Direct torque control for squirrel cage induction generator based on wind energy conversion system with battery energy storage system

Abstract

This paper presents a new configuration for a wind energy conversion system (WECS) using a squirrel cage induction generator (SCIG) with battery energy storage system (BESS). The proposed configuration utilizes power converters, operates with maximum power point tracking algorithm to maximum wind energy extraction. The SCIG is connected to the power grid through back to back voltage source converters, and the WECS is reinforced by BESS in order to keep the voltage and frequency of the grid constant, during the variation of wind speeds and the power system. The DC-DC converter (buckboost) is connected with the back to back converter to control the battery bank and to maintain DC-link voltage constant. The SCIG is controlled using the direct torque control strategy and, the active and reactive power of grid side converter is controlled by means of simple vector control. The vector control of the SCIG side and power grid side converters were implemented in SimPowerSystems R of Matlab/Simulink R . The simulation results showed the effectiveness of this approach.Index Terms-Battery energy storage system, direct torque control, squirrel cage induction generator, voltage sourced converter, wind energy conversion system.

Comparative Analysis between PI and Linear‐ADRC Control of a Grid Connected Variable Speed Wind Energy Conversion System Based on a Squirrel Cage Induction Generator

“…To ensure the accurate integration of the WEC-System with the utility grid, the regulation of active and reactive powers is needed as well as the synchronization of voltage and frequency. In this context numerous publications are found in literature as, in [3], the authors proposed an indirect vector control of a Squirrel Cage Induction Generator wind turbine where the objective is to control the DC-bus voltage and the reactive power by using the classical Proportional Integrator (PI) controller, authors in [4] used the Sliding Mode Control to drive the WEC-System based on a SCI-Generator, authors in [5] proposed a Fuzzy Logic Control of a variable speed cage machine wind generation system, and, in [6], the authors have used the Backstepping technique, Furthermore, additional types of controllers were also considered for squirrel cage-based WEC-Systems as cited in [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Nevertheless, another controller appeared in the last 10 years and it is used for the control applications in several area; this controller is known as the Active Disturbance Rejection Controller (ADRC); it is proposed by Jingqing Han [10].…”
