    The incorporation of clean sources into the power grid, along with the introduction of power electronic gadgets to regulate loads that are nonlinear, had a significant effect on power quality (PQ). Nevertheless, PQ emerges as the primary issue for the integration of these intermittent renewable sources. This study combines the advantageous characteristics of the Sliding mode controller (SM-C) and fractional-order proportional integral derivative controller (FPIDC) to manage both the shunt and series active filters of the Unified Power Quality Conditioner (UPQC) integrated with the wind power system (WPS) and battery systems (BS). The primary objective of the proposed system is to maintain a consistent voltage across the DC Link capacitor, even when there are fluctuations in load and wind velocity. Additionally, the system aims to reduce the presence of harmonics in waveform of current signal, improve power factor (PF), and mitigate any disruptions or imbalances in the source voltage. The effectiveness of the created model has been assessed by four case studies involving diverse load types and grid voltage situations, including fluctuations. Besides, to validate the developed method the comparative analysis is conducted with respect to other methods like PI and fuzzy logic controllers, as well as with other ways documented in the literature.

    Analysis of ludo-shaped configuration of PV arrays under different partial shaded configuration
    (Springer Science and Business Media Deutschland GmbH, 2024) Ganesan, Sakthivel; David, Prince Winston; Thangaraj, Hariharasudhan; Balachandran, Praveen Kumar; Çolak, İlhami
    The demand for electric power generation increases every day. Electric power is generated through using thermal, hydro, thermal, and nuclear energy and so on. However, the availability of these resources made us to depend on renewable energy sources for power generation. The PV arrays are installed in lot of applications either by grid connection or by stand-alone. Partial shading conditions cause less power generation from the PV arrays when compared to normal power generation. In this proposed work, an experimental setup of a 4X4 PV array is considered for analysis and LUDO shaped reconfiguration pattern is considered under different partial shaded conditions, the power losses and mismatch losses are found. When the compared with the existing methods the proposed method reduces the mismatch losses and thereby the power is enhanced twice in inverse short shading pattern. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

    Performance evaluation of PI and FLC controller for shunt active power filters
    (Springer science and business media deutschland GmbH, 2025) Annamalaichamy, Arulkumar; David, Prince Winston; Balachandran, Praveen Kumar; Çolak, İlhami
    Shunt active power filters (SAPF) play a vital role in power systems. Integration of renewable energy sources and electrical vehicle (EV) charging stations proliferate in the modern power system. In such scenario, SAPF is an efficient method for improving power quality. The article suggests a SAPF with multilevel cascaded H-bridge inverter using the instantaneous real and reactive power (P–Q) theory based control technique to derive reference currents for the compensation unit from active and reactive power to suppress harmonics present in the power system. The conventional-proportional integral (PI) and intelligent-fuzzy logic controller (FLC) were used as voltage controllers for maintaining the DC link voltage. The article proposed an aggregated PWM signal-switching circuit for balancing the individual capacitor voltage. The proposed system harmonic results are compared with conventional triangular PWM and aggregated PWM. The proposed switching circuit balanced the individual capacitor voltage and minimized the total harmonic distortion (THD) in the sinusoidal source voltages and currents. Simulation and prototype results reveals that proposed aggregated PWM system with FLC dominates the conventional PI controller.
