In power industry due to fast industrialization the generation system has upswing towards strongly procuring energy from various non-conventional energy sources (RES). Persistent work is carried out in order to use additional energy obtained from the renewable sources and limiting the dependence on the conventional energy sources. The amalgamation of various Hybrid Renewable Energy Sources (HRES) i.e. Solar, Wind and Fuel cell including load forms a Micro grid, the realistic management of energy from these renewable sources to accommodate the demand at the consumer end with proper efficiency is necessary. This paper proposes a hybrid system comprising of three energy sources PV, Wind and Fuel Cell and is connected to the grid by using power electronic converters using MATLAB/SIMULINK. A control circuit is designed by using PI controller and fuzzy logic based controller for providing gate signals to the inverter. The voltage profile when connected to a load by using various controllers is studied. A comparison study and behavior of source voltage, source current, load voltage and load current is studied by using PI controller and fuzzy logic controller.

“…Thus, for example, in [6], dc bus voltage levels are used to indicate the system state, so that energy storage can be regulated through the dc bus, focusing on system dynamic techniques as opposed to optimization approaches for optimal system operation. A rule-based EMS is proposed in [7] for dc microgrid operation, as opposed to applying optimization-based techniques for energy management. To the best of the authors' knowledge, there are not many papers on dc microgrid EMS based on optimization techniques similar to those that have been proposed for ac microgrids.…”

DC microgrids require sources that maintain dc microgrid voltages, with Battery Energy Storage Systems (BESSs) being a good option for this task, given their multiple control alternatives. However, BESS cycling is an issue, and thus, this paper proposes an Energy Management System (EMS) for dc microgrids that considers battery degradation. Therefore, an EMS model is proposed and discussed, demonstrating its application for a practical dc microgrid of a building in Xiamen University. The simulation results show that the proposed EMS, which accounts for BES degradation costs, is an effective tool that avoids frequent battery charging and discharging, while maintaining the required dc bus voltage.
