基于边际网损系数法的发电权交易网损分析

Generation Rights Trade Loss Analysis Based on Marginal Loss Coefficient Method

针对边际网损系数法受平衡节点制约和网损系数负值的缺点进行修正,基于此法对发电权交易引起的网损变化进行分析,得到交易网损矩阵,对由于发电权交易所产生的网损计算具有实际指导意义。以IEEE14节点系统和陕西电网为算例,验证了该方法的正确性和通用性。

The marginal loss coefficient method subject to the balance node constraint and the defect of network loss coefficient negative values are modified in this paper, on the basis of this method the network loss changes caused by the generation fight trades are analyzed so as to obtain the trade network loss matrix, being of the practical guidance significance for network loss calculation produced by the generation fight trade IEEE14 bus system and Shaanxi power grid expanples are used to test the correctness and uni- versality of this method.
