Effect in the aggregated demand of solar-plus-storage prosumers in the residential sector

Solar photovoltaics (PV) are one of the low-carbon technologies to address climate change. Residential PV and battery energy storage are expected to increase significantly in the near future. This increase will likely be driven by falling prices, government incentives and a growing awareness of climate change. This study explores the evolution of the electricity demand patterns occurring from a mass deployment of solar PV systems and battery storage in the residential sector. Multiple scenarios are investigated concerning the penetration rate of PV only and PV-plus-storage systems, as well as, the typology and operation of the battery energy storage systems. The results can help evaluate planning and operational constraints in power networks regarding solar energy integration and the system's net demand. System operators can benefit from this study and its methodology as a decision-making tool for their planning activities to accommodate higher levels of renewable energy in the power grids of the future.
