Imakethe yasekhaya yokugcina amandla ezimboni kanye nezohwebo ikhula ngokushesha. Kodwa-ke, ukuqinisekisa ubuhlakani, umnotho, nokuphepha kokwakhiwa kwephrojekthi yokugcina amandla kudinga ukuqonda okujulile kwesistimu yokugcina amandla kanye nenqubo yokuklama neyokwakha. Ukuze unikeze isiqondiso esithile, izinkinga ezivamile ekwakhiweni nasekwakhiweni kwezinhlelo zokugcina amandla ezimbonini nezohwebo zifinyezwa ngezansi.

Elinye lamanani abalulekile okusetshenziswa kwezinhlelo zokugcina amandla ezimboni nezohwebo i-peak-valley arbitrage. Ngokuthatha ithuba lomehluko wamanani phakathi kwamazinga kagesi aphezulu kanye ne-valley, lezi zinhlelo zingashaja ngezikhathi zesidingo esiphansi futhi zikhishwe ngezikhathi ezidingeka kakhulu, zehlise ngempumelelo izindleko zikagesi webhizinisi. Esinye isicelo ibhalansi yokufunwa kukagesi izikweletu. Amasistimu okugcina amandla angasiza ukusika iziqongo nokugcwalisa izigodi, asuse imithwalo ephezulu futhi enze bushelelezi ijika lokusetshenziswa kwamandla, ekugcineni kwehle izikweletu ezidingekayo zikagesi.

Ngaphezu kwalokho, izinhlelo zokugcina amandla ezimboni nezohwebo zinikeza ukunwetshwa kwamandla ashukumisayo. Ngokuvamile, umthamo we-transformer wabasebenzisi ulungisiwe, futhi lapho umsebenzisi edinga ukulayisha ngokweqile i-transformer isikhathi esithile, ukukhuliswa kwamandla kuyadingeka. Kodwa-ke, ngokufaka uhlelo lokugcina amandla oluhambisanayo, umthwalo we-transformer ungancishiswa ngokusebenzisa ukugcinwa kwamandla nokukhishwa phakathi nalesi sikhathi, okuholela ekongeni kwezindleko ngokugwema isidingo sokunwetshwa komthamo we-transformer. Ukwengeza, amasistimu okugcina amandla anika amandla impendulo yohlangothi lwesidingo. Njengoba amasistimu anjalo ekhona, amakhasimende awasadingi ukukhawulela amandla noma akhokhe izikweletu zikagesi eziphezulu ngesikhathi sokuphendula isidingo. Esikhundleni salokho, bangabamba iqhaza ekuphenduleni kokufunwa ngamandla ngesistimu yokugcina amandla futhi bathole izinkokhelo zesinxephezelo ezengeziwe.

Mayelana namamodeli okutshalwa kwezimali, kunezinketho ezimbili eziyinhloko zezinhlelo zokugcina amandla ezimbonini nezohwebo: ukuphathwa kwamandla kwenkontileka kanye nokuzitshalwa kwezimali komnikazi. Kumodeli yokuphatha amandla enkontileka, abatshalizimali bamandla batshala imali ekuthengeni nasekwakheni amasistimu okugcina amandla, bese besayina izivumelwano zesevisi yamandla nezinkampani ezisebenzisa amandla ukuze babelane ngezinzuzo. Isilinganiso sokwabelana phakathi kwabatshalizimali bamandla nezinkampani ezisebenzisa amandla ngokuvamile silandela ingxenye, efana no-90%:10% noma 85%:15%. Ngakolunye uhlangothi, imodeli yokutshalwa kwezimali komnikazi ibandakanya amabhizinisi adla ugesi atshale imali ngokuzimela ekuthengeni amasistimu okugcina amandla kanye nokuthola zonke izinzuzo ekutshalweni kwawo.

Ukuze zifaneleke ukufaka iziteshi zikagesi ezigcina amandla ezimbonini nezohwebo, izinkampani kumele zibekwe ezindaweni ezinomehluko omkhulu wamanani entengo kagesi. Lokhu kungenxa yokuthi umthombo oyinhloko wemali engenayo yalezo ziteshi zikagesi imali engenayo evela kumehluko wamanani aphezulu esigodini. Ukwengeza, isikhathi sokulayisha ugesi webhizinisi kufanele sihlanganise isikhathi esiphezulu, futhi umehluko wentengo ophakathi nendawo ukuya esigodini kufanele ubonakale (ngokuvamile ngaphezu kuka-0.7 yuan/kWh). Kubalulekile futhi ukuthi kube nomthamo owanele osele ku-transformer phakathi nesigodi nezikhathi eziyisicaba zokusetshenziswa kwamandla ebhizinisi ukushaja isistimu yokugcina amandla. Ngaphezu kwalokho, izinkampani ezinezinsuku ezimbalwa zokuvala zokulungisa kanye nesizini zifanelekile, njengoba isikhathi sonyaka sokusebenzisa uhlelo lokugcinwa kwamandla kufanele sibe ngaphezu kwezinsuku ezingama-270 ukuze kuqinisekiswe isivuno esihle.

