Integration of Energy Storage Systems and Modern Flexible AC Transmission Devices

在大容量电力传输系统中，使用基于电力电子的装置可以潜在地克服当前机械控制的传输系统的限制。 它们可以帮助延迟或最大限度地减少建造更多输电线路的需求，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的影响有限。 将储能系统（ESS），如电池储能、超导磁储能、飞轮储能、超级电容储能等集成到FACTS装置中，可以提供动态分散的有功功率容量和灵活性，以缓解输电层的潮流问题，本文将重点研究FACTS/ESS集成的电力电子和控制拓扑设计。 现有的电力电子和控制拓扑结构将进行研究。 将提出集成灵活交流输电系统（FACTS）和储能系统（ESS）设备的创新设计。 拟议的项目将在由弗吉尼亚理工大学和UM-Rolla两所大学组成的合作计划与BWX技术公司沿着进行。能量存储与电力电子器件的集成具有不同规模的许多其他应用，包括航空母舰和海军船上、电动和混合电动车辆、电敏感制造和远程能量使用（例如天气研究站、岛屿系统）以及军事应用（例如地基防御系统）。

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.
