Transmission Losses Allocation Using The Owen Value Of Cooperative Games

Nowadays electric utilities and national electric regulated/management organizations all around the world pay more and more attention to the transmission open access (TOA) in the electricity market. Under the electric market environment, TOA face a series of technological difficult problems, and transmission losses allocation is one of them. It is a key problem that how to allocate the transmission loss fairly, rationally and accurately among the electric market participants, and an important matter of transmission pricing and a basic requirement of fair play in the electricity market.Transmission losses cost is up to the load flow in the electric power system. It is a complicated problem to how to fairly allocate the cost according to the influence of individual transactions to the power flow. Various calculation and allocation methods for transmission losses will make a great deal of difference of allocation results among the market participants, and have a great impact on economical operation of energy supply system. Therefore, it becomes a problem that generally pays close attention to how to accurately calculate and fairly allocate the transmission losses.This thesis firstly analyses several existing methods for transmission losses allocation, then points out their characteristics and discusses in detail some issues that should be paid attention to and then presents some principles for transmission losses allocation. Directing against these principles and main issues, and proceeding from game theory in mathematics, the thesis expands the rationality conditions of cooperative game theory and presents a new approach to equitably allocate the transmission losses among the power market participants using the nested cooperative game structure in the game theory.This thesis comes to launch analyzing and studying rounding the most basic electricity market principle-the "fair principle" from the beginning to end and it is unanimous with the essence of the transmission losses allocation problem.Some numerical test simulations are used to compare the method presented by this thesis with those traditional allocation method introduced in this literature and results of the comparisons shows that the new allocation methods is equitable and effective.At last, the thesis summarizes and prospects the whole work.
