Maximum Power Point Tracking Using Perturb and Observe Technique

Abstract

The research on Maximum Power Point Tracking (MPPT) using Perturb and Observe (P&O) is conducted to observe the behavior of the I-V curve output from the PV cell. The MPPT will track the maximum power point using the P&O algorithm. The P&O is widely known for its simple implementation on the PV system. The P&O method will enhance the efficiency of the PV cell. The P&O algorithm is designed using MATLAB coding (mfile). The mfile can be inserted in the circuit design in the Simulink. Simulink is used to design the PV circuit. The PV connected to P&O algorithm is tested under multiple condition. The outcome of this analysis is the maximum power point (PMP), voltage at maximum power point (VMPP) and current at maximum power point (IMPP). From there, the characteristics of the PV module can be study. The P&O output is than compared with the datasheet where for this research uses Soltech 1STH-215-P. This is to obtain the efficiency of P&O algorithm.
