This paper presents the integration of photo voltaic inverter and battery based energy storage system in a micro grid network, to achieve efficient energy management using interleaved boost converter with Maximum Power Point Tracking (MPPT) controller. The regulation of battery operations i.e., battery hold, charge and discharge actions depending on the requisite of load are achieved using a bi-directional DC-DC converter. The performance of a simple boost converter and interleaved boost converter with MPPT control has been analyzed and compared with i. Two-level inverter and ii. Three-level NPC inverter for the scenarios like PV source completely catering to the load demand & charging battery, PV source catering only to load demand, Battery storage system catering to load demand and finally PV source & battery storage system both together caters to the load demand. The output Power, Voltage and Current waveforms are analyzed for all the above mentioned scenarios and the results are compared for arriving at better performance. The proposed micro grid energy management system has been modeled and analyzed using MATLAB/Simulink tool.
