This paper presents a system-level modeling and simulation study of the 22 kV distribution network of Boujdour, southern Morocco, integrating photovoltaic (PV) and wind energy. The PV and wind models are validated using real operational SCADA data. Two operating conditions are analyzed: grid-connected operation with PV injection and a main-grid-loss condition with combined PV–wind generation. The results show how renewable intermittency affects power balance and medium-voltage voltage behavior and identify infrastructure constraints that limit further renewable penetration. The study provides a validated operational baseline for future smart-grid extensions involving dynamic inverter models, energy storage, advanced monitoring, and data-driven forecasting.
