An Advanced Protection Scheme for Enabling an LVDC Last Mile Distribution Network

Protecting the last mile – enabling an LVDC distribution network

Traditional distribution power systems are facing numbers of changes. The major aspects that may influence the shape of the changes include: the connection of small scale renewable and advanced distributed energy resources, the deployment of demand side controls, and the supply of more heat and transport demands. But, because distribution systems have been designed and operated with very limite...

Evaluation of Existing DC Protection Solutions on an Active LVDC Distribution Network under Different Fault Conditions

Low Voltage Direct Current (LVDC) distribution is considered as one of the new promising technologies for better integration of distributed generation, and supplying local loads in more efficient way compare to AC systems. However, DC protection is still considered as one of the outstanding challenges that holds back the wide deployment of LVDC in last mile utility applications. Most of existin...

Last Mile Distribution in Humanitarian Relief

Last mile distribution is the final stage of a humanitarian relief chain; it refers to delivery of relief supplies from local distribution centers (LDCs) to beneficiaries affected by disasters. In this study, we consider a vehicle-based last mile distribution system, in which an LDC stores and distributes emergency relief supplies to a number of demand locations. The main decisions are allocati...

An Online Free Penetration Multi-Stage Fuse Saving Protection Scheme in Distribution Systems with Photovoltaic Sources

In this paper, a multi-stage protective scheme is proposed to maintain the fuse and reclosers coordination. The proposed method operates online and proportional to the photovoltaic sources penetration rate. In the first step, a non-standard Current - Time - Voltage curve is used for fuse saving. If the new calculated TDS from the first stage is not implementable to the reclosers, the second sta...
