Lasse Kappel Mortensen attended the Conference on Power, Energy, and Electrical Engineering (CPEEE) in Tokyo, Japan, and won the award for best presentation

From the 25th to the 27th of February 2023, Lasse Kappel Mortensen attended the Conference on Power, Energy, and Electrical Engineering (CPEEE) in Tokyo, Japan, where he presented the paper “Binary search for three-phase fault location in low voltage distribution systems using smart meters’ last gasp functionality”.

For his presentation, Lasse Kappel Mortensen won the ‘Best presentation award’.

The paper proposes a method to locate faults in low-voltage grids using communication among agents in a radio-mesh smart meter communication network. The method is tested using a multi-agent-based digital twin developed in connection with a previous research article. The digital twin creates the framework for a risk-free test and development environment. The new fault-finding method should be compared with current practices for outage management in low-voltage networks, where typical solutions are the existing ‘last gasp’ functionality which in practice can only be used to detect faults and not find them due to small emergency power systems (capacitors) and collisions in radio network communication. In addition, many DSOs depend on calls from disconnected consumers as well as fieldwork to find faults in the low-voltage network. The proposed method has, in all tests, been able to find all affected consumers within a time frame of 2 to 5 minutes.

The research has been conducted as part of the EUDP ’Smart fault prediction and location in distribution grids’ project.
