This paper presents a nonlinear control method to track the maximum power point of wind turbine equipped with Squirrel Cage Induction Generator (SCIG). Since the mechanical power of wind turbine is function of its shaft speed at a given wind velocity, the proposed controller provides the desired voltage at the output of Voltage Source Converter (VSC) so as to control the generator speed and the...

This paper describes the design of controllers for a Voltage Source Converter High Voltage Direct Current (VSC HVDC) power terminal, a MIMO plant that must operate over a wide range and that experiences disturbances due to Pulse Width Modulation (PWM) switching. The controllers are designed using two approaches: the Glover–McFarlane loop shaping procedure (LSDP), and a novel implementation of a...

This paper deals with a integrated Electronic Load Controller (IELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed IELC is used to control the voltage and frequency of IAG in the integrated manner. This IELC is realised using a T-connected transformer and three-leg insulated gate bipolar tra...

According to different partitioning styles, there exist impedance-based stability analysis methods for complex systems such as voltage source converter (VSC)-based high-voltage direct current (HVDC) systems. Thus, the determination of method is importance in analysis. However, how partition a system not paid much attention past. In this paper, problems are revisited and set practical principles...

A less-intrusive solution to stabilize a voltage source converter (VSC) over an unknown grid strength is presented in this article. The existence of equilibrium point investigated as prerequisite stabilization. By partially imposing forming control, simple auxiliary outer loop proposed exhaust the physical limit power delivery steady state and provide support fault-ride-through (FRT) operations...

Abstract: In recent years, the increasing penetration level of wind energy into power systems has brought new issues and challenges. One of the main concerns is the issue of dynamic response capability during outer disturbance conditions, especially the fault-tolerance capability during asymmetrical faults. In order to improve the fault-tolerance and dynamic response capability under asymmetric...

This paper presents a comprehensive analysis of the harmonic sources single-phase grid-connected voltage source converter (VSC), which leads to an alternative approach for DC bus control VSC under grid distortion with significant switching dead time. A selective current controller zero-reference structure plays vital role in rejecting components reference created by loop and caused Therefore, c...

With the development of a distributed generation, direct current (DC) load and energy-storage equipment, voltage-source-converter-based medium-voltage DC systems (VSC-MVDC) have attracted more attention due to its low power consumption, high reliability, independent control so on. However, VSC-MVDC has problem fault isolation, which requires fast-acting circuit-breakers isolate faulty lines ens...
