In this paper a fuzzy controller based DVR is proposed for the protection of the sensitive unbalanced nonlinear loads from sag/swell, distortion, and unbalance in supply voltage is achieved. A simple generalized algorithm based on basic synchronous reference frame theory has been developed for the generation of instantaneous reference compensating voltages for controlling a DVR. This novel algo...

Power electronic devices and variable speed drives solve a power quality issue. To increase the quality, distribution side must be compensated by concurrently infusing actual reactive power. A cost-effective method of preventing voltage sag swell in loads is use dynamic restorer. enhance for end users, DC-link component will combined with DVR. Ratings DC-Link elements inverters are more challen...

An interline dynamic voltage restorer (IDVR) is a novel c o m p e n s a t i o n piece of equipment for sag mitigation It is made of several dynamic voltage restorers (DVRs) with a common dc link, here each DVR is connected in series with a distribution feeder. In the sag period, active power is transferred from a feeder to other one and voltage sags with long durations can be mitigated. IDVR co...

In this paper, the hybrid photovoltaic-thermoelectric generator (PV-TEG) combined dynamic voltage restorer (DVR) system is proposed for power quality disturbances compensation in a single-phase distribution system. The stable and precise level of input essential smooth trouble-free operation electrically sensitive loads which are connected at utility side to avoid malfunctions. context, PV-TEG ...

The dynamic voltage restorer (DVR) combined with a photovoltaic–thermoelectric generator (PV-TEG) system is proposed for disturbance compensation in the three-phase four-wire distribution system. PV-TEG hybrid energy source used DVR to improve ability deep and long-period power quality compensation. In addition, will save grid consumption when module generates sufficient meet load demand. An en...

This paper presents a comprehensive review of various techniques employed to enhance the low voltage ride through (LVRT) capability of the fixed-speed induction generators (FSIGs)-based wind turbines (WTs), which has a non-negligible 20% contribution of the existing wind energy in the world. As the FSIG-based WT system is directly connected to the grid with no power electronic interfaces, termi...

This paper proposes a low complexity control scheme for voltage of dynamic restorer (DVR) in three-phase system. The employs the fractional order, proportional-integral-derivative (FOPID) controller to improve on DVR performance order enhance power quality terms response time, steady-state error and total harmonic distortion (THD). result obtained was compared with proportional-integral (FOPI),...
