The Study Of Grid Transmission Loss Cost Allocation And Settlement Methods Under Power Market Environment

Under power market environment,the transmission loss allocation problem is no longer a simple average share way draw the loss cost back and forth,but in different market mode,how to combine the market model and geographical characteristics of local conditions to loss allocation to each user.The basic principle of loss allocation is fair and reasonable,the purpose of this paper is to analysis how the different market pattern net loss cost a fair share to all users in the market.In this paper,the main research contents include the following: 1.study the power market at home and abroad and the net loss allocation method and the method of payment,and mainly compare and analysis on the applicability of the market model.On the calculation method of model analyzes the advantages and disadvantages of various algorithms,mainly study the marginal loss coefficient method is widely used at home and abroad,put forward the improvement method based on the balance of node selection,and make contrast before the example analysis and improvement;2.from the object of loss allocation,the method of payment,network loss coefficient to distinguish the quarter from several aspects,comprehensively research network loss and settlement method,and puts forward some original points area and quarterly net loss coefficient calculation,the method of analysis of the bilateral trade and collective trading through bidding mode applicable network loss settlement method;3.in the context of electricity market in our country,and market pattern in Inner Mongolia,Yunnan,Guangzhou is discussed in Yunnan electric power market mode as the background,large user network loss trading and settlement method is put forward,by an example and analyses the influence of network loss included in the price competition in the market.Transmission loss allocation is to guarantee the fairness of cost-sharing between the user and clear their respective need to take responsibility,to establish a complete electricity market operation mechanism provides a theoretical reference.
