What is distributed grouping shared energy storage design?

The proposed distributed grouping shared energy storage design is able to reduce the optimal total battery capacity and the total annual cost compared to the other two energy storage designs.

Does community building grouping improve battery capacity?

Based on the results of the community building grouping, a new battery capacity optimization method is proposed. The proposed distributed group-shared design is compared with the existing distributed non-grouping design and distributed group design to analyze the impact on battery capacity and system economics of the three designs.

What is the optimal battery capacity compared to a distributed non-Grouping design?

Compared to the distributed non-grouping design (Scheme 1), the optimal total battery capacity and total annual cost can be reduced by 20.7 % and 16.1 %, respectively. Compared to the distributed grouping design (Scheme 2), the optimal total battery capacity and total annual cost can be reduced by 5.1 % and 1.5 %, respectively.

What is a distributed non-grouping battery?

The distributed non-grouping design requires the maximum optimal total battery capacity, which is 2102.03 kWh, and also the maximum total annual cost and power purchased from the grid, which is 700,139.11 CNY and 1,478,714.90 kWh, respectively.

Why is the installation of energy storage system important?

The installation of the energy storage system (ESS) is an important way to handle the uncertainty of PV power generation and load [, , , ], which can effectively improve the stability and operational efficiency of the power system in the community.

Why is energy shared between buildings after grouping?

It can be observed that very little energy is shared between the groups after grouping, which is due to the fact that the sharing potential between buildings is fully stimulated by dividing the buildings that generate excess renewable energy and those that cannot meet the electricity demand into one group.
