摘要/Abstract

摘要： 近年来电力电子装置的广泛应用引起了谐波污染。如果直接对电力系统进行无功优化,谐波频率下容易产生系统与电容器之间的谐振或谐波放大,使系统的谐波畸变率大为增加,破坏系统的安全运行。针对这一问题,提出了计及谐波电压畸变的无功优化模型;在网损最小的基础上,将各节点基波电压和总谐波畸变率越限情况以惩罚项的形式加入目标函数中,将改进萤火虫算法（IGSO）应用到无功优化中,给出基于IGSO计及谐波电压畸变的无功优化具体步骤。通过对IEEE 30节点算例的仿真分析,验证本方法的可行性和优越性,在减小网损和总谐波畸变率的同时,提高了收敛速度和计算精度。

Abstract: In recent years, power electronic devices have been widely used and caused harmonic pollution. If the power system is optimized directly under the harmonic frequency, the harmonic resonance or harmonic amplification between the system and the capacitor is apt to occur, which will lead to increase of harmonic distortion and damage the safety operation of the power system. A mathematical model of reactive power optimization is proposed with consideration of harmonic voltage distortion. Based on the minimum network loss, the fundamental voltage and the total harmonic distortion over the limit of each node were added to the target function by the form of penalty terms and the improved glowworm swarm optimization(IGSO) was applied to reactive power optimization. The specific procedures for reactive power optimization based on IGSO and harmonic voltage distortion are given in this paper. A simulation of the IEEE 30-bus case was conducted to test the feasibility and the superiority of this method. The results of this optimization show that this method reduces the network loss and total harmonic distortions, and has a better convergence efficiency and a higher computational precision.

Key words: reactive power optimization, improved glowworm swarm optimization(IGSO), harmonic amplification, harmonic distortion
