The article presented here utilizes the particle swarm optimization (PSO) and water cycle algorithm (WCA) based dynamic voltage restorer (DVR) to augment low ride through (LVRT) performance of a hybrid renewable energy system (HRES). Moreover, FACT equipment like is deployed boost quick responsiveness compensation good transient HRES. Due numerous disturbances brought on by WECS' nonlinearity, ...

This paper investigates the power quality problems which occur frequently in supply and suggests a method to mitigate by implementation of UPQC. P-Q generally concern with voltage sags/swells harmonic currents. Custom Power (CP) devices that these have gained more attention recent decades. UPQC is Designed, modelled setup experimentally sag/swells currents three phase systems. consists Dynamic ...

In a modern power system, the unified quality conditioner (UPQC) is considered to be most effective device for mitigating problems. The use of dynamic voltage restorer (DVR) active-reactive power-sharing reduces loading on UPQC in all operating conditions, leading better system efficiency and reliability. VA DVC can controlled by maintaining proper angle between load source voltage. this paper,...

This paper deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR). The DVR is a dynamic solution to protect sensitive loads against voltage sags and swells. The DVR can be implemented to protect a group of medium voltage or low voltage consumers. The new configuration of DVR has been proposed using improved d-q-0 controller technique. This study presents compensation of...

In order to utilize Doubly Fed Induction Generators (DFIGs) as primary power source in an isolated system, they should be able to regulate the voltage and frequency of the system as well as ride-through faults. This paper proposes a new control strategy for a DFIG operating in an isolated power system, accomplished by a Dynamic Voltage Restorer (DVR) and a Supercapacitor Energy Storage System (...

This work confers the simultaneous analysis of voltage and frequency control 3-area interconnected hybrid power system (IHPS) consisting parabolic-trough solar (PSP), wind (WPS) dish-stirling (DSP) under paradigm microgrid. The speculated result IHPS is presented analyzed considering real reactive as function both frequency. 9The proposed investigation has been mathematically modeled for direct...

Voltage sag is one of the most severe power quality disturbances to be dealt with by industrial sector, as it can cause process disruptions and results in substantial economic loss. A short-term decreasein voltage lasting anywhere from milliseconds up a few seconds called sag. At present, wide range very flexible controllers, which capitalize on newly available electronics components, are emerg...
