A Comparative Analysis between Perturb & Observe and Incremental Conductance techniques for MPPT in PV System

The paper offers a brief overview of the Perturb and Observe (P&O) MPPT and Incremental Conductance (INC) MPPT methods for maximizing the power output of a PV system connected to a rated resistive load. A PV panel can provide maximum power at a fixed operating point only, which is defined at a fixed voltage and current, called as maximum power point (MPP). So, a simulation is carried out to observe I- V & P-V characteristics of PV panel under varying irradiation and temperature conditions to test the genuineness of the MPPT techniques. Additionally, it compares these MPPT techniques based on control strategies, complexity, price, type of circuitry, number of control variables, and performance by utilizing data from simulations performed using the MATLAB Simulink R2022a software.
