摘 要： 介紹了電網(wǎng)無功優(yōu)化的基本原則及方法，分析了電力系統(tǒng)無功優(yōu)化多變量、多約束、非凸非線性的特性，建立了網(wǎng)損最小、兼顧電壓穩(wěn)定性和設(shè)備費用的目標函數(shù)。采用人工智能方法中的禁忌搜索法及其改進算法，利用IEEE30 節(jié)點模型編制程序，針對某一確定時刻的系統(tǒng)進行無功優(yōu)化，結(jié)果表明，該方法明顯提升了電網(wǎng)的經(jīng)濟效益。
關(guān)鍵詞： 無功優(yōu)化；禁忌搜索法；電壓質(zhì)量；有功網(wǎng)損

Abstract: Introduction was made to the basic principles and methods of reactive power optimization. Analysis was made to thefeatures of reactive power optimization, such as multi-variable, multiple-constraint, non-convex and nonlinear. This paper builtthe target function with minimum grid losses, which made a compromise between the quality of voltage and the cost of device.The tabu search method in artificial intelligence and its improved algorithm were adopted and the IEEE30 node model was used to program, so as to carry out reactive power optimization for the system at certain definitive time. The results show that this reactive power optimization method can upgrade the economic effectiveness of grid.
Key words: reactive power optimization; tabu search method; voltage quality; active power losses
