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.
Since the allocation of the supercapacitor basically remains the same, the capacity attenuation mainly affects the capacity allocation results of the battery. For the optimization results of the battery, the rated capacity is increased by 6.09 %, the rated power is increased by 3.63 %, and the lifetime is decreased by 2.52 %.
Therefore, adjusting the output power of energy storage reasonably can effectively reduce the degradation cost of the battery, thereby lowering the overall operating costs of the microgrid. The same applies to agricultural and pastoral areas. Figure 12. Battery output power and degradation cost.
