This dataset contains the research data (grid topology, component parameters, and time-series load/generation data) of the journal article https://doi.org/10.1080/14786451.2026.2618349: Abstract: Rural grids in Morocco face increasing energy demand and infrastructure limitations, necessitating sustainable solutions to ensure reliable electricity supply. This study investigates the impact of integrating photovoltaic (PV) systems and energy storage on grid reinforcement requirements in a rural medium-voltage grid in Morocco, considering an annual energy demand increase of at least 5\%. Based on a current grid in 2023, future grid scenarios for 2030 and 2040 were simulated using the open-source Python library pandapower to assess grid performance under different expansion strategies. These scenarios include (1) load growth without PV and storage integration, (2) PV integration alone, and (3) combined PV and energy storage solutions. The findings indicate that integrating PV and storage reduces the need for traditional grid reinforcements and improves voltage stability. In particular, storage integration significantly decreases transformer loading and mitigates line congestion, highlighting its role in voltage stabilization. By reducing dependence on fossil fuel-based generation and increasing local energy self-sufficiency, these solutions contribute to Morocco’s renewable energy transition. The study emphasizes the need for strategic investments in distributed energy resources to enhance the sustainability and reliability of rural electricity grids.
