配电网络无功补偿的优化模型与算法

Optimized Model and Algorithm to Reactive Power Compensation of distribution Net works

提出了配电网络无功补偿的优化模型， 它以年总支出费用为目标函数， 以潮流方程和运行限量作为约束条件， 并采用罚函数和变尺度法来求解这一非线性规划问题. 这一优化模型是充分考虑配电网的特点和实际运行条件而作出的综合优化模型.

This paper presents an optimized model of reactive power compensation of distribution networks in power systems, in which the minimum of annual cost i s taken as the objective function and the power flow equations and the operation limits are taken as constraints. The nonlinear problem is solved by penalty fun ction by means of Davidon-Fletcher-Powell Method. The optimized model is establi shed in consideration of the practical operations of the distribution networks.
