The Operation And Researche Of AGC Within Power Market

The establishment of generation side power market alters the operation mode of current power system, thus leads to a serial of problems confronting traditional AGC. This thesis presents an explication and discussion on the operation of AGC within power market. The origin and significance of power market as well as the fundamental condition domestic power market are introduced, and then the influence of power market on the operation of AGC is discussed.Based upon a comprehensive comparison and evaluation on current bidding mode for AGC market, combined with the practical condition, the mode ahead of energy market is suggested by the author. Meanwhile, the determination of capacity and velocity for AGC adjustment as well as the problems of assessment and settlement are explored.According to the deficiencies and problems of current strategy of choosing AGC units, an improved integer programming is put forward to achieve the choice. The computing case proves it practical and effective. Meantime, with the analysis and comparison of the practical numerical cases and other methods, the practicability and effectiveness is proved.A primary exploration was made to achieve the most profits with the union of energy market and AGC market on the basis of the certain water used . As the result of simplification, there is the main consideration about the conformity under the relation of linear and nonlinear, which is the load and flux of fix head, thus gain the most profits by accord with energy market and AGC market. Meantime, the result is correct and feasible, manifesting by the validation, which is the natural outcome by the numerical case's conclusion of linear relation under the condition of fix head and flux.AGC is of great significance for the stability, security and economy of power system,but AGC for power grid is being challenged within power market. The current researches on AGC within power market are still superficial, this thesis provides an overall introduction and exploration. There is an significant achievement of above 4 aspects with the active examination in this thesis.
