This paper presents a modular, simulation-driven control framework for grid-connected hybrid photovoltaic-wind systems. The framework organises conventional PI-based loops in a hierarchical structure with power, DC-link voltage and dq-current layers, and augments them with a mode-switching decision-logic module capable of transitioning between passive (load-following) and active (grid-support) operation in real time. Implemented entirely in MATLAB/Simulink, the framework includes automated disturbance emulation and a script-based benchmarking workflow that allows fair comparison between the proposed Simulation-Driven Hierarchical Mode-Switching Control (SDHMC) and reference PI, MPC, SMC and FLC controllers under identical plant and scenario settings. For the studied hybrid PV-wind case, SDHMC reduces settling time by about 58% and lowers current THD by around 53% compared to a conventional PI design, while maintaining DC-link voltage deviations within +/- 1.2% during severe grid-voltage sags. The contribution is thus a reusable high-fidelity simulation benchmark and control architecture at converter level; experimental and hardware-in-the-loop validation are identified as essential next steps.eninfo:eu-repo/semantics/openAccessautomated controlgrid integrationmodel-based simulationrenewable energy systemssmart grid optimizationstability and power qualityArticle10.1002/ese3.704142-s2.0-105025529861Q1WOS:001642343000001Q3
