Fuzzy Logic Based Grid Synchronization with Renewable Energy Sources and Energy Storage

Micro-grid is a promising area that might provide a solid solution for more and more stress on the utility supply and transmission line. Generally micro- grid comprise of renewable energy sources such as photovoltaic (PV), wind, fuel cell (FC) stack etc., as micro-grid involves renewable energy sources which have a significantly different dynamic behavior, dissimilar generating capacities and disruptive effects such as voltage dips and fluctuations, frequency variation, and harmonic distortion are handled through centralized monitoring in conjunction with hierarchical control. This paper proposes a GS technique based on controller area network (CAN) communication. CAN is a robust fault tolerant multi host serial communication network capable of providing 1 Mb/s data rate. The proposed scheme is based on CAN communication between the microgrid master controller (MMC), local controllers (LC), load controller and grid synchronization system. The reliability and sustainability of the resulting complex micro-grid synchronization is ensured through the proposed reconfigurable control and power network of the micro-grid, supported by a comprising fuzzy controller areanetwork
