Abstract

Firstly, modeling renewable energy generation and energy storage devices based on the supply/storage characteristics of the park, and establishing various equipment operation constraint models. Secondly, taking the lowest cost of the integrated energy system in the park as the upper level planning objective and the operating cost as the lower level scheduling objective, genetic algorithm is used to solve the optimal source/storage capacity planning configuration. Considering the optimization problem of operation in planning, the adoption of flexible load control serves to reduce the disparity between peak and off-peak loads and alleviate the pressure of peak energy consumption. Finally, the superiority of system planning under energy supply reliability is verified through practical examples in urban parks. The proposed method can meet the load demand of the system while ensuring economic efficiency.
