Research on optimization of integrated energy system operation under shared energy storage mode

With the increasingly severe environmental pollution problem, the Integrated Energy System (IES) with the power system as the core can promote the consumption of renewable energy. Among them, energy storage will become an important resource in the future energy system. However, due to the cost constraints of energy storage equipment investment, large-scale deployment of energy storage is difficult. Therefore, this article is based on the “sharing concept” to study the optimization technology of regional integrated energy system operation that takes into account shared energy storage. Firstly, an IES operation optimization model considering shared energy storage mode was constructed; Secondly, we constructed a multi-regional comprehensive energy system cooperation game model under the shared energy storage model and formulated benefit allocation strategies based on the subject value label; Finally, an example is used to analyze and evaluate the economic effects of the integrated energy system under different operation modes, to verify the effectiveness and progressiveness of the model.