Ukuze kufakwe iziteshi zamandla okugcina amandla, izinkampani zikagesi zidinga ukuqoqa ulwazi oluthile. Lokhu kufaka phakathi ulwazi oluyisisekelo mayelana nohlobo lokusetshenziswa kukagesi, intengo kagesi eyisisekelo, izikhathi zokusebenzisa, amanani entengo kagesi wesikhathi sokusebenzisa, ukuphela kukagesi webhizinisi kanye nezimo zokukhiqiza. Ukunqunywa kokuqala kokushaja kokwabelana kwesikhathi sokugcinwa kwamandla kanye namasu okuchitha kuncike futhi ekwazini uhlobo lokusetshenziswa kwamandla, izikhathi zokusetshenziswa, nezintengo zikagesi. Ukwengeza, ukuqonda isimo sokukhiqiza senkampani kanye nesikhathi sonyaka sokusetshenziswa kokugcinwa kwamandla kubalulekile. Layisha idatha yokusetshenziswa kwamandla, okuhlanganisa idatha yomthwalo wamandla, isilinganiso sokulayisha/ubukhulu bamandla, namandla e-transformer onyakeni odlule, nakho kuyadingeka. Le datha isetshenziselwa ukubala umthamo wokwakhiwa kwesitoreji samandla ngokusekelwe kudatha yokulayisha namandla e-transformer, kanye nokuklama ukushaja kwesistimu nokukhipha ingqondo yokulawula isikhathi kanye nezibalo zezomnotho zesistimu. Ulwazi oluningiliziwe mayelana nomdwebo oyinhloko wesistimu yamandla, ipulani yesitezi sefekthri, ukwakheka kwegumbi lokusabalalisa, umdwebo wendlela yomzila wekhebula, kanye nesikhala esibekelwe kufanele futhi kuhlinzekwe ukuze kunqunywe indawo yokufaka isistimu yokugcina amandla nokuklama uhlelo lokufinyelela.

Ukubala umthamo wokwakhiwa kwesitoreji samandla ngokusekelwe olwazini lomthwalo wamandla ebhizinisi, kubalulekile ukuqinisekisa ukuthi umthwalo omkhulu ngesikhathi samandla + isikhathi sokushaja isitoreji samandla singaphansi kwama-80% womthamo we-transformer. Lokhu kwenzelwa ukuvimbela ukugcwala ngokweqile komthamo we-transformer lapho kushajwa isistimu yokugcina amandla. Ukwengeza, umthwalo ngesikhathi samahora aphakeme amanani kagesi phakathi nosuku kufanele ube mkhulu kunamandla aphezulu okukhishwa kwesitoreji samandla. Ukuhlinzeka kalula ngedatha yanyanga zonke noma yonyaka yokusetshenziswa kukagesi akwanele ukukhombisa ngokunembile umthwalo kagesi wenkampani wamahora angu-24 nsuku zonke nokubala umthamo wokumisa isitoreji samandla. Kunikezwe isibonelo esinemininingwane, esibonisa ukuthi umthamo we-transformer usuwonke, iphethini yokulayisha ugesi, kanye nenkathi yesikhathi kuwuthinta kanjani umthamo wokwakhiwa kwesitoreji samandla.

Kafushane, njengoba imakethe yasekhaya yokugcina amandla ezimboni kanye neyentengiso iqhubeka nokukhula, kubalulekile ukuqinisekisa ubuhlakani, umnotho, kanye nokuphepha kokwakhiwa kwephrojekthi yokugcina amandla. Ukuqonda amanani ezicelo ahlukahlukene, amamodeli okutshalwa kwezimali, kanye nezimfuneko zokufakwa okufanele kungasiza ukuqondisa ukuklanywa nokwakhiwa kwamasistimu okugcina amandla ezimboni nezohwebo. Ukuqoqa ulwazi oludingekayo kanye nokubala ngokunembile umthamo wokwakha isitoreji samandla ngokusekelwe olwazini lomthwalo wamandla ebhizinisi nakho kuyizinyathelo ezibalulekile zokuqinisekisa impumelelo yokufakwa kwesiteshi sikagesi sokugcina amandla.
