在全球范圍內(nèi),絕大多數(shù)人口主要依賴對(duì)環(huán)境有破壞作用的化石能源,如煤、石油、天然氣(等。為了開發(fā)清潔的替代能源,很多國家開始研究以風(fēng)能為代表的可再生能源,并將其與現(xiàn)有發(fā)電系統(tǒng)相結(jié)合。對(duì)風(fēng)-光-水互補(bǔ)發(fā)電系統(tǒng)進(jìn)行了仿真研究,以尋找解決巴基斯坦工業(yè)負(fù)荷較大這一難題的發(fā)電方案。該系統(tǒng)已在美國國家可再生能源實(shí)驗(yàn)室（NREL）開發(fā)的HOMER（多種可再生能源互補(bǔ)和分布式發(fā)電系統(tǒng)）軟件包中實(shí)現(xiàn)。對(duì)5個(gè)系統(tǒng)案例進(jìn)行分析,分別為:（1）風(fēng)-光-水發(fā)電系統(tǒng)、（2）風(fēng)-水發(fā)電系統(tǒng)、（3）光-水發(fā)電系統(tǒng)、（4）水發(fā)電系統(tǒng)、（5）電網(wǎng)系統(tǒng)。研究表明,與現(xiàn)有的電網(wǎng)系統(tǒng)相比,風(fēng)-光-水互補(bǔ)發(fā)電系統(tǒng)降低了 42.85%的電費(fèi),并將電網(wǎng)能耗降低到33.98%,因此該系統(tǒng)成本最低。此系統(tǒng)可再生能源占比可達(dá)6 6%。該系統(tǒng)可通過增加可再生能源份額以降低電網(wǎng)中傳統(tǒng)能源的比重,減少國家對(duì)化石能源的依賴,從而減少化石經(jīng)濟(jì)效應(yīng)。該系統(tǒng)發(fā)電不僅可以通過出口增加國內(nèi)生產(chǎn)總值,還有助于解決巴基斯坦能源短缺問題,促進(jìn)巴基斯坦工業(yè)發(fā)展和經(jīng)濟(jì)增長(zhǎng)。
