisikile yemihla ngemihla (ngokuqhelekileyo i-2-4 ubude beyure). Kunye, ezi zisombululo zahlukeneyo zokugcina amandla zenza umqolo wegridi eyomelelayo, enokuvuselelwa ngamandla.
Iprojekthi ye-VRFB enkulu yaseTshayina luphawu olucacileyo: ubungakanani obukhulu, ukugcinwa kwexesha elide akuseyona ingcamango, kodwa iyinyani ebalulekileyo yokusebenza. Njengoko imfuno yozinzo lwegridi kunye nokudityaniswa okuvuselelekayo kuhamba ngokukhawuleza kwihlabathi jikelele, ukusasazwa ngobuchule kuzo zombini iVRFB kunye nokuqhubela phambili.Ibhetri ye-LFPIinkqubo ziya kuba yimfuneko kwikamva lamandla azinzileyo.
