  1. 1. Managing Service Levels in Grid Computing Systems : Quota Policy and Computational Market Approaches

    Författare :Thomas Sandholm; Lennart Johnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grid Market; Computational Grid; Service Level Management; QoS; HPC; Grid Middleware; Computer science; Datavetenskap;

    Sammanfattning : We study techniques to enforce and provision differentiated service levels in Computational Grid systems. The Grid offers simplified provisioning of peak-capacity for applications with computational requirements beyond local machines and clusters, by sharing resources across organizational boundaries.

  3. 2. Sustainability of rural energy access in developing countries

    Författare :Brijesh Mainali; Semida Silveira; Benjamin Sovacool; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Access; Rural electrification; Rural energy; Household; Renewable energy; Off-grid; Mini-grid; Grid; Pathways; Fuel choice; Indicator; Sustainability index; Energy Technology; Energiteknik;

    Sammanfattning : The importance of access to modern energy has been well understood by governments and donor agencies in many developing countries, and significant effort has been made in recent years to address energy access challenges. However, despite these efforts, the International Energy Agency (IEA) has predicted that the energy access problem will remain unresolved by 2030. LÄS MER

  4. 3. Renewable Energy Market for Rural Electrification in Developing Countries: Country Case Nepal

    Författare :Brijesh Mainali; Semida Silveira; Björn Kjellström; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; renewable energy; rural electrification; off-grid; financing; subsidy; credit; equity; market; extensive growth; intensive growth; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The availability of abundant renewable resources, lack of fossil fuels and difficult geographical terrain for grid line extensions contribute to the advantages of renewable based decentralized rural electrification in Ne-pal. Solar home system (SHS) and micro-hydro are the most commonly adopted off-grid renewable energy technologies in the country. LÄS MER

  5. 4. Improved Self-Consumption of Photovoltaic Electricity in Buildings : Storage, Curtailment and Grid Simulations

    Författare :Rasmus Luthander; Joakim Widén; Joakim Munkhammar; Ewa Wäckelgård; Nicholas Etherden; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Self-consumption; Grid integration; Distributed generation; Energy storage; Curtailment; Power system; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.

  7. 5. Grid-forming wind power plants

    Författare :Anant Narula; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power plants WPPs ; grid-forming GFM ; inertia; Ancillary services; frequency support; coordination; current limitation; energy storage systems ESS ; transient stability;

    Sammanfattning : With growing concerns over climate change, the power system is witnessing an unprecedented growth in electricity generation from intermittent renewable energy sources (RES) such as wind and solar, which are commonly interfaced to the grid by power-electronic converters. However, increasing the penetration level of converter-interfaced generation units reduces the number of synchronous generators (SGs) in the grid that provide system services to support voltage and frequency, either inherently or through mandatory requirements and market products.
