To enhance the utilization of renewable energy and the economic efficiency of energy system''s planning and operation, this study proposes a hybrid optimization configuration method for battery/pumped hydro energy storage considering battery-lifespan attenuation in the regionally integrated energy system (RIES).
Capacity attenuation refers to the gradual loss of a lithium-ion battery''s ability to store and deliver energy. Typically, this manifests as a decline in State of Health (SOH) and a reduced runtime for the device or vehicle. Understanding why this happens is critical for improving battery performance and extending lifespan.
If Attenuation is expressed as Voltage, the attenuation the formula becomes: A (Voltage) = 20 log10 ( V s / V d ) V s = voltage at source. V d = voltage at destination. Attenuation is often expressed in dBs per foot, meter, kilometre etc. The lower the attenuation figure over any given measurement of distance, the more efficient the cable is.

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.
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.
To enhance the utilization of renewable energy and the economic efficiency of energy system's planning and operation, this study proposes a hybrid optimization configuration method for battery/pumped hydro energy storage considering battery-lifespan attenuation in the regionally integrated energy system (RIES).
Therefore, if the battery operates without considering lifespan attenuation, the cost of replacing the battery beyond the project period must be considered, thereby resulting in a considerably high overall system cost.
