Izinkinga Ezibalulekile Zokugcina Amathuba Okugcina Imali Yomthwakazi

Ukunciphisa Izindleko Zokusebenza Kwezinkampani Zokusebenza Kwamandla Ngokusebenza Kwamandla

Ukuthintana Kwesikhathi Nokuthintana Kwesikhathi Sokusebenza Kwamandla Kufundiswa

Izinqubo zokugcina imithwalo yemvelo (energy storage systems) zincoma lezi zindlela zokuthinteka kwezimali eziningi zokusebenzisa imvelo ngokuphelele ngokuchaza ngokuthi ukuguqula umkhawulo wokusebenza (load shifting) nokuthenga nokuthengisa ngokuhambisana kwezikhathi zokusebenza (TOU arbitrage). Umthwalo wokubhekisele kule ndlela uyisodwa: izibonelo zifaka amabhatari abo lapha imvelo iyadlula ngokucacile kuma- off-peak times, emva kwalokho bafunda kulezi zimfihlo zokusebenza zabo lapha imvelo iphakeme kuma-peak hours. Lokhu kusobala umkhawulo wokusebenza kwabo ngokujwayelekile futhi kususa lezi zindlela zokuthinteka kwezimali ngokuphelele. Izibonelo zonke zithinteka ngalezi zindlela zokuthinteka kwezimali ngokubhekisele kwezinye zokuthinteka kwezimali kumzuzu ngokuphelele, okuyizinye kwezikhathi ezingama-15 kuze ne-30 emzuzwini wokusebenza kwezimali, futhi kungathinta kusukela ku-30% kuze ne-70% yezimali zokusebenza ngokuphelele. Lapha izindawo ziyasiza kakhulu ukuthinteka kwezikhathi zokuthinteka kwezimali, iziphumo zezibonelo zokusebenza zibonisa ukuthi kufika kusukela ku-20% kuze ne-36% kokuthinteka kwezimali kuphela.

Isiphumo Esikwanele Kwezinto: Isibonelo Sesibonelo Sesikomisheni Ekalifoniya

Enye ifektri eCalifornia yafaka uhlelo lwamabhethri olunezikhungo eziphakeme ezingama-500 kW nama-2 MWh ukuze lusebenze kulezo zikhathi ezibizayo lapho ugesi ushibhile. Okwenzeka ngokulandelayo kwaba okuhlaba umxhwele. Lolu hlelo lwenza ukusetshenziswa kwamandla aphezulu kwehle kusuka ku-1 000 kW kuya ku-700 kW kuphela phakathi nalawo mahora abiza kakhulu. Lokho kusho ukuthi bakwazile ukunciphisa ukusetshenziswa kwabo okuphezulu ngamaphesenti angaba ngu-30. Futhi kuthiwani ngemali oyilondolozile? Bakhuluma cishe ngama-$5,600 angaphansi ngenyanga ngalezo zindleko zokufuna kuphela, okusho ukuthi basika ingxenye ye-akhawunti yabo kagesi cishe ngesigamu. Uma sibheka konke ukonga ndawonye kuhlanganise nezindleko eziphansi zokufuna nokusebenzisa amathuba okuhluka kwezinga lesikhathi sokusetshenziswa, lonke utshalomali lwabuyiselwa ngokuphelele ngemva kweminyaka emihlanu nje yokusebenza.

Ukuhlehlisa Ukutshalwa Kwezimali Kwezingqalasizinda Zokuxhumana Ngogesi Ezisebenzisa Ukugcinwa Kwamandla

