Distributed Model Predictive Control of Wide-area Multiple Energy Storages Considering the Delay Compensation

To address the impact of communication delay, which occurring the participation of wide-area multiple energy storages in power system frequency regulation, this paper designs a delay compensation distributed model predictive control (DC-DMPC) method. Firstly, according to the frequency response characteristics of the main components in the interconnected power system, the state space model of the frequency response of the connected power system is established. Then, a communication delay compensator is added to distributed model predictive control (DMPC) to compensate for the communication delay. Finally, the simulation of the DCDMPC system is implemented in MATLAB, and the experiment result proves that the proposed method can enhance the system’s robustness and effectively compensate for the communication delay.
