The implementation of peak shaving strategies in a microgrid significantly affects the lifetime of energy storage systems (ESS) by influencing their cycling frequency, depth of discharge, and operating temperature. Peak shaving involves using the ESS to reduce the peak demand from the grid or other generation sources, typically by discharging the ESS during periods of high demand and charging it during periods of low demand. The impact on the ESS lifetime depends on several factors: Cycling Frequency: Peak shaving strategies generally increase the cycling frequency of the ESS, as it is charged and discharged more frequently compared to other applications, such as backup power. The cycle life of a battery, which is the number of charge-discharge cycles it can withstand before its capacity degrades to a certain level (typically 80%), is a key indicator of its lifespan. Increased cycling frequency reduces the cycle life of the ESS. Depth of Discharge (DoD): The depth of discharge, which is the percentage of the battery's capacity that is discharged during each cycle, also affects the ESS lifetime. Deeper discharges generally reduce the cycle life of the battery. Peak shaving strategies often i....
