Learn MoreA study conducted in Ref. shows that a basic energy sharing among 21 residential buildings in Sweden, i.e. aggregate the electricity demand and supply of all the buildings, can easily improve the PV power self-consumption by over 15%.
Photovoltaic with battery energy storage systems in the single building and the energy sharing community are reviewed. Optimization methods, objectives and constraints are analyzed. Advantages, weaknesses, and system adaptability are discussed. Challenges and future research directions are discussed.
Therefore, this study proposes a hierarchical design method of distributed batteries in solar power shared building communities, with the purpose of reducing the battery capacity and minimizing the energy loss in the sharing process.
The system with the battery regulates the mismatch between electricity load and PV generation by storing surplus PV power and discharging battery to meet the remaining electricity demand, which can achieve the goal of making full use of renewable energy and availably reducing PV rejection rate, , .
In this study, the energy sharing within a solar powered building community is further classified into two types: surplus sharing (i.e. use the surplus PV power to meet the electricity needs in other buildings) and storage sharing (i.e. store or take electricity from other buildings' batteries).
Operation logic of battery and energy sharing in the proposed hierarchical design. The hierarchical design will minimize the aggregated storage sharing (i.e. aggregated E b a t, o t h e r, i) and thus maximize the usage of the buildings' own batteries (i.e. aggregated E b a t, o w n, i).
