2、的接入方案也越來(lái)越引起重視。通過(guò)分析風(fēng)電場(chǎng)并入配電網(wǎng)后對(duì)其線損影響以及風(fēng)電場(chǎng)在電力系統(tǒng)中的等值模型,以減小螯個(gè)配電網(wǎng)線損為目的,利用最優(yōu)潮流方法,探討了風(fēng)電場(chǎng)并網(wǎng)的最佳地點(diǎn)和最佳容量。最后以IEEE12節(jié)點(diǎn)模型為基礎(chǔ)PSASP上搭建了仿真模型通過(guò)PSASP計(jì)算風(fēng)電場(chǎng)的不同并網(wǎng),在,并點(diǎn)對(duì)配電網(wǎng)線損的影響。研究結(jié)果有助于制定合理的風(fēng)電接入方案,提高含風(fēng)電配電系統(tǒng)的經(jīng)濟(jì)效益。關(guān)鍵詞:風(fēng)電場(chǎng);配電網(wǎng);線損TM7-_-中圍分類號(hào)15文獻(xiàn)A文:16737598201401002205:標(biāo)志碼:章編號(hào)()?—?ImpactofWindPowerI
