A Multi-entity Operation Strategy for Integrated Landscape Energy Systems Considering Cooperative Games from a Synergy Perspective

Abstract

In this study, we propose a multi-body operation strategy for a scenic integrated energy system that takes cooperative game into account in order to promote the "double carbon" plan and the more efficient utilization of clean energy. Initially, the respective operation models for wind farms, photovoltaic systems, and integrated energy systems are established. A cooperative operation model of the integrated landscape energy system is established and translated into subproblems of coalition benefit maximization and power trading payment using Nash's negotiation theory. This paper proposes a solution algorithm for the coalition benefit maximization and power transaction payment problems using the alternating direction multiplier method, as each entity can only cooperate in their respective domains using local information. The results of the case study indicate that the strategy effectively resolves the problem of electric energy trading and price between energy entities in the integrated scenic system, thereby increasing the benefits of cooperative operation for each entity. Reducing the feed-in tariff of wind and light can also improve the cooperation between wind, light, and integrated energy systems.
