摘　　要：分析揭阳地区电网的基本特点和无功配置情况,针对含分布式电源的地区电网无功优化特点,以有功网损最小为目标,提出了基于纵横交叉算法(CSO)的电力系统无功优化方法。CSO算法中首次提出维局部最优概念和纵横交叉双搜索思想,相比其他主流群智能优化算法,CSO算法在解决维数灾问题和收敛精度方面取得了较大突破。算例仿真结果表明,CSO算法寻优质量高、收敛性好,适合求解大规模系统无功优化问题。Characteristics and the state reactive power configuration of Jieyang power grid are analyzed. According to features of reactive power optimization in district grid with distributed generation, a new kind of algorithm, which is composed of crisscross optimization algorithm（ CSO） is proposed. The CSO algorithm includes horizon cross as well as a vertical cross,whose combining enhances the global convergent ability while the introduction of competitive mechanism drives the potential solutions approximate the global optima in an accelerating fashion without sacrificing the convergence speed.The result of an instance shows that the proposed algorithm has advantages of a high quality solution, good convergence and low computational complexity, which is suited to solve large scale reactive power optimization of a power system.
