  • Optimized Power Quality in Grid Systems Using PV-Based UPFC and Advanced ANN Control Approach
    Gadupudi Lakshminarayana, Sreedevi Saravanakumar, Malapati Venkateswarlu, Thankaraj Retna Bai Premila
    Journal of Renewable Energy and Smart Grid Technology, 2026
    Nowadays, grid power losses and Power Quality (PQ) issues are inducing various problems in power systems, which need to be addressed and rectified for attaining enhanced and smooth functioning. These PQ issues are generated as a result of differing values between generated and load power, which further produces fluctuations within the power supply. Hence, to overcome these limitations, an innovative control approach is proposed for attaining optimum power flow by using a Unified Power Flow Controller (UPFC). The proposed UPFC is combined with an Artificial Neural Network (ANN) controller for improving the performance efficiency of the UPFC. The ANN controller-aided UPFC rectifies the PQ issues, including sag and swell. Additionally, to provide a consistent and unlimited power supply to the DC link, a photovoltaic (PV) system is incorporated with a single-switch boost-Cuk (SSBC) converter for boosting the PV power generation process. For attaining maximum power extraction and tracking maximum power, a new Pelican Optimized Recurrent Neural Network (RNN)-based Maximum Power Point Tracking (MPPT) technique is utilized. Furthermore, to validate the proposed model, MATLAB/Simulink is utilized and the obtained results depict improved PQ with reduced losses. Therefore, the overall system attains improved power quality, thereby, enhancing the power system functioning.

    Ssrg International Journal of Electrical and Electronics Engineering, 2025
    Climate conditions that cause Power Quality (PQ) issues greatly affect the electricity produced by Renewable Energy Sources (RES), such as Photovoltaic (PV) systems, which need quick adjustment of energy transmission and distribution systems. To mitigate reactive power compensation and lower voltages well, sag, and Total Harmonic Distortion (THD), the Distribution Static Synchronous Compensator (DSTATCOM) is exploited. The function of DSTATCOM is effectively managed by a Decoupled Neural Network (DNN) controller. The DSTATCOM receives the power from the PV system, and its voltage is enhanced by an improved cascaded boost converter. Furthermore, the Horse Held Optimization (HHO) based Fuzzy Maximum Power Point Tracking (MPPT) is employed to track peak power from the PV system. MATLAB/Simulink platform is employed to assess the validation of the developed DSTATCOM with the control method under the rated capacity of distribution generation. Finally, the findings in this research demonstrate the enhanced performance of PV-DSTATCOM while ensuring grid integration and improved PQ with Total Harmonic Distortion (THD) values of 1.10%, 0.71%, and 1.06%.

