In this paper a Dynamic Voltage Restorer (DVR) is used for power quality improvement on transmission side for the voltage regulation, grid stabilization and efficient utilization. The DVR normally installed between the source voltage and critical or sensitive load. The vital role of DVR depends on the efficiency of the control technique involved in switching circuit of the inverter. The DVR is ...

The performance of D-STATCOM depends on capacitor voltage regulation. In D-STATCOM, the nonlinear controller is preferred to linear controller. Regulating and fixing the capacitor DC voltage in DSTATCOM can improve the system dynamic such as capacitor voltage response, current response and modulation index. The regulation of DC capacitor voltage based on optimal PI co-efficient. In conventional...

The performance of a chaotic micro resonator is improved by redesigning a quadratic controller reported in a previous study. The chaotic micro resonator is composed of an electrostatic actuator and a voltage regulator (controller). The actuator is made of cantilever beam electrode above a fixed electrode. The actuator voltage, and consequently the electrostatic force magnitude, is controlled to...

Because wind generators (WGs) in a wind power plant (WPP) produce different active powers due to wake effects, the reactive power capability of each WG is different. This paper proposes a hierarchical voltage control scheme for a WPP that uses a WPP controller and WG controller. In the proposed scheme, the WPP controller determines a voltage error signal by using a PI controller and sends it to...

Executive Summary In addition to the research and experimentation need to understand the basic control features of an SVC, much effort was also expended on learning the Matlab simulation software. While the Matlab SimPowerSystems and Simulink libraries contain many easily recognizable built-in control blocks, learning how each block worked required careful study and much experimentation. Even t...

Voltage-lift is a widely used technique in DC–DC converters to step-up output voltage levels. Several traditional and advanced control techniques applicable power electronic (PEC) have been reported utilized for voltage-lift applications. Similarly, recent years the implementation of fractional-order controllers (FOC) PEC applications has gained interest, aiming improve system performance, vali...
