基于线性规划算法的配电网无功补偿优化规划

摘要

无功补偿优化规划在配电网规划设计中主要考虑的优化目标网损最小、投资最省、综合经济效益最大等。对不同的目标，采用不同的无功配置规划。文中建立了针对配电网络的线性规划求解法的数学模型，以综合经济效益最大为目标函数，以无功平衡、电压为约束条件，结合无功潮流的最优化，计算出运行参数后通过多次迭代计算可获得最佳无功优化。%As the optimization of reactive power compensation plays a key role in planning and design of the distribution network, the chief considerations of optimization targets are the minimum transmission loss ,the minimum investment and the maximum overall economic efficiency, adopting different reactive configuration planning according to different targets. A mathematical model is built in accordance with linear programming method of distribution network. It makes the maximum overall economic efficiency as the objective function, takes reactive power balance and voltage qualification as constraints and combines the optimization of reactive power flow. Through repeatedly using the iterative method after calculating the operating parameters, we obtain reactive power optimization.
