1、第40卷第7期電力系統(tǒng)保護(hù)與控制Vl01.40NO.72012年4月1日PowerSystemProtectionandControlApr.1,2012基于黃金分割的混沌粒子群優(yōu)化算法在配電網(wǎng)無功規(guī)劃中的應(yīng)用汪超,王昕,姚鋼,鄭益慧,周荔丹2,劉鑫(1.上海交通大學(xué)電工與電子技術(shù)中心,上海200240;2.上海交通大學(xué)電氣系,上海200240;3.吉林省電力有限公司四平供電公司,吉林四平136000)摘要:首先以有功損耗功率最小作為目標(biāo)函數(shù),將節(jié)點(diǎn)電壓越限和發(fā)電機(jī)無功出力越限作為罰函數(shù),建立無功補(bǔ)償在配電網(wǎng)中優(yōu)化配置的數(shù)學(xué)模型。然后設(shè)計(jì)基于黃金分割的混沌
2、粒子群優(yōu)化算法對(duì)上述模型進(jìn)行求解。該算法通過黃金分割評(píng)判準(zhǔn)則,按照適應(yīng)度的高低,將粒子群分成標(biāo)準(zhǔn)粒子和混沌粒子兩部分,同時(shí)解決了粒子群優(yōu)化過程中容易陷入局部最優(yōu)和混沌算法重復(fù)搜索部分解的問題,從而可以更有效地搜索到全局最優(yōu)解,成功地提高了無功優(yōu)化問題的求解速度,使算法能更好地適應(yīng)問題的求解。算例結(jié)果表明,該方法技術(shù)上可行且效果較好。關(guān)鍵詞:配電網(wǎng);無功優(yōu)化;黃金分割;混沌;粒子群算法Applicationofgoldensectionbasedchaosparticleswarmoptimizationalgorithmindistributionnetw
