摘要：
To solve the problem of traditional droop control in a DC microgrid cannot meet both current equalization and voltage regulation requirements in load distribution due to the presence of line impedance. This work proposes a fuzzy logic-based improved droop control scheme and designs two fuzzy controllers for the current compensation and bus voltage compensation, respectively. To improve current equalization accuracy and DC bus voltage stability, voltage compensator and current compensator based on fuzzy logic algorithm are designed. Finally, a simulation platform of the DC microgrid with three phase-shifted full-bridge DC/DC converters as the main circuit topology is built in MATLAB/Simulink to verify the feasibility and effectiveness of the proposed control scheme.
