摘　　要：针对分布式风电(distributed wind generation,DWG)、光伏电池(photovoltaic,PV)等间歇性分布式电源(distributed generation,DG)输出功率的随机性以及负荷的不确定性。采用机会约束规划方法,以间歇性DG与补偿电容的投资支出、售电收益、系统降损收益、电压质量以及废气减排量综合效益为目标函数,建立间歇性DG与补偿电容的综合最优配置模型,并选择遗传算法进行最优求解。算例结果表明,其综合最优方案能提高节点电压期望水平及其处于正常范围内的概率,实现了经济效益、环境效益以及电压质量的综合最优,验证了所建模型的合理性和有效性。The output power of intermittent distributed generation （DG） such as distributed wind generation （DWG） and photovoltaic （PV） is random and the load is uncertain. Aiming at the investment expenses of intermittent DG and compensation capacitor, income of electricity sale, reduction of system power loss, voltage quality and emission reductions, the optimal configuration models of intermittent DG and capacitor were built using chance constrained programming method. Genetic algorithm was chosen for the optimal solution. The simulation results show that the comprehensively optimized allocation model has improved expected value of node voltage and the probability within normal range. The comprehensive optimization of economic benefit, environ-mental benefit and voltage quality were achieved, and the rationality and availability of the proposed model is verified.
