多目标电力系统无功优化及其方法

在无功优化问题中,所追求的目标往往不只一个,各目标之间还可能相互矛盾,多目标规划方法正是解决此类问题的方法之一。为便于掌握多目标规划方法及其应用,分析比较了目标函数加权求和法、最小目标偏差法、最大满意度法、距离函数法等几种常用多目标规划模型及其特点,讨论了多目标规划解的性质,在此基础上提出混合优化方法实现多目标无功优化应用,并通过计算实例证明了算法的有效性和实用性。

MultiObjective Reactive Power Optimization and Its Approaches

In the reactive power optimization, there is used to be several objectives and each objectives are in mutual contradiction. Multiobjective programming can solve this kind of problem. Several multiobjective programming models most in common use such as the approach of objective function weightedsum, of minimum objective deviation, of maximum coincident scale, of distance function are analyzed in comparison. The properties of the resolutions of the multiobjective programming are discussed. On the base in hybrid optimization approach is proposed to the reactive power optimization. The effectiveness and realization are proved by case studies.
