Abstract
En 中文
This paper presents the design of a new flocking-based distributed controller for an AC microgrid to improve the dynamic performance by regulating the voltage and frequency of each participating distributed generation (DG) unit at the nominal values while meeting the desired power-sharing. In the proposed flocking control design, one DG is considered the leader agent, with the remaining ones as followers. Simulations of the proposed controller were pursued to verify its efficacy in handling sudden load changes, time delay, and plug-and-play conditions. The proposed controller is then implemented in real-time on prototype hardware using the Opal-RT to implement the controller. A comparative analysis is pursued on the performance of the proposed flocking controller with distributed controllers (Li and Chen 2022; Keshavarz et al., 2021; Tong et al., 2023). The comparison results envisage that the proposed controller exhibits improved power balance, plug-and-play performance, reference tracking, and fewer transients.
