“…1. D-STATCOM schematic diagram[10] D-STATCOM output AC voltage side (Vc) is adjusting to the desired voltage. D-STATCOM absorbs reactive power if the system voltage (Vs) magnitude at PCC is higher than the desired voltage; while if the voltage magnitude at PCC is smaller than the desired voltage, reactive power is injected into the system to increase its voltage; and if the system voltage is equal to the desired voltage, the D-STATCOM is not injecting or absorbing any reactive power[11].…”

Power quality problems in electric systems are one of the important topics that occupy a wide area of interest to researchers and engineers. The increased use of power electronics circuits has led to improve efficiency and performance of the equipment; on the other hand, they withdraw a non-sinusoidal current and increase the harmonics which causes a decrease in the power quality. Also, these electronic devices are sensitive to power quality problems. However, advanced electronics can be employed to mitigate these problems. The Distribution static synchronous compensator (D-STATCOM) is one of the Custom Power Devices (CPDs) used for this purpose. D-STATCOM can be designed with different topologies, algorithms, and techniques of control to mitigate various power quality problems that face the power system. Selecting the D-STATCOM design depends on the power quality problem that needs to be mitigated. This paper presents a literature review of D-STATCOM from its beginnings to the present day.

“…Solar and wind energy are the leading RESs according to the amount of energy installed but are not problem-free. For example, if these energy sources are disconnected during severe contingencies or disturbances, there could be serious challenges to the supply of reactive power, leading to difficulties in maintaining bus voltages within acceptable ranges [3] and constraints to power transfer [4], which can lead to voltage instability [5]. These RESs are interfaced into the system using converters, which have a non-linear behaviour [6][7][8] and are sources of harmonics.…”

In this study, the author presents the results of a survey on the utilisation of a dynamic voltage restorer (DVR) in power systems to alleviate voltage problems that result in sags, swells and fluctuations in voltage outside the required steady limits. A methodology based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement is adopted for conducting and reporting on the review, while the Scopus database is used to locate the relevant publications. A total of 68 publications qualify for inclusion in the survey. A bibliometric analysis covering the number of publications per annum, the top 10 most-cited journals and the top 10 most-cited publications is performed. The information from the selected publications is extracted, summarised and categorised into network scenarios for the use of DVRs, topologies and optimisation of DVRs; strategies for DVR controllers; and platforms that evaluate the feasibility of DVR topologies and controllers. Moreover, research trends and gaps are evaluated. Finally, potential areas for future research are proposed. This study provides an overview of the research on the use of a DVR to resolve voltage problems and is a resource for researchers generally interested in distributed flexible AC transmission systems (DFACTSs) and particularly interested in DVRs.

“…The decline of voltages at load terminals are among the most popular power quality issues today [8]. A voltage drop happens whenever the operating voltage falls below its real rating due to the load's excessive reactive power consumption [9].…”

The efficiency of electrical distribution systems is being more affected by the increase in voltage drops and power losses. These issues of voltage drop and power loss can be significantly minimized by the incorporation of a Distribution Static Compensator (DSTATCOM) in the distribution network. However, inappropriate positioning and sizing of DSTATCOM can undermine its efficiency. Despite the contributions of many researchers to the optimal placement of DSTATCOM and other compensators in distribution networks, the problems of voltage drop, power losses, and power quality persist, necessitating the need for additional research in this area. In this paper, an innovative technique based on hybridized Immune and Genetic Algorithm (IA-GA) for optimal DSTATCOM placement and sizing for three distinct load levels is proposed. Simulation and analysis of the proposed algorithm were carried out using IEEE-33 bus radial distribution network (RDN) in MATLAB. The simulation results demonstrate a substantial decrease in power loss and a significant improvement in the voltage profile. Evaluation of the proposed method against existing techniques reveals that the proposed technique outperforms IA and PSO in terms of decreasing power loss and enhancement of voltage profiles. A cost-benefit analysis was performed, and it was discovered that the proposed technique yields improved annual cost savings.
