Development of Models and Control Schemes for Soft Open Points in Distribution Systems

More than 80% of power outages in power grids are caused by faults in distribution networks. To improve the system’s reliability and resiliency, the service restoration is critical after faults. The Soft Open Point (SOP) is an emerging power electronic device, which can be connected to terminals of feeders or between networked microgrids, and can be used to realize service restoration. In this proposal, we aim to develop models and control schemes of SOPs in distribution systems for service restoration purpose. To achieve effective service restoration, models and control schemes of SOPs must be developed under both normal and faulty operating conditions. Compared to traditional network reconfigurations, service restoration through SOPs is more secure and reliable, and can significantly enhance the faulty system’s self-healing capability in distribution networks. The research results will greatly benefit the power grid modernization for Saskatoon Light & Power’s future urban distribution network.
