Proof of Concept project to prove supporting technologies for Ultra-large Composite Flywheel deployment in Energy Storage

该项目重点关注英国对储能解决方案日益增长的需求，以支持可再生能源部署和电网整合，并减少TSB能源供应战略2012中概述的高峰时期国家电网的压力-“通过储能开发支持可再生能源部署，以满足具有法律约束力的温室气体减排目标”。提出的解决方案是开发更大的复合飞轮，产生兆瓦时，而不是用现有的解决方案产生千瓦时。关键目标是证明大型复合材料飞轮储能的技术、成本可行性和效益。通过与潜在终端用户的讨论，商业产品需要以下目标/应用：低电压穿越不敏感，VArmanagement，存储效率，旋转储备，黑启动，快速响应，快速固定和小占地。该项目的创新之处在于证明原位制造工艺的概念，该工艺能够制造具有粘结质量和夹杂物尺寸的复合材料飞轮，以支持环向和径向应力的要求。进一步的创新是开发一个磁轴承的安排，支持在一个受挫的圆锥中心转子和补偿运行期间的径向增长。该系统将在真空中运行，利用Halbach阵列来支撑飞轮的重量，以实现无摩擦运行。项目的主要好处是证明了车间的概念创新和完成基本材料强度试验，以验证理论设计工作和制造过程。这使EPL能够制定开发路线图，以进一步开发与关键材料和系统合作伙伴一起构建初始原型飞轮的技术。如果成功，该项目有助于解决英国和国外的能源存储问题，支持可再生能源系统的部署，加强当地电网的使用和稳定性。

This project focuses on the UKs growing need for energy storage solutions to supportrenewable energy deployments & grid integration & to reduce strain on the national gridduring peak times as outlined in the TSB’s Energy Supply Strategy 2012 – “supportingrenewable energy deployments through energy storage developments to meet legally bindingtargets for greenhouse gas reduction”. The proposed solution is to develop much largerComposite Flywheels producing MWh’s rather than kWh’s with existing solutions. Keyobjectives are to prove the technical & cost feasibility & benefits of large composite flywheelenergy storage. Through discussions with potential end-users, the commercial productrequires the following objectives/applications: Low Voltage Ride Through insensitive, VArmanagement, storage efficiency, spinning reserve, Black Start, rapid response with fastramping & small footprint.Project innovation is to prove the concept of an in-situ manufacturing process capable ofbuilding composite flywheels with the quality of bond & inclusion size to support thedemands of hoop & radial stress. Further innovation is to develop a magnetic bearingarrangement supported on a frustrated cone to centre the rotor & compensate for radial growthduring operation. The system will run in a vacuum utilising Halbach arrays to support theflywheel weight for friction free running.Key project benefits are to prove the concept innovations in the workshop & to completebasic material strength trials to validate the theoretical design work & manufacturing process.This enables EPL to develop an exploitation roadmap to further develop the technology tobuild an initial prototype flywheel in conjunction with key material & systems partners. Ifsuccessful, the project contributes to the longer term goal of resolving energy storage issues inthe UK & abroad & supports the deployment of renewable energy systems & strengtheninglocal grid usage & stability.
