With the advancement of integrated energy systems, the interconnection technology for multi-park integrated energy systems has emerged as a prominent area of research. Drawing upon cooperative game theory, a cooperative framework for integrating industrial park and residential area energy systems is proposed, while enhancing the low-carbonization model of cogeneration units. Furthermore, considering electric vehicle batteries’potential as mobile energy storage devices, charging stations are incorporated as third-party participants in power storage and grid peak-valley regulation. Subsequently, Nash bargaining theory is employed to address the issue of benefit distribution within cooperation by formulating it as both a subproblem of maximizing benefits and distributing them equitably. To ensure information privacy among different entities involved, an iterative solution using alternate multiplier method is adopted. Finally, exemplary results demonstrate that compared to independent operation modes, overall costs can be reduc with respective cost reductions for residential operators, industrial park operators, and charging station operators, thus validating the effectiveness of the proposed strategy.
