摘要:

为了有效地降低综合能源系统(integrated energy system, IES)碳排放量,解决退役动力电池梯次利用中存在的安全问题,提出了退役动力电池应用于IES的低碳经济调度方法。首先,提出基于置信区间估计的退役动力电池重构储能系统(reconfiguration energy storage system, RESS)可靠性评估方法,并设置合理的充放电安全阈值,提高退役动力电池运行的安全性;其次,追踪退役动力电池的碳耗特性,建立退役动力电池梯次利用于IES全过程的碳排放成本模型;最后,引入阶梯式碳交易模式,建立IES碳排放成本及运行成本模型,并考虑分时电价阶段性地调节梯次利用电池的安全阈值实现IES低碳经济调度。通过多场景仿真分析验证了退役动力电池梯次利用于IES的调度方法能有效降低系统的碳排放和成本。

Abstract:

To effectively reduce carbon emissions of the integrated energy system (IES) and solve safety problems in the echelon utilization of retired power batteries, this study proposes a low-carbon economic dispatch method for the application of retired power batteries in IES. First, a reliability evaluation method based on confidence interval estimation for retired power battery reconfiguration energy storage system (RESS) is proposed. A reasonable charge and discharge safety threshold improves the operation safety of retired power batteries. Second, the carbon consumption characteristics of retired power batteries are tracked. In addition, the carbon emission cost model for the retired power batteries in the whole process of echelon utilization to IES is established. Finally, the stepped carbon trading model is introduced, and the IES carbon emission cost and operating cost model is established. The battery safety threshold of the echelon utilization is periodically adjusted by considering the time-of-use electricity price, which realizes economical low-carbon dispatch of the IES. Through multi-scenario simulation analysis, the scheduling method for echelon utilization of retired power batteries in IES can effectively reduce the carbon emissions and costs of the verified system.

Key words: retired power battery, integrated energy system, confidence interval estimation, safety threshold, low-carbon economic dispatch
