摘要
文中提出一种基于戴维南模型和耗散功率转归分量的损耗分摊方法。该方法先将电源等值成戴维南模型,将负荷等值成阻抗,再运用耗散功率转归分量确定各支路耗散功率转归给各个电源的部分。总加某电源在电网所有支路上的耗散功率分量得该电源引起的电网损耗。最后将该损耗按比例分配给该电源和由它供电的所有负荷。文中方法满足电路定律、计及有功和无功潮流的交叉耦合,使所有电源和负荷都参与损耗分摊,具有公平合理和易于实施的特性。仿真结果验证了文中方法的有效性和可行性。
A loss allocation method using Thevenin model and imputation components of dissipation power was proposed.In the method,the power source is represented by Thevenin equivalent model and load by equivalent impedance.Imputation part of branch dissipation power to each source is calculated by using imputation components of dissipation power.Total network loss allocation caused by a certain source is obtained by summing its component of dissipation power on each branch and allocated proportionally to that source and all loads supplied from it.This proposed method meets all the circuit laws,and takes into account the interactions between active and reactive powers,and makes all the network losses allocated to all consumers and generators,which make loss allocation fair and reasonable.Simulation results verified its effectiveness and feasibility.
