摘要：
With the electricity market opening gradually in China, the end-users are transiting to the prosumers and the complementarity of multiple energy increases continuously, thus cloud energy storage business model may become a new form of user-side energy storage in the future. In this paper, the business model of cloud energy storage is applied to the joint optimization of electric and thermal energy storage in the integrated energy system. Firstly, with the analysis of the characteristics of cloud energy storage, the energy hub structure with cloud energy storage is established to illustrate the transformation relationship between the input and output. Then, the optimal optimization method of electric and thermal cloud energy storage in the regional integrated energy system is proposed, based on a double-layer programming model. In the inner layer of the model, the electric and thermal energy storage requirements of all users are optimized from the perspective of the users. In the outer layer, all users' energy storage requirements from the inner layer analysis are integrated, and the configuration of electric and thermal cloud energy storage are comprehensively optimized from the perspective of cloud energy storage providers. Finally, this model is applied to three different scenarios and solved by CPLEX. The results of case studies show that the cloud energy storage mode can utilize energy resources more efficiently and reduce costs. Also, the user, the cloud energy storage providers, the power grid and the heat network can achieve mutual benefits and the win-win situation. © 2020, Power System Technology Press.
