An improved MPPT algorithm for wind energy conversion system

Abstract EN

This paper presents a comparison between MPPT algorithms used for extracting maximum power from the wind energy conversion system (WECS).

These MPPT controllers can be classified in to three main control algorithm, namely optimal torque control (OTC), power signal feedback (PSF) and hill-climb search (HCS).

Most control schemes use the HCS technique, because it’s simple and easy to implement, but it’s less efficient and present wrong directionality under rapid variation in wind speed.

To solve these problems, Hybrid HCS method (HHCS) is proposed; it combines OTC and HCS control for obtained a step sizes of the hill climb technique.

A comparison has been made between the performances of the different MPPT algorithms on the basis of speed responses and ability to achieve the maximum energy.

The performance of the proposed control is validated through simulation results.
