Ukugcinwa kokulawula imvamisa kubhekisela emandleni esistimu yokugcina amandla (ESS) noma ezinye izinsiza eziguquguqukayo ukuphendula ngokushesha ekuguquguqukeni kwefrikhwensi yegridi kagesi. Kusistimu yamandla kagesi, imvamisa iyipharamitha ebalulekile edinga ukugcinwa ngaphakathi kwebanga elithile (ngokuvamile i-50 Hz noma 60 Hz) ukuze isistimu isebenze kahle nangokuphepha.
Uma kukhona ukungalingani phakathi kokuphakelwa kukagesi kanye nesidingo kugridi, ifrikhwensi ingaphambuka enalulweni yawo yokulinganisa. Ezimweni ezinjalo, ukugodla kokulawula imvamisa kuyadingeka ukuze kujove noma kuhoxiswe amandla kugridi ukuze kunziswe imvamisa nokubuyisela ibhalansi phakathi kokunikezwayo nokufunwa.
Uhlelo Lokugcina Amandla
Amasistimu okugcina amandla, njengokugcinwa kwebhethri, afaneleka kahle ekuhlinzekeni ngezinsizakalo zokuphendula imvamisa. Uma kunogesi oweqile kugridi, lezi zinhlelo zingamunca ngokushesha futhi zigcine amandla asele, zinciphise imvamisa. Ngokuphambene, lapho kukhona ukushoda kukagesi, amandla agciniwe angakhishwa emuva kugridi, okwandisa imvamisa.
Ukuhlinzekwa kwezinsizakalo zokuphendula imvamisa kungaba yinzuzo ngokwezimali kumaphrojekthi we-ESS. Abasebenzi begridi bavame ukukhokhela abahlinzeki bezinqolobane zokulawula imvamisa ngenxa yekhono labo lokuphendula ngokushesha futhi basize ukugcina ukuqina kwegridi. E-Europe, imali engenayo etholakala ngokuhlinzeka ngezinsizakalo zokuphendula imvamisa ibe umshayeli obalulekile wokusatshalaliswa kwamaphrojekthi okugcina amandla.
Isimo Semakethe Yamanje Sokuphendula Imvamisa
Kodwa-ke, njengoba amaphrojekthi amaningi e-ESS engena emakethe, imakethe yokuphendula imvamisa ingase igcwale, njengoba kuqokonyiswe yi-Bloomberg New Energy Finance. Lokhu kugcwala kungase kube nomthelela emandleni emali engenayo evela ezinsizeni zokuphendula imvamisa. Ngakho-ke, amaphrojekthi okugcina amandla angase adinge ukuhlukanisa imithombo yawo yemali engenayo ngokunikeza ezinye izinsizakalo, njenge-arbitrage (ukuthenga ugesi lapho amanani entengo ephansi futhi adayise lapho amanani entengo ephezulu) kanye nezinkokhelo zamandla (inkokhelo yokuhlinzeka amandla kugridi).
Amathrendi wemiklamo ye-Future Energy Storage
Ukuze ahlale esebenza kahle kwezomnotho, amaphrojekthi okugcina amandla angase adinge ukuthi asuse ukugxila kwawo ezinsizakalweni zokuphendula imvamisa yesikhathi esifushane aye kumasevisi esikhathi eside angangenisa imali engenayo ezinzile futhi esimeme. Lokhu kushintsha kungase kuqhubekisele phambili ukuthuthukiswa kwamasistimu okugcina amandla akwazi ukunikeza amandla isikhathi eside futhi anikeze ububanzi obubanzi bezinsizakalo zokusekela zegridi ezingaphezu kwesabelo sokulawula imvamisa.
Hlala ubukele ukuze uthole imininingwane eyengeziwe yemakethe, izixazululo ezintsha, namathrendi embonini evela e-Dowell. Masiqhubeke nokufunda, sikhulise, futhi silolonge ikusasa lomkhakha wokugcinwa kwamandla!
