Appropriate allocation of energy storage equipment in microgrids is an effective means to deal with the uncertainty of renewable energy generation. Allocating a reasonable amount of energy storage capacity to a microgrid can improve its operational economy and power supply reliability [7, 8].

First, a microgrid, including electric vehicles, is constructed.
The fluctuation of renewable energy resources and the uncertainty of demand-side loads affect the accuracy of the configuration of energy storage (ES) in microgrids. High peak-to-valley differences on the load side also affect the stable operation of the microgrid.
A novel formulation for the battery energy storage (BES) sizing of a microgrid considering the BES service life and capacity degradation is proposed. The BES service life is decomposed to cycle life and float life. The optimal BES depth of discharge considering the cycle life and performance of the BES is determined.
The simulation results show that the optimal configuration of ES capacity and DR promotes renewable energy consumption and achieves peak shaving and valley filling, which reduces the total daily cost of the microgrid by 22%. Meanwhile, the DR model proposed in this paper has the best optimization results compared with a single type of the DR model.

Nowadays, microgrids (MGs) have received significant attention. In a cost-effective MG, battery energy storage (BES) plays an important role. One of the most important challenges in the MGs is the optimal sizing of the BES that can lead to the MG better performance, more flexible, effective, and efficient than traditional power systems.
