Universal power line manager for wind turbine generator connected to microgrid

Abstract

A wind power plant meets so many power quality issues when it is connected to a microgrid. This paper envisages a new power quality conditioner to regulate the supply frequency, to control the power flow, to minimize the current harmonics and to regulate the voltage for a fixed-speed induction-type wind generator. The proposed new power line conditioner is called the universal power line manager (UPLM). The control circuit of the UPLM is the combination of the control system of the unified power quality conditioner, power flow control and a frequency regulator. For these reasons, the compensator proposed here is called the UPLM. The complete system has been developed, analysed and validated by Matlab/Simulink study. Simulation results are presented to confirm that the new approach has a better performance for wind turbine generation.

Robust sliding mode controller for frequency regulation in a microgrid

“…The green house initiative taken by several countries is the main cause to develop various community-based isolated microgrids. The small signal model of an isolated microgrid is sufficient to analyse the frequency deviation against load deviations and intermittent nature of distributed energy resources, and several studies are also available in the literature (Eberlein and Rudion, 2021; Kumar et al, 2020; Latif et al, 2021; Paul et al, 2012; Yadav and Singh, 2021; Yang et al, 2018; Zhao et al, 2021). Thus, frequency regulation is a formidable problem in an isolated microgrid due to absence of effective coordination and power sharing among distributed generations against uncertainties, outage uncertainties and intermittency nature and so on.…”

Adaptive control of variable-speed wind energy conversion systems with inaccurate wind speed measurement

“…However, the high cost of wind energy conversion systems (WECSs) is holding up the progress of WECSs into the electricity market. Hence, novel advanced control algorithms are needed for reducing the cost of WECSs and improving power quality as well (JenoPaul, 2013; Wang et al, 2011; Yang et al, 2011).…”
