Research on Regulation Capacity Mining and Regulation Technology of Park Considering Multi-Form Resources

In recent years, in the case of vigorously building new energy systems in China, the insufficient absorption capacity of regional power grids has become increasingly prominent. In order to alleviate this phenomenon, this paper studies the scheduling capacity estimation and mining methods of large-scale integrated energy parks, and the benefit interaction mechanism between park users and regional distribution networks. Based on the economic dispatching of the park under the framework of time-of-price, an estimation method of the dispatchability of the integrated energy system based on energy path tracking is proposed to obtain the conservative evaluation of the dispatchability of the integrated energy system. Then, a simplified model of the efficiency function of the integrated energy park is established, and an interaction method between the distribution network and the integrated energy park is formed. On this basis, a Stackelberg game model of "distribution network and park" is established. An improved differential evolution algorithm is proposed to optimize and solve the problem, and the equilibrium solution of the distribution network’s electricity price to the park is obtained.
