What is it about?

This article examines how residential photovoltaic (PV) self-consumption, with and without battery storage, can support the integration of renewables in low-voltage distribution networks. Using real data from a Portuguese neighborhood, the study compares different configurations and assesses their impact on voltage profiles, grid losses, and hosting capacity for distributed generation. The findings show that self-consumption and storage reduce grid stress and can improve the ability to integrate more PV generation without costly infrastructure upgrades.

Why is it important?

As renewable energy sources grow, local grids face challenges related to voltage control and overproduction. This study provides evidence that promoting self-consumption and battery use at the residential level can ease these issues. It’s an important contribution for utilities, regulators, and policymakers aiming to balance clean energy goals with reliable grid operation. The work also supports the design of incentives for prosumers to invest in technologies that benefit both their household and the overall electrical network.

Perspectives

This study aligns with my broader research interest in enabling the transition to more sustainable and decentralized energy systems. It highlights the dual role of residential PV systems—not only as a means for energy independence but also as a resource to enhance grid performance. Combining real data analysis with technical simulations allowed us to present solutions that are both practical and scalable for future energy planning.
