Abstract: Micro-grid supplied by Renewable Energy Sources is characterized by randomness and intermittency due to varying weather conditions. Moreover, increasing demand for off-Grid electricity lead to uneven expansion of Micro-grid structures which may attract additional cost due to complex communication requirements in centralized Systems. In view of the above problems, decentralized control technique is employed in this work to effectively improve energy supplied to an inverter-Based Micro grid by Solar PV and Battery. Droop-based PWM control technique is applied to low Voltage Micro grid at a reference location for effective Energy Management Improvement. Simulations of various operating modes and weather conditions are done in MATLAB/Simulink to validate energy management improvement system. Results obtained showed that active and reactive power is shared between Inverter-connected Energy sources according to their Voltage ratings in Islanded Mode. Coordination technique of energy Management Improvement System supports true Plug and Play Functionalities as DGs can be added to the network with varying voltage Magnitude and location without pre-configuration.
