Joint optimisation of arbitrage profits and battery life degradation for grid storage application of battery electric vehicles

摘要: To meet European decarbonisation targets by 2050, the electrification of transport sector is mandatory. Most electric vehicles rely on lithium-ion batteries, because they have a higher energy/power density and longer life span compared to other practical batteries such as zinc-carbon batteries. Electric can thus provide energy storage support system integration generation from highly variable renewable sources, wind photovoltaics (PV). However, charging/discharging causes degradate progressively with reduced capacity. In this study, we investigate impact joint optimisation arbitrage revenue battery degradation vehicle in simplified setting, where historical prices allow for market participation owners. It shown that both leads stronger gains then sum strategies including into model avoids state charges close maximum at times. be concluded an important aspect consider power models, which incorporate any kind storage.
