Amandla-kuya-ukushisa-kuya-emandleni isitoreji se-PV esophahleni

Ososayensi e-Spain bahlole ukusebenza 'kwesitoreji samandla-kuya-ukushisa-kuya-kumandla' endaweni yokuhlala yokufakwa kwelanga e-Madrid.Ubuchwepheshe bunganciphisa izikweletu zikagesi ngaphezu kuka-70% futhi buzoba nesikhathi sokukhokha seminyaka engu-12 kuya kwengu-15, ngokusho kwabacwaningi.

Abacwaningi e-Polytechnic University of Madrid bahlole ukuthi kungenzeka yini ukugcina amandla akhiqizwe i-solar ephezu kophahla njengokushisa okungase kusetshenziselwe ukukhiqiza amandla lapho ilanga lingakhanyi - 'isitoreji samandla okushisa-kuya-kumandla,' noma Ubuchwepheshe be-PHPS.

Uhlelo lwasendlini eMadrid olwenziwa ososayensi lwaluhlanganisa olusebenza kahle kakhulu,iphampu yokushisa eqhutshwa ngokushisanabaqoqi be-solar thermal.

Isistimu ye-'trigeneration', noma ubuchwepheshe obuhlanganisiwe bokupholisa, ukushisisa namandla (CCHP) buhlanganisa izinhlobo ezimbili zesitolo sokushisa: ephansi noma ephakathi nendawo yamanzi ashisayo asekhaya kanye nokushisisa isikhala kanye nesitolo sokushisa esisezingeni eliphezulu sokushisa okuhlangene namandla. isizukulwane.Ukushisa okukhiqizwa ekuqaleni kungasetshenziselwa ukupholisa kanye nesidingo sokushisisa.

Ikesi eliyireferensi lalisekelwe ekusetshenzisweni kwamandla egridi kanye nephampu yokushisa eqhutshwa ngogesi yokupholisa.

Iqembu laseMadrid lithe izinto ezihlanganisa neizindleko zamandla egridi nophethilolikanye nentengo nokukhiqiza kwezinhlaka ze-PV kungaba nomthelela kusayizi ophelele wezinhlelo zokuphindaphinda kathathu.Abacwaningi balinganisela izindleko ezingu-€900-1,200/kW zezinhlelo ze-PV futhi basekelwe isilinganiso sabo senzuzo ye-PHPS ekongeni kukagesi okuwumphumela.

Uhlelo lokugcina amandla okushisa kuya kumandla wasekhaya lungashayela ukonga ugesi wegridi ngaphezu kuka-70%, ngokusho kwabacwaningi, kodwa kuzodinga iminyaka engu-12-15 ukuzikhokhela."Lokhu kuyiqiniso ngisho nalapho ukuguqulwa kokushisa kuya kwamandla [ukusebenza] kuphansi ngokumaphakathi (20-30%), inqobo nje uma izimo zomnotho zivuma," kusho abacwaningi.

Iqembu laseMadrid livumile ukulahlekelwa ukushisa esitolo esishisayo esisezingeni eliphezulu kungasho ukuthi uhlelo lwe-PHPS luzosho izinga lokusebenzisa amandla elanga angama-40-60 kuphela."Izindlela ezingenzeka zokunciphisa lokhu kulahlekelwa zifaka ukuthuthukiswa kwenoveli, izitolo zokushisa eziminyene kakhulu emazingeni okushisa aphansi ngokusesilinganisweni, noma ukufakwa kwe-thermal okuthuthukisiwe [amasistimu]," kwengeza abacwaningi.

Okutholwe yiqembu kuchazwe ocwaningweniUkuhlaziywa kwe-Techno-economic ye-solar PV amandla-kuya-ukushisa-kuya-kumandla wokugcina kanye nokukhiqizwa kwe-trigeneration endaweni yokuhlalar,ishicilelwe kuAmandla Asetshenziswanakuwebhusayithi yeScienceDirect.
