In this study, a micro-grid controller, integrating the output from multiple types of renewable energy conversion systems, namely, wind and solar along with diesel generator as well as battery storage has been developed with source and load control features using field programmable gate arrays (FPGAs). The load controller facilitates load management (switching ON/OFF non-critical loads) based on the generation availability and energy storage capacity. The source controller facilitates source management based on the load requirement and battery status. The various parameters of these different power generation sources and loads are displayed on visual
screen using FPGA for online condition monitoring of the micro-grid. It also includes the communication between source and load controllers using Ethernet for exchange of monitored data for a suitable control action.
