Abstract
In the electricity market environment, thermal power units have changed from the executors of power production under the monopoly mechanism to the decision-makers of production and operation under the competitive environment. The merits and demerits of bidding schemes for thermal power units are directly related to self-interest of themselves. The bidding decisions of power plants are not only affected by economic factors, but also by technical factors peculiar to the power system and the electric generator. In recent years, research on bidding strategies of thermal power units based on the power market environment has been paid more and more attention in the field of electric market. This paper first introduces the basic peak regulation and frequency modulation technical characteristics of thermal power units and cost calculation. Then, from the angle of quotation, paper analyzes characteristics of quotation mechanism of units in Fujian Electric Power day-ahead, real-time and peak regulation auxiliary service market. Furthermore, the research status of bidding strategies of thermal power units participating in electricity market at home and abroad in cost analysis, market clearing price prediction, game theory and so on are summarized. Finally, the bidding strategy for units in Fujian Spot Market is put forward.
Highlights
In August 2019, National Development and Reform Commission (NDRC) and State Energy Administration jointly issued “Opinions on deepening the construction pilot work of power spot market” [1], signifying that construction of spot market for electric power in China is entering the stage of further promotion
Based on analysis of bidding mechanism of Fujian electric power market for day-ahead, real-time balance and peak regulation (PR) ancillary services, this paper summarizes the research status of bidding strategies of thermal power units participating in electricity market at home and abroad, and puts forward bidding strategies of units suitable for Fujian spot market
The first part is the introduction; the second part introduces the PR and frequency modulation (FM) characteristics of thermal power units and the calculation method of unit cost; the bidding mechanism of thermal power units in Fujian electric power day-ahead market, real-time balance market and PR ancillary service market is analyzed in the third part; the fourth part summarizes six bidding strategies containing cost analysis, market clearing price prediction and game theory, and put forward unit bidding methods suitable for Fujian spot market; the fifth part is conclusion
