Research on Energy Management of Integrated Energy Systems Considering Multi-agent

With the rapid development of China's economy, energy shortage and environmental pollution gradually become serious. The integrated energy system provides a way of thinking for the transformation of China's energy structure. And with the development of the electricity market, different stakeholders will emerge in the integrated energy system. In view of the multi-energy coupling characteristics of the integrated energy system and considering the coexistence of multiple stakeholders, this paper first classifies the system into different entities based on the operating characteristics of each device in the system and the” Source-Grid-Load-Storage” as a clue. Then, according to the profit mode of each subject, the corresponding benefit model is established, and two energy management strategies, centralized and coordinated, are proposed to realize the goal of maximizing the overall income of the integrated energy system or equalizing the income of each subject through the dispatching of the energy management center. While ensuring the safe, stable and efficient operation of the integrated energy system, the interests of all subjects are protected.
