  1. 1. Impact of dependencies in risk assessments of power distribution systems

    Författare :Karin Alvehag; Lennart Söder; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning :  Society has become increasingly dependent on electricity, so power system reliability is of crucial importance. However, while underinvestment leads to an unacceptable number of power outages, overinvestment will result in costs that are too high for society. The challenge is to find a socioeconomically adequate level of risk. LÄS MER

  2. 2. Risk-based methods for reliability investments in electric power distribution systems

    Författare :Karin Alvehag; Lennart Söder; Kjølle Gerd; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distribution system reliability; risk management; quality regulation design; customer interruption costs; weather modeling; Monte Carlo simulations; Electric power engineering; Elkraftteknik;

    Sammanfattning : Society relies more and more on a continuous supply of electricity. However, while underinvestments in reliability lead to an unacceptable number of power interruptions, overinvestments result in too high costs for society. LÄS MER

  3. 3. Electricity Distribution Network Planning Considering Distributed Generation

    Författare :Yalin Huang; Lennart Söder; Karin Alvehag; Peiyuan Chen; KTH; []
    Nyckelord :Electricity distribution network; network planning; distributed generation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution.

  4. 4. Impact of Economic Regulation on Distributed Generation Integration in Electricity Distribution Grids

    Författare :Angela Picciariello; Lennart Söder; Karin Alvehag; Gert Brunekreeft; KTH; []
    Nyckelord :Distributed generation; distribution economic regulation; regulatory impact; distribution tariff design; cost allocation methodologies; cross subsidies; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Energy policies in favor of a larger adoption of renewable energy sources for electricity production purposes and the significant progress of several renewable technologies are among the main drivers behind an increasing integration of distributed generation (DG) in distribution networks.DG affects distribution network planning and operation and, consequently, higher or lower network costs than in a traditional passive network scenario arise.