    Problems of the Regional Energetics, 2025
    The main objectives of the study are to improve power quality (PQ) in grid-connected systems and mitigate voltage disturbances by using a dynamic voltage restorer (DVR) powered by a Photovoltaic (PV) system. By integrating PV as the primary power input, the DVR supplies clean energy for voltage restoration, thereby enhancing system efficiency and reliability. This approach provides transition to sustainable energy practices by minimizing the dependency on traditional power grid during disturbances. These objectives were achieved by integrating a Switched Inductor Cascaded Boost Converter (SICBC) for efficient voltage boosting and employing a Pine Cone Optimized Proportional-Integral (PCO-PI) controller for precise output regulation. The SICBC provides provide high and stable voltage gainwith improved conversion efficiency, essential for maintaining DVR performance at PV power fluctuations. The cascaded configuration mitigates stress on passive elements, contributing towards better thermal management and longer system life. By adopting the Pine Cone Optimization algorithm, the controller's parameters are fine-tuned to achieve optimal performance in terms of settling time, steady-state error and overshoot. The algorithm mimics the natural seed dispersal behavior of pine trees to explore and exploit the control parameter space effectively. The most important results are a recorded efficiency of 97.9% and a reduction in Total Harmonic Distortion (THD) to 2.56%, as demonstrated through MATLAB/Simulink-based simulations.Furthermore, the system demonstrated robust voltage compensation during both symmetric and asymmetric fault conditions. The obtained result revealsthe proposed DVR-PV strategy substantially improves power stabilityand quality, reinforcing the practical viability of renewable-integrated compensators in modern electric grids.
  • Solving Optimal Power Flow Using Enhanced Dung Beetle Optimization Algorithm
    Ravi Kumar Avvari, Lakshminarayana Gadupudi, Anil Kumar Annamraju, Nareddy Nageswara Reddy
    2025 IEEE 2nd International Conference on Green Industrial Electronics and Sustainable Technologies Giest 2025, 2025
    In this paper, an enhanced dung beetle optimization (EDBO) method is suggested for the solution of optimal power flow (OPF) problem. The EDBO method draws inspiration from the reproductive, ball-rolling, dancing, foraging, and thieving behaviours exhibited by dung beetles. By considering both local and global exploitation, the proposed method possesses the qualities of a rapid convergence rate and adequate solution precision. Along with equality and inequality constraints, the total generation cost, emission, active power loss, and magnitude of voltage deviation are considered as objectives in this paper. The efficacy of the proposed method is evaluated utilising the IEEE 30bus system. This paper employs a penalty-based constraint handling approach to effectively handle equality and inequality constraints inherent in the OPF issue. The outcomes obtained by the EDBO are contrasted with the basic dung beetle optimization (DBO), artificial hummingbird algorithm (AHA), and grey wolf optimization (GWO) algorithms. From results it is evident that the EDBO exhibits superior performance with regard to convergence rate, solution accuracy, and stability as compared to other algorithms.

    Proceedings of 2024 2nd International Conference on Recent Trends in Microelectronics Automation Computing and Communications Systems Exploration and Blend of Emerging Technologies for Future Innovation Icmacc 2024, 2024
    The growing apprehension over global warming, along with rising energy needs, has propelled the traditional power infrastructure towards greater reliability through integration of renewable energies into grid. Incorporating renewable energies into grid presents numerous challenges. Throughout the day, the output power of the photovoltaic systems fluctuates. This paper elucidates how various power factors on the load side affect the entire system. Several simulation cases are conducted using different power factors to analyze the impact on the entire grid-integrated PV system. Furthermore, it is observed that the converter and filter design play major role in synchronization of PV with grid. Developing sufficient control techniques for grid-connected inverter equipped with LCL filter is a complex task. The grid integrated PV system is explored through simulations conducted in MATLAB/Simulink, where an initial network model is developed for the PV power system. This paper suggests that the low value of the power factor may lead to heavy damage due to the high current flow in loads and these simulation results are presented as per power factors extemporizations.

    A static synchronous compensator (STATCOM) is a powerful mechanism for balancing reactive power and uplift voltage stability in a transmission system. Nowadays, the desire to save energy by reducing losses is prioritized as an essential target instead of increasing the power generation for the sustainability of any nation’s growth plans. As a result, power-electronics-based converters are more significant for power savings in transmission systems. STATCOM based on voltage source converters (VSC) are operated to improve on stable performance conditions as well as to minimize the harmonic distortions in a power system. Hence, this paper explores low harmonic distortions of fifteen-level VSC structured STACOM using only one DC-link voltage to balance the reactive power and to manage the voltage profile in large power transmission systems. STATCOM consisting of H-bridge type VSCs and binary weighted transformers was utilized to maintain an AC system voltage at 132 kV, 50 Hz. The three stages of VSCs were operated with meticulous firing angles based on converter levels for controlling THD (total harmonic distortion) and providing system improvement. The proposed model of the fifteen-level H-bridge type voltage source converters with fuzzy logic decoupled control algorithm based STATCOM can be used for large power range applications with a small number of switches. This model attained stable operation of the system with a low harmonic deviation at any dynamical conditions. The simulation results using MATLAB showed that the system’s operation was enhanced, with a smoother response and improved steady state performance.
