Capacity Configuration of Energy Storage Systems for Echelon Utilization Based on Accelerated Life Test in Microgrids
Retired power battery construction energy storage systems (ESSs) for echelon utilization can not only extend the remaining capacity value of the battery
and decrease environmental pollution
but also reduce the initial cost of energy storage systems. In this paper
an ESS constructed of retired power batteries for echelon utilization in microgrids (MGs) is considered. Firstly
considering the influence of different discharge depths on the battery life cycle
the correlation equation between the state of charge (SOC) and the state of health (SOH) is established. Secondly
the accelerated life test method
based on the inverse power law coefficient equation
is proposed
and it is used to evaluate the reliability of the ESS. Finally
according to the SOC characteristics
the dynamic security margin of the ESS is established. The life cycle cost
supply-demand balance and ESS balanced control are comprehensively considered
and the location and capacity of energy storage in MGs are determined. It is simulated using the IEEE-RTS 24 node system; the results show that the investment cost of the ESS is reduced and the operational life is prolonged.
