Abstract

一种获取交流电力网中源荷的网损功率分量的对称方法，首先根据交流电力网中节点源荷功率和支路导纳建立节点源荷功率关于节点平移电压和节点电压相位的线性表达式；再据此建立交流电力网稳态的线性对称模型；接着利用M‑P逆矩阵建立全网节点平移电压和节点电压相位关于全网节点源荷功率的线性对称矩阵表达式；然后根据该线性对称矩阵表达式建立网损功率关于全网节点源荷功率的对称代数表达式；最后利用Shapley值定理建立获取源荷的网损功率分量的对称代数计算式，从而实现交流电力网中源荷的网损功率分量的获取。这种源荷的网损功率分量为交流电力网调度中计入网损、保障其运行经济性提供了一种新的高效准确工具。
