Implementation of simple moving voltage average technique with direct control incremental conductance method to optimize the efficiency of DC microgrid

Abstract

Simple moving voltage average (SMVA) technique to fetch the maximum power from solar photovoltaic under non-uniform solar irradiation conditions and stable output voltage for DC-DC boost converter is introduced in this paper. In order to ensure the bus voltage stability of DC microgrid, the power flow within the grid must be balanced at all times. So far, different maximum power point tracking (MPPT) techniques are used to optimize the solar photovoltaic system efficiency. Incremental conductance (INC) algorithm is one of the widely used method as compare to others, due to its simplicity and accurate response to track MPP under steady and dynamic states. To validate the performance of proposed techniques MATLAB/SIMULINK simulations are presented in this paper, simulation results shows that proposed technique works more accurately and faster during dynamic and steady state conditions and improve the overall system efficiency.
