Considering the development of power market in china, and based on the research on power market aboard, this passage analysis problems of hydro-thermal coordinate system from two sides of the market, pointing out how hydropower plant participates in market competition. Then some adjustments are made to the model of hydro-thermal coordinate system in competitive power market. Considering the possibility of discarding water by the misplay of hydropower companies and the acute change of the weather, the model of coordination of generation-right trade and discarding bid is raised. Finally, it makes a proof of competition between hydro and thermal systems by releasing Day-Ahead generation schedule programme under the trading model. |
