Study on Economic Operation of Multi-Type Load Demand Response in Park with Shared Energy Storage

Aiming at the dispatchable resources of the power system in the park, a demand response model with flexible loads is constructed, taking into account the characteristics of user-side flexible loads that can be shifted, transferred, and curtailed, and a two-layer optimization model of the park's integrated energy system is established with the goal of maximizing the operating revenue of the energy storage power plant and minimizing the total operating cost of the park, and the proposed strategy is validated through simulation based on the KKT condition, Big-M method, and the use of the Yalmip toolbox and the Cplex Based on the KKT condition and Big-M method, the Yalmip toolbox and Cplex solver are utilized to solve the capacity allocation of the shared energy storage plant and the economic operation of the park users, and the feasibility and effectiveness of the proposed strategy are verified through simulation.
