APPLICATION OF COVID-19 MPPT ALGORITHM TO SOLAR ENERGY CONVERSION SYSTEM
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 paper proposes two MPPT controlling techniques namely Covid-19 MPPT and FLC based MPPT for solar PV energy conversion system. MATLAB is used to implement the two proposed MPPT techniques. The first proposed Covid-19 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 dI/dV 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 Covid-19 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 Covid-19 method proceeds in the right direction and quickly reaches the MPP.
