“…Based on the functioning, a DVR modes of operation are divided in to three modes, which are, Protection, Standby and voltage injection [21], [32]. In protection mode, Exceeding the load current over permissible value due the short circuit or large inrush current, DVR will be isolated from the power system using SW2 and SW3 as shown in Figure 1 and thus providing an alternative path for the load current flow through SW1.…”

“…"Dynamic Voltage Restorer" (DVR) help in resolving problems of a power system that has voltage disturbances. it is an active inverter that adjusts the voltage, either through a transformer or without a transformer in series and in synchronization with the grid at the point of common coupling (PCC) [20], [21]. Calculation of the compensation voltage is done by comparing the reference load voltage and the actual voltage of the grid.…”

“…The main concern in utilizing DVR is the efficient control of DVR when injecting real and reactive power [22]. In a DVR, the main functions of the control system are to identify the voltage drops or swells, to generated voltage reference signal, controlling converter and the protection of the system [21], [23]. The quality and accuracy of the detection methods will have a big impact on the performance of the control algorithm .…”

Nowadays, power quality under the excessive implementation of power electronics devices is quite challenging issue. The compensation of non-sinusoidal; reactive and harmonic; components is the main role for power quality devices which highly depend on the robustness of the control system. Some common control systems are implemented using DQ theory. This paper proposes a new version of DQ control technique to control dynamic voltage restorer under severe transient voltage conditions. The power system network with the new DQ control technique is studied and analyzed under different scenarios to compensate for severe balanced and unbalanced voltage sags and swells. This new scheme is based on extraction of positive sequence components to implement the control algorithm. A mathematical model of the DVR, hysteresis voltage control, converter controller model, new DQ scheme with complete system equations are carried out and verified using Simulink / MATLAB. The proposed system is validated experimentally using DSpace 1104 based laboratory system. The obtained results of the proposed compensation algorithm are compared with the results obtained from the traditional DQ method. Simulation and experimental results are correlated and show effectiveness of the proposed DQ control scheme.

“…To have proper control, a perfect reference generation technique must be implemented. Various approaches for reference generation have been suggested, including, Clark's and Park's transformations, Phasor parameter and, Symmetrical components, Instantaneous real and reactive power [20]. Park's transformation is a mathematical transformation approach used to simplify the analysis of three-phase circuits is direct-quadrature-zero (dq0) in electrical engineering.…”
