摘要
针对配电网运行的辐射型结构 ,在配电网无功优化的无功近似矩模型基础上 ,提出了无功精确矩概念 ,根据无功二次精确矩选择最优补偿点 ,无功一次精确矩确定所应投放的优化容量。本方法在实验系统上进行验证 ,结果表明 :无功精确矩法无论对于降损还是改善电压水平 。
According to the radial structure of the distribution network operation,this paper proposes the concept of reactive accurate moment on the basis of reactive moment model. The optimal placement for capacitors is determined by reactive quadric accurate moment and the optimal sizing by reactive linear accurate moment.It's tested on experimental systems,and the result shows that the reactive accurate moment method is more efficient in both reducing the net loss and improving the voltage profiles than reactive approximate moment.
