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.
