Abstract: Under the background of energy transition, the energy coordination optimization of multi-park integrated energy system（MPIES） has received special attention. In view of the multi-agent distribution and autonomy characteristics of the multi-park integrated energy system, the centralized scheduling model with model solving difficulties and subject privacy issues will be difficult to sustain. In this paper, a multi-agent economic dispatch architecture and competition and cooperation mechanism are proposed. The MPIES game cooperation optimization dispatch model is constructed using the game cooperation theory, which is solved by the alternating direction method of multipliers（ADMM）, and the algorithm flow is given. The MPIES cooperative scheduling model realizes the energy interaction between PIES and fully taps the energy potential of the parks. It not only effectively improves the utilization rate of new energy and the service life of power storage equipment, but also has good environmental protection. The calculation example takes the multi-park integrated energy system as an example to conduct analysis, and the results verify the effectiveness and accuracy of the proposed method.
