In the present day scenario, power demand has been posing a great challenge due to ever increasing power demand as a result of population growth, new industry development, etc.; rapidly depleting fossil fuels makes us to switch to the other power source as the fossil fuels impacts environment in many aspects. Hence the need of the hour is to concentrate on alternate energy source which must be environment friendly as well. An analysis of photovoltaic cell operation under various weather conditions was performed and based on that, MPPT controller was developed exclusively using a FLC (Fuzzy logic controller). The primary goal of this research work is to propose intelligent control-based energy management system for microgrid integration of photovoltaic power scheme with the energy storage device. The intelligent controller operates the bidirectional converter for battery charging and discharging depended on power demand. The proposed structure has been modeled in the MATLAB environment and the system performance was analyzed accordingly. Finally, the simulation results were evaluated and compared with IEEE 1547 standard for evaluating the efficiency of the anticipated system.
