This paper explores the use of Digital Twin (DT) technology for real-time health monitoring of grid-integrated photovoltaic (PV) systems. The proposed DT is developed through conceptualization, computational modeling, and experimental validation, functioning as a mathematical replica of the hardware system. Operating alongside the physical setup, the DT leverages measured sensor data to enable accurate tracking and control. A novel Power Law Charge Function-based Enhanced Adaptive Artificial Electric Field Optimization (EAAEFO) algorithm is employed to continuously compare DT outputs with real system measurements, ensuring precise analysis. For control, a Unit Vector Integrated Sliding Mode Control (UVISMC) scheme based on Cascaded Generalized Integrator (CGI) is introduced. This strategy provides improved current tracking, robustness, and reduced sensitivity to parameter variations compared to conventional controllers. The DT framework is implemented on the OPAL-RT (OP4512) platform, while the hardware prototype operates on an NI sbRIO-9636 FPGA board using LabVIEW. Health degradation of interfacing inductors, converter switches, and DC-link capacitors is examined by analyzing its impact on system performance. Experimental validation demonstrates that the DT achieves over 98% accuracy in replicating hardware behavior, even under degraded conditions, establishing its effectiveness for PV system monitoring and control.

The integration of hybrid AC/DC transmission lines introduces significant challenges in power system protection. Harmonic-rich secondary arc currents (SAC) prolong extinction time, leading to relay malfunctions and auto-reclosing failures. This study proposes a genetic optimization framework for secondary arc harmonics (SAH) mitigation, employing an online design technique through synchronized PSCAD-MATLAB simulations based on the Nondominated Sorting Genetic Algorithm II (NSGA-II). Optimized passive filters are designed for both baseline (AC/AC) and hybrid configurations. Results demonstrate that hybrid systems achieve superior SAH suppression with reduced filter requirements, highlighting their economic advantage over conventional lines. Experimental protection relay tests validate the proposed approach, confirming its effectiveness in enhancing system protection.
