Research On The Theory And Method Of Power Generation Companies Bidding Strategy In Medium And Long-term Trading

The construction of the power market is the key of the new round of power system reform in China.At present,medium and long-term trading practices have been carried out in the power market for many times,the medium and long-term trading bidding strategy for power products have become the key research topic for generating companies(GENCOs).In this paper,the establishment of medium and long-term trading bidding strategies for GENCOs under the new round of power system reform is regarded as the core of the research,domestic and international power market reform experience and GENCOs bidding decision-making methods are used as the research basis,game theory,and cost analysis model are considered as theoretical supports,the medium and long-term trading decision-making model of GENCOs is constructed combined with the actual trading situation in China's power market.First of all,the basic elements and structure of the power market are analyzed,the medium and long-term trading rules and characteristics of China's GENCOs are summarized.Secondly,the medium and long-term trading decision-making information system of GENCOs is established,the trading environment was evaluated from the internal environment and the external environment system,and the quantification of market trading risks are realized relying on the fuzzy comprehensive evaluation method.Thirdly,the composition and division of medium and long-term trading costs of GENCOs are analyzed,and methods of cost accounting and forecasting are formulated,on this basis,the profitability analysis system of GENCOs is constructed through the CVP model,the power market bidding model of GENCOs is designed,the idea that cost optimization management is the core link to achieve profitability goal is proposed,and the cost optimization model is formulated based on the break-even point theory.Then,the GENCOs trading planning tool is designed to guide enterprises to make scientific predictions from the perspective of electric quantity and price,and the GENCOs bidding decision-making model of the bilateral negotiation trading as well as the centralized bidding are constructed.Finally,the above models are applied to the case analysis,the decision-making ideas of GENCOs in the three stages of operation target establishment,trading period selection and bidding strategy analysis are described in detail,and the feasibility of this research is proved.
