Design of the Maximum Power Point Tracking PV System based on P&O algorithm

Abstract

The photovoltaic (PV) power system is one of the renewable energy power sources developing in Indonesia, while the utilization of fossil energy as the primary energy source for power generation decreases significantly. The maximum power point tracking (MPPT) controller can improve the PV power system efficiency. This study presents an experimental design of the Perturb and Observe (P&O) algorithm in the MPPT PV system comprised of a 90-Wp photovoltaic connected to a boost converter and resistive load. The components of the boost converter are determined based on the PV characteristic. The MPPT PV power system is implemented in Simulink MATLAB. The performance of the perturb and observe algorithm is compared to the PV system without an MPPT controller. The results show that perturb and observation algorithm can track the output power at the optimum power
