2. 1. Availability Analysis of Three Different Types of Combined Cycle Power Plants

   Author : Javed S. Alvi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCC power plants; NOx reduction; IGCC power plants; Makrov process; repair policies; effectiveness; PFBC power plants; active redundancy; backup fuel reducition;

   Abstract : The goal of power plants with higher efficiency and lower environmental risk than conventional power plants has produced three types of combined cycle power plants. These are: 1) the conventional combined cycle (CCC) power plant, 2) the pressurised fluidised bed combustion (PFBC) power plants, and 3) the integrated gasification combined cycle (IGCC) power plants.

4. 2. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

   Author : Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

5. 3. Grid-forming wind power plants

   Author : Anant Narula; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

6. 4. Disruptive power : How distributed energy resources shape organizations and value logics in the future of electricity systems

   Author : Martin Warneryd; Eva Thorin; Ewa Wäckelgård; Dick Magnusson; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : The electricity sector faces its largest transformation since its beginning about a century ago. Combinations of ageing electricity networks, removal of fossil supply sources and electrification of industry and transport sectors require vast efforts at all levels of society. READ MORE

7. 5. Wind Power Integration in Power Systems with Transmission Bottlenecks

   Author : Julija Matevosyan; Lennart Söder; Olav Bjarte Fosso; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; hydro power; transmission bottlenecks; stochastic optimization; Electric power engineering; Elkraftteknik;

   Abstract : During the last two decades, the increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. READ MORE
