2. 1. Analyzing Substation Automation System Reliability using Probabilistic Relational Models and Enterprise Architecture

   Author : Johan König; Lars Nordström; Sebastian Lehnhoff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability analysis; substation automation; Enterprise Architecture; probabilistic analysis; Probabilistic Relational Models; Bayesian networks; software reliability; failure rates; fault tree analysis;

   Abstract : Modern society is unquestionably heavily reliant on supply of electricity. Hence, the power system is one of the important infrastructures for future growth. READ MORE

4. 2. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

   Author : Johan Setréus; Lina Bertling; Roland Eriksson; Stefan Arnborg; Lars Wredenberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; Electric power engineering; Elkraftteknik;

   Abstract : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. READ MORE

5. 3. Identifying critical components for system reliability in power transmission systems

   Author : Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission system reliability; component reliability importance index; Great Britain power system; power flow analysis; system adequacy; system security; system vulnerability;

   Abstract : Large interruptions of power supply in the transmission system have considerable impact on modern society. The goal for the transmission system operator (TSO) is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. READ MORE

6. 4. Thermal Study of a Submerged Substation for Wave Power

   Author : Antoine Baudoin; Cecilia Boström; Didier Saury; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; marine substation; heat transfer; natural convection; CFD; FEM; thermal management;

   Abstract : At the Division of Electricity of Uppsala University, a wave power concept is being developed.It relies on wave energy converters, one buoy and one linear generator placed on the seabed, connected together to a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

7. 5. Reliability Evaluation of Distribution ArchitecturesConsidering Failure Modes and Correlated Events

   Author : Sajeesh Babu; Patrik Hilber; Hans Kristian Høidalen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Power systems are in a phase of automation where intelligent components and sub-systems are employed to monitor, control and manage the grid. Quantifying the complex consequences on system reliability, from the integration of such automated and semi-automated equipment into the existing grid is important for maintenance optimisation and fault mitigation.
