Njengoko icandelo lamandla ehlabathi litshintshela kwimithombo yombane ecocekileyo, ezinzileyo, ukuhlanganiswa kwamandla ombane kunye neenkqubo zokugcina amandla (ESS) kuvela njengeqhinga elinamandla. Zombini iitekhnoloji zidlala indima ebalulekileyo ekwandiseni uzinzo kwigridi, ekuphuculeni ukusebenza kakuhle kwamandla, kunye nokuxhasa ukukhula kwemithombo ehlaziyekayo ehlala ihleli njengelanga nomoya. Xa zidityanisiwe, amandla ombane kunye nokugcinwa kwamandla kunokudala inkqubo yamandla eyomelela ngakumbi, eguquguqukayo, nethembekileyo.
Amandla e-Hydropower: uMthombo waMandla aVuselwayo oBonelweyo, oGuquguqukayo
I-Hydropower kudala isisiseko semveliso yamandla ahlaziyekayo. Ibonelela ngeenzuzo ezininzi eziphambili:
Ukubonelelwa ngoMthwalo wesiseko esiZinzile: Umbane owenziwe ngamanzi ombane ubonelela ngokuveliswa kombane okuqhubekayo nokuthembekileyo, nto leyo iyimfuneko ukuhlangabezana neemfuno zomthwalo osisiseko.
Ubuchule bokuphendula ngokukhawuleza: Izityalo zombane wamanzi zinokunyuka okanye zihle ngokukhawuleza ekuphenduleni ukuguquguquka kwemfuno, zizenze zilungele ukulinganisa igridi.
Ubomi obude kunye neeNdleko zokuSebenza eziPhantsi: Ngokulungiswa okufanelekileyo, izibonelelo zombane wamanzi zinokusebenza amashumi eminyaka, zinika ukusebenza okuhambelanayo kunye neendleko eziphantsi komda.
Nangona kunjalo, amandla ombane anokuphenjelelwa lutshintsho lwamaxesha onyaka kubukho bamanzi, kwaye kufuna utyalo-mali olubalulekileyo lweziseko ezingundoqo kunye neemeko ezifanelekileyo zejografi.
IiNkqubo zokuGcinwa kwamandla: Ukuvumela ukuguquguquka kweGridi
Iinkqubo zokugcina amandla, ngakumbi ukugcinwa kwebhetri, zibonelela ngoluhlu lwezakhono ezihambelana nombane:
Ukuzinza kweGridi: I-ESS inokusabela kwi-frequency yegridi kunye nokuguqulwa kwe-voltage kwi-milliseconds, ukuphucula ukuzinza kwenkqubo yonke.
Ukuhlanganiswa kwamandla ahlaziyekayo: Ukugcinwa kuvumela umbane ogqithisileyo ovela kwilanga okanye umoya ukuba ugcinwe kwaye usetyenziswe xa imveliso iphantsi, ukujongana nemiba yokuphazamiseka.
I-Peak Shaving kunye noShifting Shifting: Ngokugcina amandla ngexesha leeyure ze-off-peak kunye nokukhulula ngexesha lemfuno ephezulu, i-ESS inceda ukunciphisa uxinzelelo kwigridi kunye neendleko zamandla eziphantsi.
Ngaphandle kokuguquguquka kwazo, iinkqubo zokugcina amandla zodwa zinokuba nemida kumthamo kunye nobude, ngokukodwa ukugcinwa kwexesha elide okanye ixesha lonyaka.
Isibini esigqibeleleyo: Intsebenziswano phakathi kwe-Hydropower kunye ne-ESS
Xa zidityanisiwe, amandla ombane kunye nokugcinwa kwamandla kwenza ubambiswano lokuqinisa ngokulinganayo. Iimpawu zabo ezihambelanayo zibonelela ngeenzuzo ezininzi zeqhinga:
1. Ukuthembeka kweGridi kunye nokuZinzisa
I-Hydropower ibonelela ngokuzinzileyo, ukubonelela ngesiseko esihlaziyiweyo, ngelixa i-ESS ibamba ngokukhawuleza, ukuguquguquka kwexesha elifutshane. Ngokudibeneyo, bakha amandla okulinganisa amaxesha amaninzi axhasa igridi yamandla ezinzileyo phantsi kweemeko zomthwalo oguquguqukayo.
2. Ukusetyenziswa ngokukuko kwaMandla aVuselelwayo
Iinkqubo zogcino zinokufunxa ukuveliswa kombane ogqithileyo ngamanzi ngexesha lemfuneko ephantsi, ukuthintela ukuchitheka kwamanzi kunye nokwandisa ukusetyenziswa kwamandla. Ngokuchasene noko, ngexesha lokufumaneka kwamanzi aphantsi, amandla agciniweyo anokongeza unikezelo ngaphandle kokunciphisa ukuthembeka.
3. Inkxaso yeeGridi ezikude okanye ezikwaZodwa
Kwiindawo ezingaphandle kwegridi okanye kwiindawo ezikude, ukudibanisa amandla ombane kunye nokugcinwa kwawo kuqinisekisa amandla aqhubekayo naxa ukuhamba kwamanzi kunganelanga okanye kuphakathi. Oku kusekwa kwe-hybrid kunganciphisa ukuthembela kwiijenereyitha ze-diesel kunye nokukhutshwa kwekhabhoni ephantsi.
4. Pumped Storage Hydropower: Esona siGqwesileyo sawo omabini amaHlabathi
Impompo yokugcina i-hydro yingxubevange yendalo yazo zombini iitekhnoloji. Igcina umbane ogqithisileyo ngokumpompa amanzi kwidama eliphezulu ize iwakhulule ukuvelisa umbane xa kuyimfuneko—okuyinyani isebenza njengesisombululo esikhulu, esihlala ixesha elide sokugcina amandla.
Ukuqukumbela
Ukuhlanganiswa kwamandla ombane kunye neenkqubo zokugcina amandla yindlela ekhangele phambili yokwakha ikamva lamandla acocekileyo, athembekileyo. Nangona i-hydropower ibonelela ngokuzinza kunye nesizukulwana sexesha elide, iinkqubo zokugcina zongeza ukuguquguquka kunye nokuchaneka. Ngokudibeneyo, banikezela ngesisombululo esongezelelweyo esonyusa ukhuseleko lwamandla, ukuxhasa ukuhlanganiswa okuvuselelekayo, kunye nokukhawulezisa ukutshintshela kwigridi yamandla ekhabhoni ephantsi.
