This paper uses super capacitor as the energy storage device for the DVR to compensate voltage sag, voltage swell and harmonics due to addition of nonlinear load in the distribution line. Based on this topology, DVR consist of super capacitor, z source inverter and injection transformer. Super capacitor produces the necessary dc voltage which is given as the input voltage to the z-source inverter; provide the necessary injecting voltage, which has to be restored. A new topology based on Z-source inverter is presented in order to enhance the voltage restoration property of dynamic voltage restorer. Z-source inverter would ensure a constant DC voltage across the DC-link during the process of voltage compensation. The modeling of Z-source based dynamic voltage restorer is carried out component wise and their performances are analyzed using MATLAB software

Voltage sag and swell have a major concern in the distribution systems. In order to mitigate the voltage sag and swell, a custom power device called dynamic voltage restorer (DVR) is used. The proposed system is a polymer electrolyte membrane (PEM) fuel cell based DVR. The energy from the fuel cell is stored in the super capacitor to restitute the voltage. In this proposed DVR, Z-source inverter is used instead of traditional inverter because of buck-boost and shoot through capability. The simulation is performed using three controller topologies: PI controller, synchronous reference frame controller and fuzzy controller and the results are verified using Matlab-Simulink environment.

<p>The maintain power quality is one of the major part of all kind of industry as well as power systems. Voltage sag and voltage swell the common power quality issue. The Dynamic Voltage Restorer is the common Device which is used to mitigate the above problems. In this paper provides review on various type of AC-AC converter based DVR. The use of AC-AC converter can compensate the voltage sag and swell without need of any kind of storage elements like capacitor and batteries. The absence of storage elements can reduce size and weight of the DVR. The feature various type of AC- AC converters based DVR is concentrated in this paper.</p>

Power quality is a big challenge nowadays. Various disturbances present in the power system are voltage sag, voltage swell, harmonics, transients, interruptions, voltage collapse etc. To solve the problem of power quality, various custom power devices are generally used in a power system, dynamic voltage restorer (DVR) being one of them. DVR is used for the compensation of voltage sag and swell. In this paper, a model of DVR with molten carbonate fuel cell (MCFC) and Y source inverter is proposed. The proposed model is compared with the existing ones to check its performance characteristics. MATLAB/SIMULINK was been used to check and compare the performance of the proposed with existing models.

Voltage sag and voltage swell are frequently occurred power quality problems in present power distribution system, which are cause more problems to avoid these problems and maintain constant voltage at sensitive load during sag and swell Dynamic voltage restorer gives solution .we propose self-supported DVR, to minimize the cost by preventing external dc source in DVR, it is controlled by SRF PI control along with an inner current loop to stabilize the system and outer voltage loop to increase the system robustness. The proposed model provides fast voltage restoration for a short and long duration of voltage sags and swells manage wide load current variation for short and long voltage disturbances. In this paper, we present the effectiveness of the proposed method by using MATLAB/simulation results. A laboratory prototype DVR is modelled and we are using CCS studio to interface DSPTMS320F28027F

All customers require quality voltage, quality current and quality power from the utility, but usage of nonlinear loads generates voltage sag, swell and harmonics. This work examines the solar energy based various topologies like 3-Leg, 4-Leg, and 6-Leg Dynamic Voltage Restorer (DVR) for minimizing the voltage swell. To get most prominent power from the solar system Perturb & Observe (P&O) scheme is also used. The most famous topologies are approved utilizing MATLAB/SIMULINK programming to limiting voltage swell. The gained results are comparable nonetheless even possibly better in 6-leg PV-ZSI-DVR diverged from 3-leg and 4-leg PV-ZSI based DVRs.
