MPPT based solar and wind energy conversion using power electronic system

Abstract

Solar PV energy conversion system and wind energy conversion system are the alternate sources of energy to the conventional sources such as coal and fossil fuels By operating the converters maximum power can be received from the solar and wind energy conversion system Many Maximum Power Point Tracking MPPT controlling techniques are available for solar and wind energy conversion system This research work proposes two MPPT controlling techniques namely hybrid MPPT and FLC based MPPT for solar PV energy conversion system and modified P and O MPPT controlling technique for wind energy conversion system MATLAB is used to implement the three proposed MPPT techniques The first proposed hybrid method combines the features of incremental conductance and hill climbing methods The incremental conductance method calculate the perturbation direction for operating the PV modules The hill climbing method is simple and less parameters are involved In incremental conductance method Maximum Power Point MPP is reached when dIdV is equal to the incremental conductance In hill climbing method the MPP is reached based on the comparison of power in the present and previous instances In the proposed hybrid MPPT controlling technique both incremental conductance and change of power are considered to reach the MPP This hybrid technique produces maximum output power form solar PV for the different temperature and irradiation levels Hence the proposed hybrid method proceeds in the right direction and quickly reach the MPP newline newline
