Integration of Energy Storage Systems and Modern Flexible AC Transmission Devices

在大容量电力传输系统中，基于电力电子器件的使用可以潜在地克服目前机械控制传输系统的局限性。它们可以帮助推迟或减少建设更多输电线路的需要，并使邻近的公用事业和地区能够经济可靠地交换电力。现有的柔性交流输电系统（FACTS）技术对有功潮流相关的系统性能影响有限。将储能系统（ESS），如电池储能、超导磁能储能、飞轮储能或超级电容器储能集成到FACTS设备中，可以提供动态分散的有功功率能力和急需的灵活性，以减轻传输级潮流问题。这项工作将侧重于FACTS/ESS集成的电力电子和控制拓扑设计。将研究现有的电力电子和控制拓扑结构。将提出集成柔性交流传输系统（FACTS）和储能系统（ESS）设备的创新设计。拟议的项目将由两所大学，弗吉尼亚理工大学和um -罗拉大学，以及BWX技术公司和桑迪亚国家实验室组成的合作伙伴计划进行。储能与电力电子设备的集成在不同规模上有许多其他应用，包括航空母舰和海军舰艇，电动和混合动力汽车，电敏感制造和远程能源使用，如气象研究站，岛屿系统和军事应用，如地面防御系统。

In bulk power transmission systems, the use of power electronics based devices can potentially overcome limitations of the present mechanically controlled transmission system. They can help delay or minimize the need to build more transmission lines and enable neighboring utilities and regions to economically and reliably exchange power. The existing Flexible AC Transmission System (FACTS) technologies have limited impact on active power flow related system performance. Integrating an energy storage system (ESS), such as battery energy storage, superconducting magnetic energy storage, flywheel energy storage, or super capacitor energy storage, into a FACTS device can provide dynamic decentralized active power capabilities and much needed flexibility for mitigating transmission level power flow problems.This work will focus on power electronics and control topologies design for FACTS/ESS integration. Existing power electronics and control topologies will be researched. Innovative design will be proposed for integrating flexible AC transmission systems (FACTS) and energy storage systems (ESS) devices. The proposed project will be conducted between a partnership program composed of two universities, Virginia Tech and UM-Rolla, along with BWX Technologies, Inc. and Sandia National Laboratory.The integration of energy storage with power electronics devices has many other applications in different scales including aircraft carrier and naval shipboard, electric and hybrid-electric vehicles, electrically sensitive manufacturing and remote energy usage such as weather research stations, island systems, and military applications such as ground based defense systems.
