Abstract

Aiming at the potential large number of controllable loads on the demand side of the community integrated energy system, an optimal dispatch model of the community integrated energy system with energy storage considering the demand side controllable load is proposed. Firstly, the framework of the integrated energy system is analyzed and a mathematical model including modules of energy production, conversion, and storage is established. Secondly, three types of load response models are established according to the response types of demand‑side electric and thermal controllable loads. Finally, with the goal of minimizing the comprehensive operating cost of the community integrated energy system in a dispatch cycle, an optimal dispatch model of the community integrated energy system considering the controllable load is constructed. The simulation results of calculation examples show that the participation of controllable loads and energy storage equipment has a positive impact on improving system economy and can effectively reduce the peak‑to‑valley difference of system load, and therefore verify the rationality of the model proposed in the paper.
