This study focuses on enhancing power quality using a Current Source Converter (CSC) based Dynamic Voltage Restorer (D-STATCOM) controlled by a Fuzzy Logic-PID (Fuzzy-PID) controller. Power quality improvement is a vital aspect of maintaining reliable and efficient electrical power systems. The integration of fuzzy logic with traditional PID control enables adaptive and precise regulation of the D-STATCOM, addressing voltage sags, swells, and harmonic distortions effectively. The Fuzzy-PID controller dynamically adjusts the control parameters, offering superior performance in compensating for power quality disturbances compared to conventional methods. Simulation and experimental results demonstrate that the Fuzzy-PID controlled CSC-based D-STATCOM significantly improves voltage stability, reduces harmonic distortion, and enhances overall power quality. This approach is particularly effective in managing the nonlinear and time-varying nature of electrical loads, making it highly suitable for industrial power systems, renewable energy integration, and smart grid applications. The proposed system ensures robust and reliable power quality improvement, presenting a promising solution for modern electrical infrastructure challenges.

The utilization of a photovoltaic-based distribution static compensator (PV-DSTATCOM) stands out as a prominent solution for addressing energy demand deficits and power quality challenges within contemporary power systems. This article focuses on enhancing the performance of PV-DSTATCOM to facilitate grid integration and elevate power quality standards. In the envisioned system, the power from the photovoltaic array is harnessed through the utilization of the sliding mode control, ensuring the extraction of maximum power. The performance of the PV-DSTATCOM is analyzed by using a Packed U cell 5 inverter. The control signals for the voltage-source inverter are generated using PQ control scheme. The efficacy of the proposed system is substantiated through MATLAB simulation results. The outcomes presented in this article highlight the accomplished improvement in the performance of PV-DSTATCOM, ensuring concurrent advancements in current THD.

“…For the purpose of producing grid reference currents, the fundamental weight components of load current are calculated using adaptive filtering algorithms, with the aim of minimizing error between the actual and estimated load currents. Some of the control schemes employed with adaptive filtering algorithms are least mean square (LMS), 15 improved versions of LMS, 16 least mean fourth (LMF), 17 normalized LMS (NLMS), 18 decorrelation NLMS, 19 leaky LMS, 20 delayed μ‐law proportionate NLMS, 21 and leaky least logarithmic absolute difference (LLLAD) 22 . In general, an appropriate cost function adapted to specific noise environments is required in developing an adaptive filtering algorithm.…”

SummaryThis paper develops a variable step size robust normalized least mean absolute third (VSSRNLMAT)‐based control scheme for a three‐phase grid‐tied multifunctional photovoltaic system (GTMPVS). The GTMPVS delivers PV power to grid‐connected loads and feeds excess power to the grid through a voltage source converter (VSC) when PV power is available. It enhances power quality (PQ) by mitigating current harmonics and compensating for an unbalanced load and reactive power simultaneously. The proposed control scheme accurately extracts the fundamental active and reactive weight components of nonlinear load current. The power exchange at the grid side occurs with balanced and sinusoidal grid currents. During the absence of PV power, the VSC continues its operation as a distribution static compensator (DSTATCOM), thus increasing the effective utilization of the power electronic switches employed in the VSC. The GTMPVS model is created in MATLAB/Simulink. The response of GTMPVS is observed under steady‐state and dynamic operating conditions while feeding power to a nonlinear load. The dynamic operating conditions are created by a change in solar irradiation and an unbalanced nonlinear load. Further, the proposed VSSRNLMAT control scheme is compared with some of the other adaptive filtering‐based control schemes, including least mean square (LMS), least mean fourth (LMF), least mean absolute third (LMAT), and normalized LMAT (NLMAT) in terms of convergence, oscillations, mean square deviation (MSD), computational complexity, and grid current total harmonic distortion (THD). It is found that the VSSRNLMAT control scheme offers THD of grid current as per IEEE‐519 standard. The proposed control scheme is implemented to operate the laboratory‐developed GTMPVS to verify the simulation results.
