Real-Time Simulation of Wind Energy Conversion System with LCL Filter and Resonant Control System with Active Damping through Hardware in the Loop Technique

Abstract

In this paper, a real time simulation of a wind energy conversion system with LCL filter and resonant control system with active damping is achieved by using “Hardware-in-the-loop” methodology. This technique allows to experimentally test different control strategies without requiring a physical wind turbine. In this work, the modelling of the wind turbine, wind profile, the design of controls as: pitch control and maximum power point tracking algorithm is discussed. Furthermore, a current control
based on resonant controllers and active damping compensation is implemented to damp the LCL filter resonance frequency and to supply high power quality to the grid. The Hardware in the
Loop technique is implemented on Matlab/Simulink platform of Triphase PM5F60R embedded system. This unit is a power converter connected to the grid in back-to-back configuration.
