考虑到非线性负荷所产生的谐波电流具有随机性 ,首次将供用电网络中各节点谐波电压的综合抑制转化为机会约束规划问题 ,采用基于随机模拟的遗传算法 ,以有源滤波器总投资最小为目标 ,给出了它们的安装地点及容量的优化方法 ,并用实例说明了本算法的有效性。

Considering the randomness of harmonic current caused by nonlinear loads in distribution networks. a chanceconstrained programming approach is first proposed in this paper to mitigate the harmonic voltage distortion by optimallyallocating the active power filters with minimum investment. The approach is to get the solution by a random simulationbased genetic algorithm. The locations of the active power filters and the optimal method for their capacity are given. Theresults on a distribution system are given to illustrate the effectiveness of the method.
