Research On Loss Allocation Of Pool And Bilateral Hybrid Transactions

In the electricity market,how to put the transmission loss created during trasmissing process to all market participants in the electricity market fairly,accurately and reasonably is one of the key problem,blut also a basic requirements of the electricity fair market. At present there are a lot of transmission loss allocation methods,but no one can be the parties generally accepted to share.This paper studies the current situation of the development of the electricity market,electricity market transaction model and transmission loss allocation study what are faced with problems and to solve these problems this paper processing methods,this paper analyzes the various transaction models on the transmission loss allocation requests,compared the different transaction models commonly used transmission loss allocation methods and their advantages and disadvantages.The solutions of transmission loss allocation under the pool and bilateral hybrid transaction model is scrutinized in this paper.Power flow tracing method as a transmission loss allocation method faced for the nodes,intuitively describes the trend of the actual physical flow,can accurately reflect the nonlinear system,to make sure that each generator and load of a line of the trend,but this method is only appropriate for the transmission loss allocation of pool models.In this paper based on the allocation in made the improvement,to suit the transmission loss allocation under the pool and bilateral hybrid transaction,this paper presents a method of transmission loss to the bilateral transaction trade and nodes.Shapley value allocation regard thd transmission loss allocation as the cooperative game theory problem,no discrimination to each transaction,the method can solve the transactions of the influence and the trading order problem that the power flow tracing method who can not. This paper combines Shapley value allocation method and power flow tracing method and put it into use of the transmission loss allocation under the hybrid transaction model,then lists the allocation model.Example the IEEE14node of the simulation system.Through the simulation example analysis is put forward in this paper compares the two kinds of transmission loss allocation method of characteristics,validation of these two kinds of the correctness and rationality of the mothod.Finally this paper summarize the achievements and deficiency of research.
