Hybrid ac–dc reconfigurable link technology can find interesting applications in medium-voltage power distribution. These are networks having dc links operating in parallel alongside ac links with post-fault reconfiguration capability. A given system can operate in different configurations while maintaining equivalent capacity during (n−1) contingencies using reconfigurability. This paper provides a method for the ideal selection of the link configuration by defining the efficiency and economic viability boundaries with varying operating power demand and power factor. A sensitivity analysis with parameters such as grid voltage, link length, conductor area, and converter efficiency as well as economic factors such as converter cost and link conductor installation cost is discussed. The study identifies the operating zones wherein the refurbished parallel ac–dc reconfigurable distribution links can be an efficient and economically preferred option of delivering power as compared to a system with only ac or dc links.

配电网中翻新并联 AC-DC 可重构链路的运行边界

混合交流-直流可重构链路技术可以在中压配电中找到有趣的应用。这些网络具有直流链路与具有故障后重新配置能力的交流链路并行运行。给定的系统可以在不同的配置下运行，同时使用可重构性在 (n-1) 次突发事件期间保持等效容量。本文通过定义具有不同运行功率需求和功率因数的效率和经济可行性边界，为链路配置的理想选择提供了一种方法。讨论了对电网电压、链路长度、导体面积和转换器效率等参数以及转换器成本和链路导体安装成本等经济因素的敏感性分析。
