Maximum Power Point Tracking and MPPT efficiency for wind and solar energy conversion standalone system

This paper focuses on simulation analysis of Maximum Power Point Tracking Algorithm (MPPT) for small scale Wind Energy Conversion System (WECS) and Solar Photovoltaic (SP) module for power generation. The existing MPPT algorithms for WECS use DC current as the perturbing variable whereas change in wind speed is detected with the help of change in dc voltage. While in case of Solar (PV) maximum power is tracked by DC power taking voltage as a perturbing variable. The algorithms have implemented in PSIM ® 9.1.4 software. The performance of the algorithm is found to be satisfactory for power generation application as the MPPT efficiency obtained is of the order of 80% and 98.32% for wind and solar respectively.
