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.
The simulation results show that, for the battery life model considering the effective capacity attenuation, its life estimation value is reduced by 2.52 %, and the battery's allocation capacity is increased by 6.09 %.
Therefore, more effective capacity is required to ensure the capacity redundancy. Secondly, the capacity attenuation of the battery leads to an increased discharge depth in its later operating periods, resulting in an increase in the accumulated equivalent discharge, so the life decays faster. 4.2.2.
