Optimal Operation Strategy of Park-level Integrated Energy Systems Considering Carbon Trading

As the energy market reform deepens, the park-level integrated energy system (PIES) can provide users with diversified energy and play an important role in energy conservation and emissions reduction. This paper considers the impact of uncertainty in integrated energy flows and renewable energy on energy trading within the PIES, taking into account the goals of low-carbon economic. At the same time, a cooperative game mechanism for the interconnected PIES considering carbon trading is designed based on Nash bargaining theory, aimed at encouraging active energy trading and fair benefit sharing among various PIESs. To protect the confidentiality of each PIES, the ADMM method is used. Finally, through the analysis of three interconnected PIESs, the economic and environmental benefits of the proposed method are validated.
