Abstract

To solve the cooperative game problem of multi-energy sharing among cross regional integrated energy systems in uncertain source load environments, firstly, considering the multi-energy collaboration characteristics between cross regional integrated energy systems, taking the wide area integrated energy system interconnected by multiple cross regional integrated energy systems as the research object, a multi-energy sharing cooperative operation model for wide area integrated energy systems is constructed. Secondly, in order to solve the cooperative game and fair distribution of benefits between resource endowment integrated energy systems, a Nash negotiation model for wide area integrated energy system electric and thermal sharing based on asymmetric bargaining is proposed on the basis of the established integrated energy system model. Then, in order to protect the data privacy of cooperative entities and reduce the impact of source load uncertainty and improve the reliability of Nash negotiations in wide area integrated energy systems, a two-stage robust Nash optimization method of day-ahead real-time is proposed, and the alternating direction multiplier method and column and constraint generation algorithm are used for solving. Finally, through case analysis, it is verified that the proposed model and method can effectively improve the adaptability of strategies, fairness of benefit distribution, and low-carbon economy of the system in uncertain environments.
