“…Though, active filtering using DSTATCOM or D-STATCOM is normally adopted to work out grid harmonic pollution. Still, various types of designs, such as I-DSTATCOM, D-SVC-DSTATCOM and I-SVC-DSTATCOM are considered for the betterment of power delivery,which is deemed highly essential (Sabat et al, 2021;et al, 2016;Zhao et al, 2017). Due to the high effectiveness, accuracy, superiority and feasibility, an improved version of DSTATCOM, I-SVC-DSTATCOM has been carried out as a proposed approach to investigate the performance by extensive research.…”

“…So, to dampen the power oscillations, the SVC in the transmission system plays a very significant role. The load currents are mainly collected or extracted from the PCC (Mangaraj, 2021;Mangaraj et al, 2022b;Mangaraj et al, 2022c;Puhan et al, 2021;Sabat et al, 2021;Wang et al, 2017c;ZangenehBighash et al, 2018).So, here Voltage Source Inverter (VSI) or DSTATCOM is the main custom power device that can be used for the mitigation of the harmonics and other PQ issues to get a reliable power supply from the power system. The foremost objective of DSTATCOM is to control the flow of the reactive power.…”

This research study explains the design and performance of a Static VAR Compensator (SVC) coupled Hybrid Distribution Static Compensator (DSTATCOM) for low voltage power distribution system (PDS). A comparative analysisis done between Voltage Source Inverter (VSI)-based DSTATCOM and SVC Hybrid DSTATCOM using Jordan Least Mean Square (JLMS) algorithm to alleviate the shunt-related power quality (PQ) glitches. The specific design is obtained as compared to the existing neural network toolbox algorithm to improve the estimation speed and accuracy. The main objective is to extract the tuned weighted values of fundamental active and reactive power components of distorted load currents for the switching signal generation using an adaptive JLMS algorithm.Several functions of DSTATCOM and hybrid DSTATCOM using this JLMS controller are showcased for harmonics curtailment, power factor (p.f.) improvement, load balancing, voltage regulation, etc. Simulation results on an SVC Hybrid DSTATCOM have shown an acceptable level of performance under unbalanced loading situations. Finally, some comparative results are provided to validate the feasibility and effectiveness of the suggested topology.

“…However, this support solves the power quantity issues rather than PQ because almost all connected loads in an EDS are based on solid-state power electronics [1]. They inject current harmonics into the EDS and cause PQ issues at different sections of the system, such as excessive heating in coils, increased copper loss, and electrical magnetic torque in the machine producing mechanical jerk, phase cable damage, unwanted excessive current flow, distribution losses increases and difficulty in running sophisticated medical and industrial equipment [2]. To a certain extent, pollution in the environment by utilizing nonconventional sources is reduced, but, until now, PQ has been lacking [1][2][3].…”

This paper explains the experimental study of a distributed energy resource (DER) integrated three-phase, three-wire electrical distribution system (EDS) under power quality (PQ) and optimal active power flow control (OAPFC). In this research, a back-to-back connected two-level VSI (BTB-TVSI) based distribution static compensator (DSTATCOM) for unbalanced non-linear load is designed. The aim is to provide better OAPFC in EDS with shunt compensation to maintain a round-the-clock quality power supply for end users. The improved neural network-based adaptive least mean square (ALMS) control algorithms are employed for DSTATCOM. The ALMS control strategy is realized using the SPARTAN-6 field programmable gate array (FPGA) evaluation kit. This research involves the comparative study of a two-level voltage source inverter (VSI) and a BTB-TVSI in terms of their OAPFC capability and robustness in mitigating power quality (PQ) against source current disturbances, low power factor (PF), poor voltage regulation, unbalanced voltage at the point of common coupling (PCC), high switching stress, and issues in the EDS operation. The experimental results demonstrate that the BTB-TVSI using an ALMS controller is able to achieve better dynamic performance and lower total harmonic distortion (THD) under selected/permissible limits in comparison to a conventional VSI.

“…Nowadays, different topologies of power electronics-based custom power devices are available due to the launch of active power filters to reduce the power quality (PQ) issues in three-phase power utility networks (PUN) (Bayu, 2020;. In recent years, the integration of shunt compensators with low and medium voltage PUN has gained significant popularity (Bayu, 2020;Sabat et al, 2021). Clients ranging from domestic to industrial are demanding the utility companies to enhance the quality of power delivered.…”

This paper presents the shunt compensation performance of quasi-Z-source inverter (QZSI) and back to back connected QZSIs (BB-QZSI) to address the power quality (PQ) issues in the three-phase three-wire power utility network (PUN). Generally, these PQ issues are poor voltage regulation, low power factor (PF), source current distortion, unbalanced voltage, etc. The proposed BBQZSI-based distribution static compensator (DSTATCOM) consists of two QZSIs with a common dc-link capacitor. Because the QZSI could achieve buck/boost conversion as well as DC to AC inversion in a single-stage and the back to back configuration decreases the system down time cost (if a fault occurs in one QZSI the other can continue the shunt compensation). Particularly, icos ϕ control algorithmcontrol algorithm is implemented to generate proper switching pulses for the switches of DSTATCOM. The effectiveness of the BB-QZSI is verified through simulation studies over QZSI using MATLAB/Simulink software satisfying the recommended grid code.
