Description of Technical and Research Challenge:Different concepts of power electronic converters (PEC) for distribution networks have been proposed and tested in demonstration projects in the UK. Notably, the soft open point (SOP) converter and different forms of fault current limiter devices have been shown to help mitigating network constraints arising from the growth of distributed generation and EV chargers. Still, trials have also shown that the controllers in these devices are not ready for a large scale deployment: spurious tripping due to myriad of circumstances and faulty communication links forces technicians to visit the installation frequently to identify the problem and rearm the device. Further, it is unclear how neighbouring devices with voltage regulation or line-balancing roles would play together (e.g. would some form of recirculation occur if two devices applied opposing corrective actions?).Novelty and Objectives of PhD Project:Rather than demonstrating the benefits of these converters, which has been the focus of prior research in this area, this project would focus on the operational logic of power electronic converters acting as SOPs and other types of power electronic converters for distribution networks. The project will look at the mechanisms that can be put in place for the SOP to identify faults (ie both network faults and hardware faults) and act accordingly; it will also consider the effect of these converters in the protection settings of the network to identify potential incompatibilities and come up with a proposal for what these converters should do when short-circuits happen.

技术和研究挑战的描述：在英国的示范项目中，已经提出并测试了用于配电网的电力电子转换器（PEC）的不同概念。值得注意的是，软开路点（SOP）转换器和不同形式的故障电流限制器器件已被证明有助于缓解分布式发电和电动汽车充电器增长带来的网络限制。尽管如此，试验也表明，这些设备中的控制器还没有准备好进行大规模部署：由于各种情况和通信链路故障而导致的虚假跳闸迫使技术人员频繁访问安装以识别问题并重新装备设备。此外，尚不清楚具有电压调节或线路平衡作用的相邻设备将如何一起发挥作用（例如，如果两个设备应用相反的纠正措施，是否会发生某种形式的再循环？）。博士项目的新奇和目标：而不是证明这些转换器的好处，这一直是在这一领域的研究重点，这个项目将集中在电力电子转换器的操作逻辑作为SOP和其他类型的电力电子转换器的配电网。该项目将研究SOP可用于识别故障（即网络故障和硬件故障）并采取相应行动的机制;它还将考虑这些转换器在网络保护设置中的影响，以识别潜在的不兼容性，并提出短路发生时这些转换器应该做什么的建议。
