Modeling and robust control design of astandalone wind-based energy storagegeneration unit powering an induction motorvariable-displacement pressurecompensatedpump

Abstract

This paper presents a the application of the sliding mode controller (SMC) for induction motor drive variabledisplacementpressure-compensated pump (VDPC) system powered by an isolated wind/storage unit. The variable-speedwind turbine (WT) is proposed to drive a permanent magnet synchronous generator (PMSG) which feeds a storing energyunit and stand-alone dynamic load. Energy storage systems are required for power balance quality in isolated wind powersystems. Initially, the holistic model of the entire system is achieved, including the PMSG, the uncontrolled rectifier, thebuck converter, the storage system, induction machine and the VDPC pump.

Existing method

The existing method describes The variable structure control strategy using the sliding mode hasbeen focused on many studies and research for the control of thewind generation systems. The sliding mode control canoffer many good properties, such as good performance againstun-modeled dynamics, insensitivity to parameter variations,external disturbance rejection and fast dynamic response.These advantages of the sliding mode controller (SMC) may beemployed in the speed control of the induction motor (IM).

Proposed method

The proposed method describes controller design and simulation of isolatedgeneration unit including variable speed wind- storing energysystem powering dynamic load based on sliding mode control areproposed. The power needed by the IM-variable-displacementpressure-compensated pump (VDPC) pump load can be effectivelydelivered and supplied by the proposed power generation systemsusing the proposed sliding mode control.
