MPPT Algorithm for Small Wind Systems based on Speed Control Strategy
Abstract
This paper presents experimental results of an autonomous low-power wind energy conversion system (WECS), based on a permanent-magnet synchronous generator (PMSG) connected directly to the wind turbine. The purpose of this paper is to present an improving method for MPPT (Maximum Power Point Tracking) algorithm based shaft rotational speed optimal control. The proposed method concern the variable delay compensation between measured wind speed from anemometer and wind shaft rotational speed proportional signal. Experimental results aiming to prove the efficiency of the proposed method are presented.
