Abstract: With the rapid development of energy storage technology, it plays an increasingly important role in the integrated energy system of industrial enterprises. For industrial enterprise users, this study builds an integrated energy system that considers the participation of energy storage operators. Based on the basic standpoint of cost sharing, benefit sharing, risk sharing and win-win cooperation, the optimal operation strategy of the energy system and the reasonable distribution of synergistic benefits are discussed. Firstly, considering the power load demand response, a mathematical model of integrated energy system operation optimization with coupled energy storage is established. Secondly, a three-level evaluation index system covering direct economic benefit and indirect social benefit is constructed. On this basis, we adopt the model of monetized value to evaluate the synergistic benefit quantitatively, and realize the fair benefit distribution among multi-interest subjects based on the cost-benefit method. The results of the case show that the mathematical optimization model and benefit distribution mechanism proposed in this study are reasonable and effective.
