Abstract

The increasing demand for high-efficiency power conversion in grid-connected systems has driven the development of advanced converter architectures. This paper proposes a novel grid-integrated power enhancement framework based on an 11-level cascaded H-bridge converter integrated with a Solid-State Transformer (SST)-aware -aware multi-level converter. The system is designed to address critical challenges, including voltage regulation, harmonic suppression, power factor correction, and dynamic stability, in high-power applications. A hybrid metaheuristic optimization strategy combining the Golden Eagle Optimizer (GEO) and Firefly Algorithm (FA) is employed to fine-tune the converter parameters for improved efficiency, reduced power losses, and optimal control response. A Proportional-Integral-Derivative Double Derivative (PIDD2) controller is incorporated to ensure robust load balancing and transient stability under varying load conditions. MATLAB/Simulink-based simulations validate the proposed system’s effectiveness in maintaining low Total Harmonic Distortion (THD), improved power factor, and enhanced voltage quality, demonstrating its suitability for modern grid-interfaced power conversion systems.
