储能已被确定为创新的优先技术。然而，在目前的监管制度下，迅速发展的储能技术系列将难以与传统发电机竞争提供电力系统服务，这可能会阻碍创新。本文分析了阻碍储能技术在电力市场中短期应用的16个投资障碍，其中最重要的是目前将储能列为发电资产的监管障碍，尽管它不能提供正的净电力流量，这被用来证明双重网络使用费的合理性。平衡和辅助市场的优序设计阻碍了存储技术收回其相对较高的资本成本的能力，而容量市场则惩罚了其有限的放电持续时间。网络公司处于实现存储系统价值的最佳位置，但它们的所有权只有在系统操作独立于网络操作的情况下才能被接受。目前解决这些问题的举措包括灵活的连接协议和开发增强的频率响应和聚合快速储备服务。然而，为了消除已确定的障碍，需要建立一个重视存储所提供的灵活性的市场结构，将其视为网络和发电资产的补充而不是竞争。
Energy storage has been identified as a priority technology for innovation. However, the rapidly developing family of storage technologies will find it difficult, under the current regulatory regimes, to compete with conventional generators for the provision of electricity system services, and this is likely to impede innovation. This paper analyses and categorizes 16 investment barriers hindering the near-term deployment of energy storage technologies in electricity markets, which are related to four regulatory and public attitudes barriers.The most important regulatory barrier is the current classification of storage as a generation asset, despite it being unable to provide a positive net flow of electricity, which is used to justify double network usage charges. The merit order design of balancing and ancillary markets hampers the ability of storage technologies to recoup their relatively high capital cost, while capacity markets penalize their limited discharge duration. Network companies are in the best position to realize the system value of storage, but their ownership may only be acceptable if system operation is made independent of network operation.Current initiatives to address these issues include flexible connection agreements and the development of enhanced frequency response and aggregate fast reserve services. However, to remove the identified barriers, a market structure that valued the flexibility offered by storage, viewing it as complementing rather than competing with network and generation assets, would be required.
