Can energy storage systems improve performance in solar power shared building communities?
Analyze detailed energy sharing processes in a Swedish building community. Proper energy storage system design is important for performance improvements in solar power shared building communities. Existing studies have developed various design methods for sizing the distributed batteries and shared batteries.
Why do buildings need a solar PV system?
To mitigate the large carbon emissions in the building sector, increasing solar photovoltaic (PV) are installed in buildings, due to its easy scalability, installation and relatively low maintenance. The Swedish Energy Agency set a target that building installed PV systems contribute 5–10% of the total electricity generation by 2040 .
Can a battery store PV power?
The battery of the second system can store power from photovoltaic (PV) panels as well as power from the grid at low valley electricity prices. In particular, the stored power can be supplied to the buildings and sold to the grid.
How does surplus sharing reduce the battery needs of buildings?
In Scenarios 2&3, the surplus sharing reduces the battery needs of buildings for keeping the surplus power inside the community. Due to a lack of solar irradiation in winter, the surplus sharing is very limited. Fig. 10.
