  1. 6. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

    Författare :Johan Setréus; Lina Bertling; Roland Eriksson; Stefan Arnborg; Lars Wredenberg; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 7. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

    Författare :Björn Lindgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power systems; bang-bang control; shading tolerance; power quality; photovoltaic; embedded generation; current control; solar power generation;

    Sammanfattning : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. LÄS MER

  4. 8. Planning Models for Single Wire Earth Return Power Distribution Networks

    Författare :Geofrey Bakkabulindi; Lennart Söder; Mikael Amelin; Peiyuan Chen; KTH; []
    Nyckelord :Rural electrification; power distribution planning; Single Wire Earth Return; distribution power flow; power system modeling; SRA - Energy; SRA - Energi;

    Sammanfattning : The high cost of grid extension to rural areas, often characterized by scattered communities with low load densities, requires the use of low cost electrification technologies to ensure economic viability. In Single Wire Earth Return (SWER) power distribution networks, the earth itself forms the current return path of the single phase system leading to significant cost savings on conductors, poles and poletop hardware compared to conventional systems.

  5. 9. Exploring the future low-carbon electricity system: impacts of nuclear power and demand patterns

    Författare :Xiaoming Kan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; net system cost; electricity supply mix; Low-carbon electricity system; variable renewable energy; nuclear power; electricity system cost; demand pattern; energy system modeling;

    Sammanfattning : To achieve the climate goals set by the Paris Agreement, the global electricity system is expected to transition towards a low-carbon electricity system. The future low-carbon electricity system is uncertain regarding both generation and demand. LÄS MER

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

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

    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.
