APPLICATION OF KALMAN FILTER IN MAXIMUM POWER POINT TRACKING OF SOLAR PHOTOVOLTAIC CELL

Abstract

his paper proposes implementation of a new MPPT technique using Kalman Filter. The approach uses
Kalman filter algorithm to track maximum power point. Using this approach tracking becomes much faster than using the
generic Perturb & Observe algorithm in case of sudden weather changes. Experimentation was performed under optimal
conditions as well as under cloudy conditions i.e. falling irradiance levels. Using the proposed technique the maximum
power point of a solar PV array is tracked with an efficiency of 97.11%. Moreover, the maximum power point has been
tracked at a much faster rate i.e. 4.5 ms using the proposed algorithm compared to the existing generic Perturb and Observe
approach.