Izindlela Ezingenazintambo: Ukonga Izindleko Nokuthuthukiswa Kwezokuhleleka

Ukugcinwa kwamandla kuye kwavela njengenye indlela eqinile ngaphandle kwezintambo (NWA) esiza ukugwema ukuthuthukiswa okubizayo kwezinhlelo zokudlulisa nokusabalalisa ngokunciphisa ukuxinana ezindaweni ezithile. Ukubeka amadivaysi okugcina ugesi eduze kwezindawo ezinenkinga kuwenza akwazi ukuqoqa ugesi owengeziwe lapho kunesidingo esikhulu bese ewukhulula kamuva. Le ndlela ingenza ukuthi ukutshalwa kwezimali ezidingekayo ezingqalasizinda kubambezeleke iminyaka engu-5 kuya kwengu-10, okusho ukuthi nezinkampani zezokuphakelwa komphakathi zingasindisa imali eningi. Olunye ucwaningo lwathi imali elondoloziwe iphakathi kuka-$740,000 ngomsebenzi ngamunye obekelwe eceleni (Ponemon Institute, 2023). Izinto zihamba ngokushesha nasemhlabeni wezomthetho. Njengamanje, izifundazwe ezingu-32 kulo lonke elase-US zinemithetho edinga ukuba kuhlolwe izindlela zokugcina izinto ngaphambi kokuba kuvunyelwe noma yimiphi imiklamo emisha yengqalasizinda. Ngokwesibonelo, cabanga ngeNew York. Uhlelo lwabo lwe-Reforming the Energy Vision (REV) empeleni ludinga lokhu kuhlolwa kwe-NWA, futhi lokhu kuye kwaphakamisa ukusetshenziswa kulo lonke izwe eminyakeni yamuva.

Amasimbi okugcina amandla akhona kwe-NWAs asinika iziphakamiso ezintathu eziphathelene nako:

• Ukusebenza Kwezindleko : Ukuthenga kweminyaka yokuqala kungaphezulu kuka-40–60% ngokulinganisa nokubuyisa amandla okunye amandla okukhanya
• Ukwehla : Ukufakwa kwe-modular kusinika ukuthi sibuyekele isimo sokusebenza ngokuphelele ngokuchaza kwezinkinga zokusebenza
• Ukusebenza kwezimbili : Amasimbi angasebenze ngokuhlanganisa ukuncima kokuphakama, ukulungisa ifrekhwensi, noma ukusiza kwe-voltage

Kungafani nesikhundla sezinkulungwane ezihlukene ezidinga ukuthatha iminyaka emibili noma ngaphezu koko ukuthola izinhlobo zokuzivikela nokubuyisa, ukufaka amasimbi kuyadlula ukuncima ngeminyaka eyodwa—futhi kuyabusa ubukhulu bokugcina kwe-grid futhi kuyavumela ukuthi kubhekwe kwezinkulungwane eziningi.

Ukuvumela ukuthenga kwezinkulungwane ngokuvikela ukuthi amandla ayenziwe ngokungafanele ngokusebenzisa ukugcina amandla

Kodwa uma izindawo zokugwala amandla noma izindawo zokuphatha amandla kufuneka zihlale ukuproducisa ngokushesha ngoba umkheli awakwazi ukubambisana konke amandla noma kunezinkinga eziningi zokuphatha, lokhu kuthabatha amandla okanye imali ekhona. Izinhlelo zokugcina amandla zinconywa le ndlela yokuzinikela ngokuthabatha amandla okukhona uma kususwa kwezinye izinhlelo futhi bavulela emuva kumaqhezu lapho abasebenzi badinga amandla angaphezulu futhi bafuna ukulipa izinkambo eziningi. Hlola isibonelo sesikhombiso sokuphatha amandla. Ngemini yezinsuku lapho ilanga libe libalulekile kakhulu, lezi zindawo zizobuka ngokuphakeme kakhulu kunezinto abasebenzi bazokusebenzisa. Ngezinhlelo zokugcina ezifanele, abasebenzi bafunda le amandla okukhona futhi bavulela ku-mkheli ngemini yezinkanyezi lapho ubuningi bakwazi ukubamba futhi izinkambo ziyagcina kakhulu, okuyisibonelo sokuvula imali yabo.

Iziphumo zokufuna imali nezinhlelo zokusebenza ziyahlala kumathathu amabili amakhulu:

• Ukuhlanza imali : Umhlangano wokuqala wokugcina ngokususwa kanye nokuthengiselwa kabusha ukuhlala kwe-$30–$90 kwezinkambo ezingenziwe ngokuphakeme, kusukela kwezinkambo zokuthengiselwa kwezindawo.
• Isilinganiso sesikhundla : Emazweni apho kunezimpilo zokusebenzisa izithombe zokuphila ngokuphelele njenge-California, ukugcina kunciphisa izindleko zokugcina esikhundleni ngama-15–40%.
• Ukunciphisa ukuthwasa : Ukunqoba ukuthwasa kunciphisa ama-0.5–0.8 amathoni we-CO₂ ngamakhilowathi-wati yamahora (MWh) okungasetyenziswa—ukuthuthukisa izinqumo zaseGolide, saseSibonelo naseGolide (ESG) ngaphandle kokuthenga imali engapheleli.

