Abstract:
      The selection of energy storage system is the primary link of energy storage participation in the planning for power grid peaking shaving and frequency regulation, and it is of significance for the promotion and application of energy storage. In this paper, a method based on analytic hierarchy process (AHP) and criteria importance though intercrieria cor-relation (CRITIC) is proposed to select an energy storage system for power grid peaking shaving and frequency regulation. By analyzing the operating conditions of the energy storage system in the peaking shaving and frequency regulation scenario, a two-layer decision index system for energy storage system selection is constructed. Based on expert experiences and technical requirements, the AHP method is used to determine the index weights in the first layer. Considering the variability within indexes and the conflict between each of them, the CRITIC method is used to determine the index weights in the second layer. The comprehensive score for various types of energy storage system is given by combining the index weights in two layers. The proposed method provides a theoretical basis for the planning of power grid peaking shaving and frequency regulation at an energy storage power station, and has certain engineering application value.
