一种新的网损分摊方法研究

Research on a new loss allocation method

电力市场环境下,不同的网损分摊方法对交易电价有一定影响。提出了一种新的网损分摊方法,即基于交流电气剖分方法。针对普通交流节点分析和推导了分摊到输出流和输入流的网损公式,然后利用电气剖分方法的拓扑关系,将针对交流节点的网损分摊关系推广到网络,无需将有功无功解耦即可求取电力网络中各电源(或负荷)应分摊的网络损耗。算例计算结果表明,该方法合理有效。

Different loss allocation methods affect electric price in electric market. A new loss allocation method is proposed in this paper. Based on electrical dissecting theory, deduction of loss allocation formula for both outputting and inputting flows are made according to normal ac node. And topological relations of electrical dissecting theory are used to extend loss allocation formula of node to the whole network. Loss allocation of each generator or load can be obtained without decoupling the active and reactive power. Results of example show this new method is reasonable and efficient.
