Reliable electricity supply forms a one of the basic requirements of modern 21st Century life. Sustaining this reliable supply is one of the key challenges for the coming decades. A solution is not straight-forward and will have many parts. Integrating offshore wind energy generation as cheaply as possible is one part. Linking our electricity transmission network to the generation and services of other European countries is another part. Reinforcing the onshore electricity network to cope with new power flows, is a further part. Addressing these challenges requires an offshore electricity network, which is controlled to support our existing infrastructure. Such an offshore network disrupts far less of the onshore countryside and living environment than conventional onshore solutions. Enabling this necessary offshore network is the goal of this proposal. The technology needed to achieve such a solution is so-called Voltage-Source High-Voltage DC Transmission (VSC-HVDC): DC connections using converter stations with the latest state-of-the-art, high-voltage semiconductor power processing technology. Only such stations have the required flexibility, compactness offshore and ability to transmit power over long sub-sea cables. However our experience with such technology is limited to point-to-point systems. No small networks (so-called multi-terminal systems) have been built. No large networks (so-called DC grids) have been constructed. Very little research has been published into how to control such systems. There is a dearth of information on how to make large offshore networks 'work'. However many industrial and academic organizations have highlighted the substantial potential benefits in terms of reduced cost, improved reliability and greater functionality which could be offered by such DC offshore networks to our existing electricity infrastructure. This project will undertake the research urgently required to assess the best way to control and mange such networks. Since telecommunications, controller architecture and control are intimately linked, research to assess and include the impact of these constraints will also be incorporated. Candidate networks will be formulated, analyzed and simulated using state-of-the-art models. These models will be improved to include the effects of distributed control and telecommunications effects/Quality of Service. New techniques will be developed that allow similar benefits to 'perfect' (idealized Master) control to be achieved with more realistic distributed hardware systems.The transformative goals of this project are thus:1. To establish how Master and Distributed Master controllers can improve VSC-HVDC-grid performance and offer robust and reliable services to AC onshore networks.2. To investigate advanced controls, and effective exploitation of state-of-the-art and developing telecommunication technologies, to integrate this control with local station control and to overcome conventional operational speed limitations.Better system understanding, models, and improved control will result. This in turn should allow the creation of a cheaper, more effective offshore network.

可靠的电力供应构成了现代21世纪生活的基本要求之一。维持这种可靠的供应是未来几十年的主要挑战之一。解决方案不是直率的，并且会有很多部分。尽可能便宜地整合海上风能是一部分。将我们的电力传输网络与其他欧洲国家的一代和服务联系起来是另一部分。加强陆上电网络以应对新的电力流，这是另一部分。应对这些挑战需要一个海上电力网络，该网络被控制以支持我们现有的基础架构。这样的海上网络比传统的陆上解决方案少了陆上乡村和生活环境的破坏。实现此必要的海上网络是该提案的目标。实现此类解决方案所需的技术是所谓的电压源高压直流传输（VSC-HVDC）：使用转换器与最新最先进的高压半导体电源处理技术的DC连接。只有这样的电台才具有所需的灵活性，紧凑性和在长次海电缆上传输电源的能力。但是，我们在这种技术方面的经验仅限于点对点系统。没有建立任何小型网络（所谓的多终端系统）。尚未构建大型网络（所谓的直流网格）。关于如何控制此类系统的研究很少。关于如何使大型离岸网络“工作”缺乏信息。然而，许多工业和学术组织都在降低成本，可靠性和更大的功能方面强调了潜在的巨大收益，这些DC离岸网络可以为我们现有的电力基础设施提供。该项目将迫切需要进行研究，以评估控制和管理此类网络的最佳方法。由于电信，控制器架构和控制密切相关，因此还将纳入评估和包括这些约束影响的研究。将使用最新模型制定，分析和模拟候选网络。这些模型将得到改进，以包括分布式控制和电信效果/服务质量的影响。将开发新技术，通过使用更现实的分布式硬件系统实现“完美”（理想化的主）控制的类似好处。该项目的变革性目标是：1。为了建立主体和分布式主控制器如何改善VSC-HVDC-GRID性能，并为AC Onshore网络提供强大而可靠的服务2。调查高级控制，并有效利用最先进的电信技术，以将该控制与本地站的控制并克服常规的操作速度限制。贝特系统的理解，模型和改进的控制将产生。反过来，这应该允许建立更便宜，更有效的海上网络。
