“…But in DC-DSTATCOM, the point of common coupling (PCC) possesses various severities due to the direct connection of DSTATCOM, supply and load. Hence, flow of short circuit current, poor protection, some thermal losses are occurred [5]- [8]. Due to these drawbacks of DC-DSTATCOM, nowadays the development was started in the area of inductively coupled distributed static compensator (IC-DSTATCOM).…”

In this research paper, an inductively coupled distributed static compensator (IC-DSTATCOM) for three phase three wire (3P3W) electric power distribution system (EPDS) is proposed. The contraction of power quality (PQ) was marked as a perilous droop mode bump into direct coupled distributed static compensator (DC-DSTATCOM). To regain the PQ, inductive coupling transformer is assisted in conjunction with DC-DSTATCOM. The system equivalent circuit of IC-DSTATCOM is accomplished by take into account of impedance of both transformer and DC-DSTATCOM to reveal the filtering technique. The filtering icos∅ mechanism is performed by following the generalized mathematical approach using MATLAB/Simulink. A case education is reviewed in detail to illustrate the performance of both DC-DSTATCOM and IC-DSTATCOM. The IC-DSTATCOM is amplified healthier as compared to other in terms of harmonics shortening, good power factor, load balancing, and potential regulation. To examine the effectiveness, simulation outputs of the IC-DSTATCOM with different PQ parameter indices are presented by following the benchmark measure of IEEE-2030-7-2017 and IEC-61000-1 system code.

“…The DSTATCOM can be configured to solve PQ problems such as harmonics filtering, reactive power compensation, voltage support in low‐voltage distribution networks, load balancing, and lowering SPV power fluctuations using several control algorithms. These algorithms include synchronous reference frame theory (SRFT), 10 P‐Q theory, 11 salp swarm optimization algorithm (SSOA), 12 cascaded enhanced second‐order general integrator with a prefilter (CESOGI‐WPF) control technique, 13 LCL‐filter‐based DSTATCOM, 14 ANOVA Kernel Kalman filter (AKKF), 15 Hermite function‐based ANN, 16 optimized multi‐layer perceptron (MLP) neural network, 17 Bernoulli polynomial‐based control technique, 18 proportionate affine projection algorithm (PAPA), 19 Laguerre polynomial (LP)‐based algorithm, 20 instantaneous symmetrical components theory (ISCT), 21 normalized least mean absolute third (NLMAT) algorithm, 22 and immune feedback control algorithm 23 . The DC link of the DSTATCOM can also be used to interface solar photovoltaic (SPV) arrays to extract DC power to three‐phase system 24 .…”

SummaryThis paper proposes leaky least mean fourth (LLMF) algorithm for the control of five‐level series connected H‐bridge multilevel inverter (5L SCHB‐MLI). The SCHB multilevel inverter is a popular configuration due to its wide application for high‐power and medium‐voltage applications. The complete system comprising the grid, load, and compensator is modeled in MATLAB/SIMULINK. Prototype hardware is also developed in the laboratory for experimental validation. The 5L SCHB inverter is connected in a single‐phase power distribution system and controlled as a compensator. The voltage across both DC links of the H‐bridges is regulated to almost equal value by the proposed control algorithm. The closed loop system is designed to mitigate total harmonic distortion (THD) in the source current and improve the power quality of the proposed system. The system is analyzed under the steady state and dynamic state, and the results are also verified on the hardware prototype developed in the laboratory. The proposed algorithm is also compared with conventional least means square (LMS) algorithm and notch filter algorithm on several parameters. The paper discusses a detailed simulation and hardware analysis on the control of five‐level MLI topology.
