In this article a comprehensive control of a wind turbine system connected to an industrial plant is developed. The algorithm utilizes a structure of the back-to-back converter where two modes of operation can be achieved. During the connection of the wind turbine (mode I), the utility side controller is designed to compensate the harmonics caused by the nonlinear load, in addition to the active and...
This paper deals with a voltage and frequency controller (VFC) of a stand-alone wind energy conversion system using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The reference generator currents are estimated using the power balance theory to control the voltage and frequency of IAG system. Two-leg reduced switch integrated voltage source converter (VSC) with a battery...
In this paper, a battery energy storage system (BESS) based voltage and frequency (VF) controller based on isolated three-leg VSC with a zig-zag transformer is proposed for stand alone power generation using a permanent magnet synchronous generator (PMSG). An isolated distributed generation (DG) system is realised using fixed pitch wind turbine. The proposed stand alone wind energy conversion system...
This paper deals with an application of the power balance theory in a voltage and frequency controller (VFC) of an autonomous wind power generation using an isolated asynchronous generator (IAG) feeding three-phase four wire loads. The reference generator currents are estimated using the power balance theory to control the voltage and frequency of IAG system. Three-leg voltage source converter (VSC)...
In this paper, an autonomous wind energy conversion system (WECS) is proposed using a permanent magnet synchronous generator (PMSG). The voltage and frequency (VF) of the stand alone WECS is controlled using a voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link. A Scott-connected transformer is proposed for the neutral current compensation of the three-phase four-wire...
Integration of wind turbine and UPQC (unified power quality conditioner) results in providing active power for UPQC to solve deep voltage sag and voltage interruption and also transferring generated power of wind turbine to the network. In this paper, the possibility of active power control is added to the control system of series and shunt parts of UPQC, so that delivering of active power via each...
