Optimization of Standalone Microgrid Considering Active Damping Technique and Smart Power Management Using Fuzzy Logic Supervisor

Microgrid (MG) is attracting considerable attention as a solution to energy deficiency, especially, in remote areas. A MG is defined as a group of interconnected loads and multiple distributed generators that are usually integrated via voltage source convertors (VSC) and is able to operate in both grid-connected or island-mode. In order to enhance power quality and power energy management reliability, MG needs optimization in terms of control and size reduction of components. To make some contributions, this paper analyzes three aspects: 1) developing a new approach of active damping technique based on mathematical model of VSC without any additional sensors; 2) reducing the size of the output LC filter by shifting the frequency and adjusting the active damping coefficient; and 3) building a strong fuzzy logic supervisor for smart power management. The simulation and experimental results demonstrate excellent performance of the proposed design and control approaches.
