  1. 1. Identifying critical components for system reliability in power transmission systems

    Author : Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  2. 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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  3. 3. Reliability in performance-based regulation

    Author : Torbjörn Solver; Lennart Söder; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance-Based Regulation; Distribution System; Power System Reliability; Monte Carlo Simulations; Quality of Supply; Electric power engineering; Elkraftteknik;

    Abstract : In reregulated and restructured electricity markets the production and retail of electricity is conducted on competitive markets, the transmission and distribution on the other hand can be considered as natural monopolies. The financial regulation of Distribution System Operators (DSOs) has in many countries, partly as a consequence of the restructuring in ownership, gone through a major switch in regulatory policy.

  4. 4. On reliability and maintenance modelling of ageing equipment in electric power systems

    Author : Tommie Lindquist; Roland Eriksson; Lina Bertling; George Anders; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability; maintenance; electric power systems; circuit breaker; disconnector; thermography; Electric power engineering; Elkraftteknik;

    Abstract : Maintenance optimisation is essential to achieve cost-efficiency, availability and reliability of supply in electric power systems. The process of maintenance optimisation requires information about the costs of preventive and corrective maintenance, as well as the costs of failures borne by both electricity suppliers and customers.

  5. 5. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning

    Author : Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; George Anders; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

    Abstract : 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.
