Finding a reasonable capacity configuration of the energy storage equipment is fundamental to the safe, reliable, and economic operation of the integrated system, since it essentially determines the inherent nature of the integrated system .
In the uppermost capacity configuration level, the capacities of energy storage equipment are optimized considering the investment costs and the feedback of operating performance of the entire plant. The candidate capacity is sent to the operation optimization stage as reference device capacities.
In this paper, the optimal allocation strategy of energy storage capacity in the grid-connected microgrid is studied, and the two-layer decision model is established. The decision variables of the outer programming model are the power and capacity of the energy storage.
The last result of energy storage configuration is calculated through the probability of each scene. Renewable energy is volatile and intermittent, therefore to stabilize its energy consumption through the energy storage technology is necessary.
To reflect the residual energy of the battery, the SOC is denoted by: (4) SOC t = SOC t − Δt + Δ E bat t E n _ bat where En_bat is the rated capacity of the battery. Battery life degradation is a gradual and cumulative process. This paper assumes that the SOC estimates are accurate.
In this paper, a optimal configuration method of energy storage in grid-connected microgrid is proposed. Firstly, the two-layer decision model to allocate the capacity of storage is established. The decision variables in outer programming model are the capacity and power of the storage system.

Cell Capacity and Pack Size
Changing to a 5Ah cell you now need 20 of these connected in parallel to equal the capacity of two of the 50Ah cells connected in paralel. Hence, as shown a 96s30p pack configuration gives a total pack energy of 34.6kWh. However, now we see that the step down to 19p or up to 21p changes the total energy of the pack by 96 x 3.6V x 5Ah = 1.728kWh
