Aging-Aware Multi-Service Optimization of Heterogeneous Second-Life EV Battery Energy Storage Systems

Abstract

This paper evaluates the multi-service operation of a heterogeneous second-life battery energy storage system (ESS) participating in the day-ahead electricity market and frequency containment reserves (FCR-N, FCR-D Up, FCR-D Down). A rolling horizon mixed integer linear programming (MILP) is developed to co-optimize market revenues, power schedule, and degradation, using linearized calendar and cycle aging models derived from BLAST simulations. The 20-pack second-life ESS (0.978 MWh, 0.874 MW) is formed by duplicating ten distinct EV battery types to reflect realistic repurposing scenarios. Simulation results show strong economic performance, achieving €319,109 in annual profit, dominated by FCR-D Up, FCR-D Down, and FCR-N capacity... (More)

This paper evaluates the multi-service operation of a heterogeneous second-life battery energy storage system (ESS) participating in the day-ahead electricity market and frequency containment reserves (FCR-N, FCR-D Up, FCR-D Down). A rolling horizon mixed integer linear programming (MILP) is developed to co-optimize market revenues, power schedule, and degradation, using linearized calendar and cycle aging models derived from BLAST simulations. The 20-pack second-life ESS (0.978 MWh, 0.874 MW) is formed by duplicating ten distinct EV battery types to reflect realistic repurposing scenarios. Simulation results show strong economic performance, achieving €319,109 in annual profit, dominated by FCR-D Up, FCR-D Down, and FCR-N capacity revenues, while degradation costs remain low (€14,454). Power dispatching patterns reveal that high-power chemistries absorb most regulation events, whereas high-energy chemistries provide long-duration buffering and maintain stable SoE. The results demonstrate that properly optimized heterogeneous second-life batteries can deliver profitable and reliable multi-service grid support with controlled aging.
