Methods Of Loss Allocation In Electricity Markets

This paper is divided into five chapters. In these chapters, loss allocation, which is anxious to be solved in business running of power network, are respectively about state-of-the-art of electricity markets, market structure and transaction mode, optimal power flow in electricity markets, loss allocation in transmission services, allocation method based on cooperative game theory.In chapter 1, the state-of-the-art of electricity markets, market structure and transaction mode are studied, including state-of-the-art of some typical overseas electricity markets and our state's electricity markets, the market structure and transaction mode of our state's electricity markets. Loss calculation, the significance and technology difficulty of the loss allocation problem, the loss allocation methods of both here and abroad are introduced.In chapter 2, the issue of loss allocation in transmission services is introduced. The demands of loss allocation in different transaction modes are analysed. The object of loss allocation is brought forward. The existing loss allocation methods are also summarized.In chapter 3, integrating with the conception of cooperative game theory, cost allocation method of economics is applied to the issue of loss allocation. A method which is based on novel nucleolus theory for power losses allocation under bilateral-transactions (or multilateral-transactions) model and the existing loss allocation method, which is based on Shapley-value, are put forward. These methods can factually reflect transactions bearing responsibility for system losses and are logical. Some simulation examples test these methods, which are put forward in this paper. The result testifies that these methods are correct and logical.In chapter 4, optimal power flow in electricity markets and routine flow are analysed. Simulation examples test optimal power flow. And which flow program should be used to calculate loss is analysed. The analysis indicates that market participants should be more willing to accept the allocation result which is calculated by the optimal power flow program.In chapter 5, the main work and original researches in the paper are summarized.
