Busbar Voltage Control of DC Microgrid Group Based on Whale Optimization Algorithm and Fuzzy Control

Abstract

Aiming at the problems of system response lag, poor anti-interference ability, and poor recovery ability of fuzzy dual closed-loop control, this paper proposes a fuzzy dual closed-loop control based on a whale optimization algorithm to optimize the control effect by simulating the foam attack mechanism of humpback whales, solving mathematical and structural optimization problems, adjusting quantization factor and scaling factor, and adjusting PI parameters in real-time. Matlab/Simulink is used to create the model. The experimental results show that the system has a quicker reaction, smaller overshoot, greater anti-interference capability, and improved robustness in various situations under the new control strategy.
