Resarch On Market Mechanism And Competition Mode Of Hydro-thermal Optimizing Configuring And Application

Hydrodynamic power and thermal power are the dominating power types which will bid in the power market in China. The optimization configuring market mechanism of hydro-thermal power system is one of the core contents of the power market design and fire-new task in our country. As the economic relation(pricing) inside the eletricity industry and between the eletricity industry and the upriver resource industry and downriver consumers hasn't been radically settled, in order to optimization harmonizing and configuring of hydro-thermal power system, the upriver, medial and downriver configuring problems have to be made overall plans and take all factors into consideration. Under the background of the eletricity reformation of China, this paper discuss the theories and methods and their application of market mechanism establishing and harmonizing mode in four tache of water and coal resource optimization configuring, hydro-thermal power system competitiion, power transmission and distribution, selling, in oder to provide theoretic instruction in processing the whole resource system optimization configuring through market mechanism and demand side response, price reflecting the resource worthiness and rarity, creating well competition environment, inducting reasonable enhancive investment and putting the policy of circumstance protection into effect.The subsistent excogitations of the power market mechanism and competition model are popularly designed for the thermal power only and less for the interior or exterior of the hydro-thermal power system harmonious optimization. Based on the economic and power market theories, this paper studies and designs the market mechanism, competition models and concerned measures for the hydro-thermal power system in allusion to the characteristic and the especial problems they have to face in competing in one market, such as the cost difference between hydrodynamic power and thermal power, preferentially utilizing hydrodynamic power and the risk from water fluctuation. In the same time, this paper considers optimization configuring in the uprive and downrive of the power market and the two former core contents as a whole, and establishs the market mechanism system of optimization configuring of the hydro-thermal power system in order to realize harmonious optimization among the power market and its uprive and downrive. The paper adopts the method of combining on theories studying and application analysis, studies the theories of the market mechanism system of optimization configuring of the hydro-thermal power system under the background of the eletricity reformation of China and applies these fruits in the demonstrations through the factual research tasks to insure them practical foreground. So the fruits of this paper can be used as theoretic instruction and decision-making reference for in designing and operating the the market mechanism for the hydro-thermal power system optimization configuring in China.The central fruits of this paper: (1)The whole frame of the the market mechanism designing for optimization configuring of the hydro-thermal power system is put forward,and the linkage mechanisms between the power price and the uprive resource price and the linkage mechanisms between generationg side and selling side are all argumented in the view of resource optimization configuring inside and outside the hydro-thermal power system; (2)The theories system of water and coal resource optimization configuring is brought forward and the congruent mechanism for the near future in China is analysised and argumented; (3)A lot of modes of hydro-thermal power system bidding in the primary market and in the auxiliary market, ladderlike hydrodynamic power competition grouping and harmonizing mechanism and generating might trading are advanced and contrastively analysised; (4)Three competition models of hydro-thermal power system respectively basded on mechanism of optimizating of generator unit output, mechanism of biding of providing function and game theory are constituted; (5)The pricing mechanism for power transmission and distribution being congruent for China nowadays is educed; (6)The demonstration processed for theories, modes and methods which are put forward in the paper. Among these fruits, the central contents of (1), (2) and (4) and partial contents of the other fruits have comparatively innovative contribution.
