Research on Flexible Trading Mechanism Catering to Requirements of Multiple Entities Under "Generation-Grid-Load- Storage" Interaction

Under the interactive mode of "Generation-Grid-Load-Storage", different types of power resources have been integrated, breaking through the barriers in power production and consumption circulation. As a result, there have been changes in the transaction object, transaction variety, organization mode and clearing method of electricity market transactions. The interaction between “Generation-Grid-Load-Storage” requires the participation of multiple energy resources and entities on the same platform, thereby presenting great challenges to the existing trading mechanism in terms of physical and economic characteristics as well as transactional requirements. Meanwhile, the traditional time-sharing settlement model struggles to sufficiently address the demands of all parties involved. The transaction varieties and declaration methods lack flexibility, hindering the full utilization of their flexible and interactive characteristics. Therefore, it is urgent to accquire a more diversified and flexible market-oriented competition mechanism. In this paper, starting from the concept of "Generation-Grid-Load- Storage" interaction mode, we examine the key factors of its development, analyze the characteristics of power resources under this interactive mode, and summarize the trading characteristics of multiple entities. Based on this, the trading mechanism is designed, providing a flexible trading mechanism to cater to the needs of multiple agents, and a market clearing model is presented. Finally, the effectiveness of the proposed market mechanism is verified through an example, which provides reference for the development of the "Generation-Grid-Load-Storage" mode.
