本文概述了在配电系统中使用中压直流（MVDC）（5-50 kV）元件作为加速低碳技术部署的一种手段的情况。该方法使用现有的电缆和架空资产，最初设计到交流系统的安全目的。通过选择性地转换为直流电，可以创建一个内部GSP（电网供电点）平衡网络，只需在变电站进行修改。这种方法允许增加网络传输能力，而不会像传统互连那样增加故障级别。从现实世界的苏格兰郊区配电网络的数据，这种方法的好处和障碍进行了检查。现有网络的功率流基准下的各种现在和未来的负载情况。可控的MVDC链路被引入到网络和潮流研究，用于评估这种方法的网络加固的价值。使用工业试验数据预测了这种方案的成本估计。
This paper outlines the case for using Medium Voltage Direct Current (MVDC) (5–50 kV) elements in distribution systems as a means to accelerate the deployment of low carbon technologies. The approach uses existing cable and overhead assets, originally designed into the ac system for security purposes. By selective conversion to dc, an inter GSP (grid supply point) balancing network can be created with modifications only required at substations. This approach allows for increased network transfer capability without increasing fault level as would be the case with conventional interconnection. Using data from a real-world Scottish suburban distribution network, the benefits and barriers to such an approach are examined. Power flows for the existing network are benchmarked under various present day and future loading scenarios. Controllable MVDC links are introduced to the network and power flow studies used to assess the value of such an approach to network reinforcement. Cost estimates for such a scheme are projected using data from industrial trials.
