“…Several control strategies such as coordination, control strategy, optimal predictive scheme, frequency adaptive disturbance observer, fuzzy proportional derivative and integral control are reported in the literature [30]. Some of them are applicable to unbalanced and distorted voltage conditions and some of them needs additional filters and phase locked systems.…”

Integration of renewable energy source is one of the major goals in smart grid technology. This paper proposes a pure wave distribution static compensator (PW-DSTATCOM) for achieving the grid interconnection of solar power without deteriorating the quality of power. This PW-DSTATCOM is a reactive power compensating device that improves the power quality of the distribution system. It reduces voltage sag, surge and flicker caused by rapidly varying reactive power demand. This paper presents the idea of incorporating a seven-level inverter as voltage source inverter (VSI) and inductor capacitor inductor (LCL) filter instead of inductor capacitor (LC) filter in PW-DSTATCOM. This seven-level inverter is used for solar energy conversion to make distortion less sinusoidal waveform and LCL filter is proposed for active damping. This arrangement reduces the total harmonic distortion (THD) as per IEEE 519 standard. The simulation results show that the THD of voltage is 3.00% and the current is 2.26% with the proposed method. It also enhances the system voltage stability due to ultra-fast response time. The costing and sizing of the filter is reduced considerably by using a seven-level inverter. MATLAB Simulation software is used to develop and simulate the proposed system.

“…In [20], for minimizing the total real power loss in DNs with the interfacing of DGs, plug-inhybrid electric vehicles (PHEVs), and D-STATCOM, a genetic algorithm is proposed. A control technique is developed in [21] for D-STATCOM for extracting the fundamental weight components from non-sinusoidal load currents to produce grid reference currents. For harmonics elimination, the injection of reactive power and balancing of load, this D-STATCOM is developed.…”

A Novel Three-Phase Harmonic Power Flow Algorithm for Unbalanced Radial Distribution Networks with the Presence of D-STATCOM Devices

Due to the rapid advancement in power electronic devices in recent years, there is a fast growth of non-linear loads in distribution networks (DNs). These non-linear loads can cause harmonic pollution in the networks. The harmonic pollution is low, and the resonance problem is absent in distribution static synchronous compensators (D-STATCOM), which is the not case in traditional compensating devices such as capacitors. The power quality issue can be enhanced in DNs with the interfacing of D-STATCOM devices. A novel three-phase harmonic power flow algorithm (HPFA) for unbalanced radial distribution networks (URDN) with the existence of linear and non-linear loads and the integration of a D-STATCOM device is presented in this paper. The bus number matrix (BNM) and branch number matrix (BRNM) are developed in this paper by exploiting the radial topology in DNs. These matrices make the development of HPFA simple. Without D-STATCOM integration, the accuracy of the fundamental power flow solution and harmonic power flow solution are tested on IEEE−13 bus URDN, and the results are found to be precise with the existing work. Test studies are conducted on the IEEE−13 bus and the IEEE−34 bus URDN with interfacing D-STATCOM devices, and the results show that the fundamental r.m.s voltage profile is improved and the fundamental harmonic power loss and total harmonic distortion (THD) are reduced.

“…These power quality problems have given rise to different developments, and these problems have been addressed in the literature from complementary aspects, depending on the type of compensation. Among these mitigation techniques used for power quality issues in the distribution system, it is possible to find the custom power devices (CPDs) based on the active power filter (APF), commonly used for reactive power compensation, harmonic mitigation, and balancing of source currents [3,4]. Additional devices such as the dynamic voltage restorer (DVR) are used to compensate unbalanced voltage disturbance [5,6], and unified power quality conditioners (UPQCs) are used to compensate both voltage and current quality problems [7,8].…”

This paper presents an active power filter based on a seven-level cascade H-bridge where the main contribution is a control strategy that combines model-based predictive control, the voltage vectors of the converter output levels, the phase shift PWM technique, and suboptimal DC-link voltage control. The proposed scheme greatly simplified the overall control system, making it well suited to compensate the current harmonics distortion at the grid side, generated by nonlinear loads connected to the point of common coupling. In addition, the proposed method achieved a balancing of the capacitor voltages of the seven-level cascade H-bridge converter by using the minimum DC-link voltage sensors. This feature significantly reduced the control system complexity and provided a low computational burden. Experimental results confirmed the feasibility and effectiveness of the proposed controller.
