摘要:

电池储能有望在能源系统的低碳转型中发挥至关重要的作用。然而,在电网中部署电池存储目前受到其低经济可行性的严重限制,这不仅是由于高资本成本,而且还缺乏灵活有效的利用方案和商业模式。通过卡车运输使公用事业规模的电池存储变得便携,从而释放了其提供各种按需服务的能力。我们介绍了公用事业规模的便携式储能的潜在应用,并调查其在加利福尼亚州的经济性,使用时空决策模型,确定最佳的操作和运输计划的便携式存储。我们发现,动员储能可以在某些地区将其生命周期收入增加70%,并通过缓解当地输电拥堵来改善可再生能源整合。时空套利的生命周期收入可以完全补偿加州几个地区的便携式储能系统的成本,包括圣地亚哥和旧金山湾区。

英文摘要:

Battery storage is expected to play a crucial role in the low-carbon transformation of energy systems. The deployment of battery storage in the power gird, however, is currently severely limited by its low economic viability, which results from not only high capital costs but also the lack of flexible and efficient utilization schemes and business models. Making utility-scale battery storage portable through trucking unlocks its capability to provide various on-demand services. We introduce the potential applications of utility-scale portable energy storage and investigate its economics in California using a spatiotemporal decision model that determines the optimal operation and transportation schedules of portable storage. We show that mobilizing energy storage can increase its life-cycle revenues by 70% in some areas and improve renewable energy integration by relieving local transmission congestion. The life-cycle revenue of spatiotemporal arbitrage can fully compensate for the costs of portable energy storage system in several regions in California, including San Diego and the San Francisco Bay Area.
