摘要

储能系统(ESS)是解决可再生能源大规模部署所带来的问题的一项有前途的技术。部署ESS是一项业务决策,需要对潜在收入进行评估。目前的价值评估方法主要针对储能业主或电力公司。需要充分考虑ESS的系统价值,以在整个电力系统中获得广泛的利益理解。因此,本文提出了一种基于改进的考虑输电损耗的直流潮流模型的并网ESS系统价值评估方法,以量化系统总价值避免成本。选择节约生产成本、延迟升级、环境效益和节约传输损耗四种典型应用来代表ESS在整个电力系统中的系统价值。此外,基于中国电力市场规律,提出了考虑“源-网-储”协同运行和电池容量退化的协同优化模型,用于调峰调频。该方法在仿真和实验研究中得到了验证。

System value assessment method of energy storage system for multi-services of power system considering battery degradation

The energy storage system (ESS) is a promising technology to address issues caused by the large-scale deployment of renewable energy. Deploying ESS is a business decision that requires potential revenue assessment. Current value assessment methods focus on the energy storage owner or the electricity utility. The system value of the ESS needs to be fully considered to gain a broad understanding of benefits across the whole power system. Thus, this study proposes a system value assessment method of grid-integrated ESS to quantify the total system value-avoided cost based on an improved DC power flow model considering transmission losses. Four typical applications (production cost saving, upgrade deferral, environmental benefit, and transmission loss saving) are chosen to represent the system value of the ESS across the whole power system. In addition, the co-optimisation model considering the “source-grid-storage” coordination operation and battery capacity degradation, is proposed for peak shaving and frequency regulation based on the Chinese power market rule. The proposed method is tested in simulation and experimental studies.