Amaprojekthi athi abhekene nezinkampani zokugcina zibiza ukuvutha okuphakeme ngama-12–25% ngonyaka ngaphandle kokubhekene nezinkampani zokuphila ngokuphelele. Lokhu kubhekene nokuguqula izinto ezinamandla ezingavumelekile kuizinto ezinamandla ezingavumelekile ekufundzeni kwemisebenzi yezindawo zokuthengisa, ukuthuthukisa ukuthengiswa kwezinkampani, ukuthengiswa kwezinkampani, nokuvutha okuphakeme ngokuphelele.

Ukuthuthukisa ukuvutha kwezinkampani zokugcina ngokusebenzisa ukulawula okumangalisayo nokubala okumangalisayo

Izinhlelo zokulawula esiqinisekile zihlaziyela ukugcina amandla kusukela ekubhalekeni kuphela kusukela ekuthinteni imali. Lezi zinhlelo zisebenza ngokuhambisana kwezinto ezenzekayo manje nezithembiso ngokuthi kuzozenzeka noma kuzobhekwa. I-technology entsha yasekhaya iyabonakala kahle kakhulu futhi. Izivakalisi zokufunda ngokwesibonelo (machine learning) zithembisa izindleko zemali nezindlela zokusebenzisa amandla ngaphezu kwe-25% kunezindlela zezinye ezihlukene. Lokhu kusiza isistimu ukuphatha ngokuzimela uma kufanele kugcinwe noma kusukelwe amandla, okuyisiza ukuthola lezi zikhathi zokuthinta izimali ezihlukene. Amasosha ayaphumelela kakhulu kulezi zinhlelo. Ezinsukela ukuthenga amandla angu-45 cents ngakilowatt hour emva kokuthinta kakhulu, bafuna amandla akhe wena. Lokhu kunciphisa lezi zimali ezinkulu zokuthinta okuzocindisela imali ngamunye wezinyanga.

Ama-algorithm ahlakaniphile ayashintsha ngempela uma kuziwa ekutholeni inzuzo engcono ekufakweni kwe-hybrid storage. Ngokwesibonelo, cabanga ngokuxhumana phakathi kokulawula izinga lokushisa nezinhlelo zikagesi. Ukuhlela izinto ngokuhlakanipha kungasheshisa ukupholisa izakhiwo noma kushise amanzi phakathi nalezo zikhathi ezishibhile lapho amandla ehla ngaphansi kuka-8 cents ngekilowatt-hour. Lolu hlelo lubuye lwenze ukulungiswa ngokushesha lapho izibikezelo zelanga zingahambi kahle. Olunye ucwaningo lwamuva mayelana namandla ezakhiwo lwabonisa ukuthi lezi zindlela zokulawula ezakhiwe ngezigaba zandisa ukusetshenziswa kwelanga ngamaphesenti angaba mathathu futhi zinciphisa izikweletu zikagesi ngamaphesenti angaba ngu-8. Okuhlaba umxhwele nakakhulu ukuthi lezi zinhlelo zisebenza kahle kangakanani. Izixazululo eziningi ezisekelwe ku-AI zidla amaphesenti amathathu kuya kwangu-8 kuphela alokho ezisizayo ukukonga, ngakho-ke izilawuli ezihlakaniphile ngokuyisisekelo ziyazikhokhela ngokushesha ezimweni eziningi.

Ukuchazi kwezinkinga zokuphatha kwezindawo zokuphatha ezinamandla kwezinkulungwane zokugcina amandla (Amadla Okuphila, 2025)

Kokugcina, ukuchazi okuphelele ngokuphelele kanye nokuphatha ngokwakho kuvula izindlela zokubhukuda eziyinkulu ngokulingana ne-15–25% kwezinkulungwane zokugcina amandla ngezindawo zokuphila—ngokunika isikhathi eside sokusebenza kwamathuba kanye nokunciphisa izinkinga zokubhukuda kwezindlela zokubhukuda ngokuphelele. Ukuphatha kwezindawo zokusebenza akuyiyo kuphela ukuthuthukisa—kuyiyo indlela eyenzela ukuthi izindlela zokubhukuda zokugcina amandla zihlale kusukela ekupheleni kwezindlela zokubhukuda kuze kuzwakala ukuthi zibhukuda ngokuphelele.
