Microgrids for uninterruptable power supply systems (UPS) have been used in high-value service provider buildings for many years. Despite they use conventional network topologies with relatively conventional control and protection systems, the use of low voltage DC to supply information technologies (IT) loads is rapidly becoming standard. In these systems, DC is is seen as an opportunity to improve reliability and to reduce energy losses and costs. Today the market of photovoltaics, batteries, power electronics and IT hardware keeps growing as these technologies become more cost-competitive. Thus, the use of DC could be extended to further types of loads, generation and storage giving rise to hybrid AC-DC microgrids. When considering the current business-as-usual approach to electrical network design, planning and operation, the growth of renewables and power electronics is often seen as a threat to electrical networks. However, by exploiting the controllability of power electronics it would be possible to build highly-reliable, energy-efficient and cost-effective networks with low carbon impact. High-value buildings today present interesting opportunities to test new concepts of microgrids that could be used at a larger scale in the future. However, multiple technical questions still remain unanswered, such as: "how much can microgrid design be optimised while preserving high reliability?" or "how does low level control for transient stability affect battery life span and how can it be improved?" to name a few. This project seeks to answer these questions by bringing together world leading expertise on microgrids, network planning, energy storage, power converter design and power electronic control from the UK and Korea. The project will consider hybrid AC-DC microgrids with loads, generation and energy storage connected in either side. It will focus on applications to high-value service provider buildings with the ambition of generating knowledge that will be useful in other applications and at greater distribution network scale.

用于不间断电源系统（UPS）的微电网已在高价值服务提供商建筑中使用多年。尽管它们使用传统的网络拓扑结构和相对传统的控制和保护系统，但使用低压直流供电信息技术（IT）负载正迅速成为标准。在这些系统中，直流被视为提高可靠性和减少能源损失和成本的机会。今天，光伏、电池、电力电子和IT硬件市场不断增长，因为这些技术变得更具成本竞争力。因此，直流的使用可以扩展到其他类型的负载、发电和存储，从而产生交直流混合微电网。当考虑到目前电网设计、规划和运营的常规方法时，可再生能源和电力电子的增长通常被视为对电网的威胁。然而，通过利用电力电子的可控性，有可能建立高可靠性、高能效和低成本的低碳影响网络。今天的高价值建筑提供了有趣的机会来测试微电网的新概念，这些概念可以在未来更大规模地使用。然而，许多技术问题仍然没有得到解决，例如：“微电网设计在保持高可靠性的同时可以优化多少？”或“低电平控制对暂态稳定性的影响以及如何改进？”该项目旨在通过汇集英国和韩国在微电网、网络规划、能源存储、电源转换器设计和电力电子控制方面的世界领先专业知识来回答这些问题。该项目将考虑将负载、发电和储能连接在两侧的交直流混合微电网。它将专注于高价值服务提供商建筑的应用程序，其目标是产生在其他应用程序和更大的分销网络规模中有用的知识。
