The optimal configuration of energy storage capacity is an important issue for large scale solar systems. a strategy for optimal allocation of energy storage is proposed in this paper. First various scenarios and their value of energy storage in PV applications are discussed. Then a double-layer decision architecture is proposed in this article.
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 precondition for the effectiveness of the control strategy is to ensure that the energy storage is equipped with sufficient capacity to avoid the inability to track the target power. However, a larger energy storage capacity is not always better, considering economic factors.
Therefore, capacity allocation of the energy storage is required to balance the requirements of both aspects. For capacity allocation, the capacity of energy storage equipment determines its ability to effectively stabilize wind power fluctuations.
Comparison of capacity allocation. Table 3 shows that the total cost of energy storage is increased by 5.40 % when considering effective capacity attenuation. Since the allocation of the supercapacitor basically remains the same, the capacity attenuation mainly affects the capacity allocation results of the battery.
Additionally, from the standpoint of capacity allocation, the battery's service life can be reasonably estimated according to its life attenuation mechanism, and the energy storage capacity allocation that meets the wind power smoothing requirements can be achieved in combination with the economic cost analysis.
