A novel approach of project is to model and control of a battery management system used in microgrid.The system composed of photovoltaic array and battery. The photovoltaic array normally uses a maximum power pointtracking (MPPT) technique to continuously deliver the highest power to the load, when there are irradiation andtemperature. The disadvantage of photovoltaic energy is that photovoltaic output power depends upon weathercondition and cell temperature making it an uncontrollable source. To make the system controllable, the battery isconsidered. This battery compensate the load variations when solar power is damping in nature.System has two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode,applied to hybrid system. When load is light, the UPC mode is selected. In UPC mode variation in load demands arecompensated by the main grid because the hybrid source output is regulated to reference power. In FFC mode feederflow is regulated to a constant power, the extra load demand is picked up by hybrid sources and hence feeder referencepower must be known. The system can maximize the generated power when load is heavy and minimizes the loadshedding area.The proposed operating strategies with flexible operation mode change always operates the photovoltaic array atmaximum output power and battery in its high efficiency performance band, thus improving the performance of systemoperation, enhance system stability, decreasing the number of operating mode changes in the MATLAB Simulinkenvironment.
