1. Fault location in resonant earthed medium voltage distribution systems
Sammanfattning : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

3. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment
Sammanfattning : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. LÄS MER
4. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking
Sammanfattning : This Ph.D. thesis investigates the possibility of using energy storage systems for multiple services by implementing service stacking, with special emphasis on congestion management in distribution grids. LÄS MER
5. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning
Sammanfattning : The importance of electricity in everyday life and demands to improve the reliability of distribution systems force utilities to operate and plan their networks in a more secure and economical manner. With higher demands on reliability from both customers and regulators, a big pressure has been put on the security of electricity supply which is considered as a fundamental requirement for modern societies.
