动态规划法在供电系统无功优化中的应用

Dynamic Programming Approach to Reactive-power Optimization in a Power Supply System

针对辐射状供电系统,提出了应用动态规划法综合求取有载调压变压器分接头、配电站电容器和馈线电容器的控制策略的数学模型,自动实现电压控制和无功功率优化,并满足控制调节次数的约束。计算结果表明该方法较好地解决了动态规划方法计算量大及结果不精确的问题,有效性及实用性较高。

Aiming at radial power supply systems,the use of dynamic programming approach is proposed to comprehensively solve the mathematical model of control strategy for taps of on-load tap-changing transformers,distribution station capacitors and feeder capacitors,thus realizing automatic voltage control and reactive-power optimization,and meeting the restrictions on control number.Computational results show that the proposed method can greatly settle the huge calculation and inaccuracy problems of dynamic programming approach and is of high validity and practicality.
