由于化石燃料资源的使用减少，未来的电力系统预计将集成大规模的随机和间歇性发电和负荷，包括可再生能源和电动汽车（EV）。包括这些资源对同步输电和配电网络的动态稳定性提出了挑战，尤其是在发电方面，系统惯性可能不完全由大规模发电控制，而是由小规模和局部发电取代。储能系统（ESS）可以通过提供支持储备来限制分散和分布式发电的影响，同时适应大规模EV连接;后者（负载）也参与存储供应。在这项研究中，提出了一种本地能量存储系统（LESS）。讨论了LESS的结构、要求和最佳尺寸。详细介绍了三种操作模式，包括：（i）存储包管理;（ii）正常操作;和（iii）应急操作。拟议的LESS计划进行评估，使用模拟研究的基础上获得的数据从北方爱尔兰区域和住宅网络。
Future power systems are expected to integrate large‐scale stochastic and intermittent generation and load due to reduced use of fossil fuel resources, including renewable energy sources and electric vehicles (EV). Inclusion of such resources poses challenges for the dynamic stability of synchronous transmission and distribution networks, not least in terms of generation where system inertia may not be wholly governed by large‐scale generation but displaced by small‐scale and localised generation. Energy storage systems (ESS) can limit the impact of dispersed and distributed generation by offering supporting reserve while accommodating large‐scale EV connection; the latter (load) also participating in storage provision. In this study, a local energy storage system (LESS) is proposed. The structure, requirement and optimal sizing of the LESS are discussed. Three operating modes are detailed, including: (i) storage pack management; (ii) normal operation; and (iii) contingency operation. The proposed LESS scheme is evaluated using simulation studies based on data obtained from the Northern Ireland regional and residential network.
