| Summary: | Decentralized control is an effective approach to use in direct-current (DC) microgrids (MG) system for various reasons, including ease of design and execution. A well-designed secondary controller will be implemented with the traditional primary controller for an islanded MG systems with the goal of restoring DC bus voltage and allowing current sharing. The local decentralized controller has significantly lowered the communication and implementation costs compared to existing centralised and distributed control methods by only require DC bus voltage data.
Additionally, the decentralized controller also implements with event-triggered condition to cut down on the signal communication costs. It shows that the voltage restored the rated voltage with minimum error.
The purpose of this FYP is to understand and simulate the secondary controller with different control parameters. MATLAB Simulink will be used to simulate the islanded DC microgrid system and prove voltage restoration and current sharing capability. |
