摘 要: 介紹了內(nèi)點(diǎn)法的分支原對(duì)偶路徑跟蹤法,并針對(duì)某區(qū)域電網(wǎng)的無功電壓現(xiàn)狀,建立以網(wǎng)損最小為目標(biāo)函數(shù),并兼顧電壓質(zhì)量最好進(jìn)行無功優(yōu)化,有效降低了系統(tǒng)的有功網(wǎng)損,同時(shí)電壓質(zhì)量也得到提高。該優(yōu)化方法對(duì)于大規(guī)模電網(wǎng)的無功優(yōu)化具有一定的指導(dǎo)意義。
關(guān)鍵詞: 無功優(yōu)化;有功網(wǎng)損;原對(duì)偶路徑跟蹤法;改進(jìn)內(nèi)點(diǎn)法

Abstract: Introduction was made to the branch primal-dual path tracking method of interior point method. Aiming at reactive voltage present state of a local grid, this paper established the objective function with the minimum network loss for reactive power optimization in concurrent of best voltage quality carrying out reactive power optimization to effectively reduce active network loss of the system. The optimization method for reactive power optimization of large-scaled grid has certain guiding significance.
Key words: reactive power optimization; active power loss; primal-dual path following method; improved interior point method
