Research on ancillary service transaction pricing mechanism considering the characteristics of multiple market entities

In order to fully adapt to the addition of new flexible regulation resources, maintain the safe and stable operation of the power system and ensure the quality of power, an auxiliary service transaction pricing mechanism considering the characteristics of multiple market players is proposed for the participation of multiple market players in the auxiliary service market. After a comprehensive analysis of the load characteristics of each entity and the trading mode of the same stage competition and the same quality and price presented in the trading market, a pricing mechanism based on the marginal cost of nodes and the principle of maximizing the benefits of all parties is designed to realize the fairness and efficiency of the transaction. Finally, the simulation results show that the pricing mechanism can not only satisfy the interests of multiple parties, but also improve the market efficiency, which provides theoretical support and practical guidance for the sustainable development of the auxiliary service market.
