A Grid Loss Allocation Method Based On Imputation Components Of Dissipation Power

At present,the power industry is undergoing profound worldwide innovation. Different countries promote the power industrialization of market-oriented for different reasons and ways.The construction of China's power market has not become mature yet, there are many problems to be solved,including the loss allocation problem.The effect of different loss allocation methods to market participants is different.Therefore,to explore a fair, reasonable and scientific network loss allocation method is one of the important issues in the process of current power market innovation. It is also of great significance to improve power system efficiency and to ensure healthy development of the power market.Loss allocation in-depth from circuit theory and economics theory is discussed in this paper.The research background and significance of loss allocation are described in this paper as well as research status of loss allocation methods.The basic principles which loss allocation methods should satisfy are analyzed.The typical domestic and abroad power market operation modes and loss allocation methods used are studied.Classic power losses allocation methods existing and characteristics of the basic principles are discussed.On this basis,from the circuit theory, a loss allocation method using imputation components of dissipation power is proposed.At first, sources are represented by Thevenin model and loads impedance. And then the imputation part of branch dissipation power to each source is calculated by using imputation components of dissipation power. It is the loss allocation caused by a certain source to sum its component of dissipation power on each branch. Finally,the loss is allocated proportionally to that source and all loads supplied from it.This method meets all the circuit laws,and makes all the network loss allocated to all consumers and generators, and takes into account the interactions between active and reactive powers.IEEE 14-bus system simulation results demonstrate that this method is suitable for any scale, any structure and any operating mode of the loss allocation, but also can ensure fair and equitable loss allocation.
