This paper presents an energy management system to effectively mitigate grid power profile fluctuations. The system assumes that neither renewable generation nor the load demand is controllable. This energy management system consists of a low complexity Fuzzy Logic Controller embedded with 25 rules in it. The approach is, monitoring rate of change in energy and State of Charge (SOC) of battery thus controlling the power delivered/absorbed by the grid.
