“…The approach demonstrates promising performance in mitigating various power quality issues under various types of disturbance such as asymmetric, and symmetric voltage sag and harmonic. On the other hand, second-order -SOGI (SO-SOGI) is reported in [37]. The method aims to achieve fast power quality compensation with and without phase jump at harmonic conditions.…”

This paper represents a review of the dynamic voltage restorer for power quality improvement in the electrical distribution system. Over the past 50 years, issues concerning power quality have steadily increased, to prevent the effect of the voltage disturbances, some of the devices are put as a solution to these problems such as distribution static compensator (D- STATCOM), solid-state transformer (SST), uninterruptible power supply (UPS), dynamic voltage restorer (DVR). The DVR is one of the economic solutions to overcome the voltage disturbances like voltage sag/swell and harmonics. It is widely used to mitigate the voltage disturbances in the power distribution system, especially in the medium and low distribution networks. This paper aims to review the implementation of the DVR in the system integrated with renewable energy resources. This is important because the future of electricity business is moving towards renewable energy and also provides a thorough discussion of the typical components, controllers, compensation methods, and the application of DVR. The extensive review of the technology aims to ease and speed up the development and the advancement of the DVR in the near future.

“…If the second and third elements in Equation ( 8) are considered, the orthonormal basis in Hilbert space constructed by these two elements has a corresponding relationship with the plane rectangular coordinate system in Euclidean space, and these two elements are corresponding to two unit vectors l and m of two-dimensional Euclidean space. Based on the above relationship, if we define x = θ a , e q10 in Equation ( 20) can be expressed as the following vector form (25) The control laws forp 0 can be expressed as the dot products of e q10 and certain vectors as…”

“…Among the generalized integrator (GI)-based solutions, references [22][23][24] proposed DSOGI-PLL or DSOGI frequency-locked loop (FLL) to suppress the higher-harmonic voltages by adding a third integrator to reject the DC-offset voltages. Yada and Kumar [25] proposed dual SO-SOGI to eliminate the DC-offset voltages and reduce the higher-harmonic voltages. Zhang et al [9] proposed mixed SOGI and third-order GI to eliminate the DC-offset voltages.…”

When three-phase voltages are polluted with unbalance, DC offsets, or higher harmonics, it is a challenge to quickly detect their parameters such as phases, frequency, and amplitudes. This paper proposes a phase-locked loop (PLL) for the three-phase non-ideal voltages based on the decoupling network composed of two submodules. One submodule is used to detect the parameters of the fundamental and direct-current voltages based on Tan-Sun transformation, and the other is used to detect the parameters of the higher-harmonic voltages based on Clarke transformation. By selecting the proper decoupling vector by mapping Hilbert space to Euclidean space, the decoupling control for each estimated parameter can be realized. The settling time of the control law can be set the same for each estimated parameter to further improve the response speed of the whole PLL system. The system order equals the number of the estimated parameters in each submodule except that a low-pass filter is required to estimate the average amplitude of the fundamental voltages, so the whole PLL structure is very simple. The simulation and experimental results are provided in the end to validate the effectiveness of the proposed PLL technique in terms of the steady and transient performance.
