“…Leading the charge for green energy investment, solar photovoltaic (SPV)-integrated DSTATCOM topologies have gained prominence in recent times, contrasting with selfsupporting DSTATCOM topologies [4] [6]- [15]. The latter, documented in the literature, involves withdrawing active power from the grid to maintain the dc-link capacitor voltage.…”

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.

SummaryThe advantage of a generalized electric spring (G‐ES) is that it solves the redundancy problem of a conventional electric spring (ES) in the face of critical load clusters. This paper first introduces Hamilton's principle into the G‐ES, derives the mathematical model of the G‐ES, and further introduces the topology of the G‐ES. Next, the working modes and working states of the G‐ES are defined. The working modes are used to reflect the combination of ES power inside the G‐ES, and the power conditions in specific working modes are described using a phase diagram. Then, the paper analyses the power case of the G‐ES to the external system, giving the respective working states according to their internal working modes. Finally, this paper introduces PQ control to the control strategy of the G‐ES and achieves control of the G‐ES working mode and its working state. The results of the study show that there are 100 working modes of the G‐ES, and 76 working modes have a specific working state. The correctness of the working mode and working state analysis is verified with the help of the MATLAB/Simulink simulation and experiment.
