2、電網(wǎng)運行狀態(tài)的改變,通過改變改進Delphi法的指標權(quán)重值調(diào)整綜合指標的組成。模型求解時,先對目標函數(shù)進行無量綱化處理,再采用混沌變異的粒子群算法得出DG最優(yōu)配置方案。通過算例IEEE一33母線節(jié)點系統(tǒng)表明,提出的優(yōu)化目標函數(shù)滿足不同運行狀態(tài)下的優(yōu)化要求,能有效地改善系統(tǒng)的運行條件,提高系統(tǒng)運行的安全性和經(jīng)濟性。關(guān)鍵詞:分布式電源;優(yōu)化配置;運行風(fēng)險;指標權(quán)重;改進德爾菲法;粒子群優(yōu)化中圖分類號:TM734文獻標志碼:A文章編號:1003—8930(2016)03—0018—05DOI:10.3969~.issn.1003-8930.2016.03.0
