Frequency response from a Liquid Air Energy Storage LAES plant Abstract Highview Power Storage is a UK based developer of energy storage systems which use liquid air as the energy storage medium. Liquid Air Energy Storage LAES systems, demonstrated for many years at pilot scale, will offer a bulk energy storage option that will add resilience and flexibility to the power network of the UK and to export markets around the world. LAES plants are built using established technology, sourced from a global mature supply chain, commonly found in the industrial gas and LNG sectors. A Pre Commercial Partial Demonstrator has been built at Pilsworth in Greater Manchester and is currently being commissioned. This system has received 8m pounds in funding from DECC and the funds sought from Innovate UK for this proposed project will have additionality by converting the partial demonstrator into the worlds first ever commercial scale full LAES system with rapid response capability. LAES systems function by using an electrically driven compressor based refrigeration system to condense air into a cryogenic fluid. The liquid air LAIR is stored in low pressure tanks until the system is required to discharge, at which point ambient or waste heat is applied and work is captured from the expanding gas in an expansion turbo generator note that the generator is typically synchronous and as a result, naturally provides inertia to the system. Highview have developed a way to enhance the design of LAES systems in order to provide rapid enhanced frequency response services with future LAES plants. This project will explore a first of a kind deployment of their newly patented system innovations and ascertain the commercial benefit of entering future National Grid Enhanced Frequency Response tenders, in addition to the demand for similar services and faster response times in general around the world.

液体空气储能LAES工厂的频率响应摘要Highview Power Storage是一家英国的储能系统开发商，该系统使用液体空气作为储能介质。液态空气储能LAES系统已在试点规模上展示多年，将提供一种散装储能选择，为英国电网和全球出口市场增加弹性和灵活性。LAES工厂使用成熟的技术建造，来自全球成熟的供应链，通常在工业气体和液化天然气领域。在大曼彻斯特的Pilsworth建造了一个预商用部分演示器，目前正在调试中。该系统已从DECC获得800万英镑的资金，而从Innovate UK寻求的资金将通过将部分演示器转换为世界上第一个具有快速响应能力的商业规模完整LAES系统来获得额外资金。LAES系统通过使用基于电驱动压缩机的制冷系统来将空气冷凝成低温流体而起作用。液态空气LAIR存储在低压罐中，直到系统需要排放，此时施加环境或废热，并且从膨胀涡轮发电机中的膨胀气体捕获功。注意，发电机通常是同步的，因此，自然地为系统提供惯性。Highview开发了一种方法来增强LAES系统的设计，以便为未来的LAES工厂提供快速增强的频率响应服务。该项目将探索其新专利系统创新的首次部署，并确定进入未来国家电网增强频率响应招标的商业利益，以及全球对类似服务和更快响应时间的需求。
