"Hybrid AC\/DC CIGRE LV Digital Twin with HHO & PSO Optimized VSC Setpoints"

"This dataset contains the complete Digital Twin and optimization framework used in the study \u201cModeling and Validation of a Hybrid AC\/DC Grid Using a Digital Twin and Metaheuristic Optimization\u201d. A PyDAE-based model of the CIGRE European Low-Voltage benchmark grid is implemented, extended by an 800 V DC overlay interfaced through eight Voltage Source Converters (VSCs). The dataset further includes penalty-constrained Harris Hawks Optimization (HHO) and Particle Swarm Optimization (PSO) algorithms used to compute optimal VSC setpoints that ensure per-phase current limits and grid voltage compliance. The final setpoints were validated across four representative load scenarios, enabling decentralized operation without real-time communication. Files include simulation codes, VSC control results, load profiles, figures, and performance evaluation results necessary for full reproducibility."
