“…Most of the existing methods for controlling voltage phase and amplitude include FACTS devices [9], such as the Static Synchronous Compensator (STATCOM) [9,28], Unified Power Flow Controller (UPFC) [29], Unified Power Quality Conditioner (UPQC) [30] and the Dynamic Voltage Restorer (DVR) [11][12][13]. In most cases these devices use AC/DC/AC converters with DC-energy storage (electrolytic capacitors, batteries, etc.).…”

“…Another well known device to improve voltage parameters is DVR. Conventional DVR is based on an AC/DC/AC converter [11][12][13]. The DVR can be equipped with DC energy storagethe energy for compensation is taken from the storage unit -or it can operate without energy storage -the energy for compensation is taken from the power grid.…”

“…However, in order to realize these functions another four bidirectional switches in each phase are required. An often encountered circuit for voltage sag/swell compensation is the DVR (Dynamic Voltage Restorer) [11][12][13][14][15]. The conventional topologies of DVR are based on AC/DC/AC converters with DC energy storage.…”

“…The use of FACTS devices such as STATCOMs, SVCs and TCR have revolutionized the power industry. The use of the Dynamic Voltage restorer (DVR) has been studied extensively in mitigating disturbances in voltages on the power system such as voltage sags, swells, unbalance and harmonics in the supply voltage [10][11] [12]. Its use has also been investigated in the fault ride through of specific sources of power like wind turbines that are required by grid codes to remain connected to the system on the occurrence of a fault in the grid [13] [14].…”

This paper deals with the issues related to the interconnection between the microgrid and main network. The Dynamic Voltage Restorer (DVR) is proposed as an interface between the main network and microgrid in order to improve reliability and limit fault currents. The performance of DVR is demonstrated during fault conditions in two different locations, firstly in the main grid and then within the microgrid. The DVR is used to inject a voltage during a fault in the main grid isolating the microgrid from the fault and ensuring normal operation. Secondly, a novel technique is proposed employing the magnetizing inductance of the DVR series transformer in order to minimize the contribution of the grid currents during a fault within the microgrid. The proposed technique is evaluated using MATLAB/SIMULINK and shown to possess additional advantages when compared to traditional fault current limiters.

Summary This paper presents T‐type multilevel inverter topology‐based dynamic voltage restorer (DVR) with reduced switch count. In medium voltage and high‐power applications, two‐level voltage source inverters are insufficient because of more voltage stress on switches, large dv/dt, size, and cost of the filter. To overcome these problems, multilevel inverter‐based DVR is suitable, which can be directly connected to the medium voltage distribution system without injection transformer. In addition, the control of the DVR is implemented by abc to dq controller. The voltage compensation capability of the proposed DVR is enhanced by employing the in‐phase compensation technique with reduced carrier pulse width modulation scheme, and also the total harmonic distortion(THD) in the load voltage is reduced. The design and analysis of the proposed system are discussed, and its performance is validated in MATLAB/Simulink and in the OPAL‐RT real time processor.
