IiNkqubo zeHybrid Hydro-PV zandisa iiNzuzo zoMvelisi ukuya kuthi ga kwi-18-21% kwi-Afrika ekwi-Sub-Sahara

Uphononongo olwenziwa ngabaphandi kwiZiko leTekhnoloji yaMandla eNorway luhlalutye ukwenzeka kwe-techno-economic ye-hybridization ye-hypothetical cascade hydropower system kunye ne-photovoltaics edadayo (FPV) kunye ne-photovoltaics efakwe phantsi komhlaba (GPV) phantsi kweemeko zemarike zase-Afrika ezisezantsi kweSahara. Kulolu hlobo lwenkqubo ye-hybrid, i-reservoir enyukayo idityaniswe kwi-reservoir ephantsi, kwaye i-FPVs inokufakwa kwi-reservoir nganye.

"Olu phononongo lujolise ekuqaqambiseni indlela ukusebenza phantsi kwentlawulo esekwe-iwotshi kunye nokwahluka kwamaxabiso amandla kunye nangaphandle kokuzibophelela komthwalo kuchaphazela ubungakanani benkqubo yegridi edityaniswe negridi ye-utility-scale hybrid system," izazinzulu zatsho, ziphawula ukuba ukuxubana kwe-PV ye-PV kunye nombane wamanzi inokuba "yindlela enokwenzeka yokunciphisa ukuguquguquka kwamandla onyaka."

Uphononongo lufumene ukuba inzuzo yomvelisi yonyaka yenkqubo ye-hydro hybridized inyuke nge-18-21% kunye ne-0-4% yesivumelwano sokuthengwa kwamandla amathathu (PPA) kunye neskimu semarike yendawo, ngokulandelelana, xa kuthelekiswa nenkqubo ye-hydro-kuphela kwiimeko zemarike ye-Afrika engaphantsi kwe-Sahara. Kwakhona kwafumanisa ukuba i-hybridization ene-single-axis tracking GPVs ingaba "inketho ye-techno-economically enokwenzeka ngakumbi xa kuthelekiswa nenkqubo ye-FPV" ngenxa ye-capex ephantsi kunye nesivuno esiphezulu samandla e-GPV.

"Ngaphezu koko, kuqikelelwa ukuba i-capex ye-FPV kufuneka ibe malunga ne-42-57% ephantsi kune-PV (GPV) ephantsi komhlaba kunye nokulandelela i-axis enye ye-hydro-FPV inkqubo yokufikelela kwinzuzo yomvelisi wonyaka njengenkqubo ye-hydro-GPV," abaphandi bachaza.

Basekwe kuqikelelo lwe-techno-economic kuzo zombini iinkqubo ze-FPV kunye ne-GPV kuqikelelo oluvela kwiSebe le-US leSizwe laMandla aMandla oMbane oHlaziywayo lweLebhu yeLebhu yeLabhoratri yeSizwe yokuHlaziywa kweendleko zokujonga iinkqubo ze-PV, kunye neendleko zenkunzi kunye neendleko zokusebenza ezisisigxina ezinxulumene nenkqubo ye-hydro ekhoyo ithathwa njengeendleko ezitshisiweyo. Ukulungiselela amagalelo emeko yemarike yamandla, eli phepha lisebenzise idatha yexabiso lemarike ye-Southern African Power Pool (SAPP) ukusuka ngo-2014 ukuya ku-2021.

I-case study iphinda ithathele uqhagamshelo lwenkqubo engumxube kunye negridi yesizwe, kunye nemveliso yamandla ephezulu ye-126 MW. Ukongeza, iphepha liphakamisa "imodeli yenkqubo elungelelanisiweyo yokulinganisa / ukucwangciswa kwenkqubo ye-hydro-FPV edibeneyo."

Ngexesha lonyaka wemozulu eyomileyo, ukuxutywa kwezityalo ze-hydro kunye ne-FPVs kunokubuyisela imveliso yombane ocuthiweyo, okukhokelela ekunyukeni kwe-4% kwingeniso yonyaka yabavelisi. Kwiminyaka yemozulu emanzi, nangona kunjalo, ukuxutywa kwesityalo se-hydro kunye ne-FPV akuzange kubonwe ukuba kuyenzeka ngokwezoqoqosho, ngelixa kwiminyaka ephakathi, kuphela ukunyuka okungafanelekanga kwingeniso yomvelisi yonyaka (ngaphantsi kwe-0.1%) kunokufezekiswa, ngenxa yemida yomthamo wegridi kwikhono lokuba i-FPV ithathe inxaxheba kwimarike yendawo ngexesha leeyure zexabiso eliphezulu. "Ngaphezu koko, inkqubo ye-hydro-GPV ibonwa ukuba ivelise inzuzo ephezulu yomvelisi wonyaka xa kuthelekiswa nenkqubo ye-hydro-FPV kuzo zonke iimeko ezihlalutyiweyo (malunga ne-13-18%)," iphepha laphawula.

Iziphumo ziyafumaneka kwingxelo "Ubuchwephesha boqoqosho lweenkqubo ze-hybrid hydro-FPV kwi-Sub-Saharan Africa phantsi kweemeko ezahlukeneyo zentengiso," epapashwe Umoya ovuselelekayo.

“Iziphumo ziqaqambisa ifuthe lezicwangciso zentengiso ezahlukeneyo kunye neminyaka eyahluka-hlukeneyo yemozulu kwindlela yokwahlula-hlula nokusebenza kwayo. Nangona kunjalo, kwimodeli yexesha elide, ukuqina kweziphumo kunokuphuculwa ngokubandakanya iindlela zokuphucula i-stochastic kuhlalutyo lwe-techno-economic lweenkqubo ze-hybrid-FPV, "baphetha abaphandi.
