A Novel Grid Integrated Perturb and Observe Maximum Power Point Tracking Controlled Photovoltaic Power Plant for Power Enhancement

Abstract

Solar Photovoltaic power generation shows considerable growth in the past decades. In the grid integrated PV system require MPPT controller to improve the efficiency of the power harvested from the plant due to nonlinearity nature of PV module. Among many MPPT Technique P&O has adaptive tracking, reduced oscillation around MPP. In this paper the Perturbation and Observation based MPPT algorithm with adaptive duty ratio generation is used. In this Paper in addition to PV power generation it is used for the power correction of the utility grid by injecting the power to balance the system during unbalanced load condition. Simulation of the proposed concept is run in the MATLAB 2018/Simulink environment.

A Novel Comparative Analysis of Solar P&O, ANN-based MPPT Controller under Different Irradiance Condition

“…The easiest way to track the MPP in a panel is with the P&O algorithm. In this method, the power generated at the present moment P(k) is compared to the power generated at the previous moment P(K-1) based on the oscillating duty cycle to reach the MPP point [12].…”
