推导了一种负荷对线路潮流贡献分量的新算法。在分析系统无功生产成本构成的基础上,根据边际成本理论将无功生产成本分配给电网各线路,再根据负荷对线路的无功使用份额将各线路分担的无功生产成本分配给各个负荷,从而得出了各负荷分担的无功生产成本和相应的无功价格。该方法在确定负荷对线路无功使用份额时计及了P-Q间的耦合作用,无需任何假设或近似。不仅能够确保收支平衡,而且能为用户提供有效的经济信号。仿真结果验证了该方法的合理性和有效性。
A new algorithm of load contribution to line flow is derived. On the basis of analyzing the composition of the reactive power production cost, the reactive power production cost is distributed to each line of the power grid according to the marginal cost theory, and then the reactive power production cost allocated to each line is allocated to each load , And then draw the reactive power production costs and reactive power prices corresponding to each load. This method accounts for the coupling between P-Qs when determining the share of reactive load on the line and does not require any assumptions or approximations. Not only to ensure that the balance of payments, but also to provide users with a valid economic signal. Simulation results verify the rationality and effectiveness of the method.
