2. 1. Interruptible Load Services in Deregulated Power Market

   Author : Anh Tuan Le; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion management; deregulated electricity market; ancillary services; optimal power flow; reserve generation; interruptible load management;

   Abstract : Since the nineties decade, many electric utilities world-wide have been under restructuring from vertically integrated functioning to deregulated open-market system. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole.

4. 2. Interruptible Load as an Ancillary Service in Deregulated Electricity Markets

   Author : Anh Tuan Le; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reserve generation; least-cost planning.; interruptible load management; optimal power flow; ancillary services; deregulated electricity market; congestion management;

   Abstract : Power companies world-wide have been restructuring their electric power systems from a vertically integrated entity to a deregulated, open-market environment. Previously, electric utilities usually sought to maximize the social welfare of the system with distributional equity as its main operational criterion. READ MORE

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. Risk-Averse Planning, Operation, and Coordination of Energy Systems Considering Uncertainty Modeling and Flexibility Services

   Author : Hamed Bakhtiari; Jin Zhong; Manuel Alvarez; Jalal Kazempour; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system planning and operation; energy systems coordination; uncertainty modeling; microgrids; renewable energy; Electric Power Engineering; Elkraftteknik;

   Abstract : Uncertainty sources affect the planning and operation of energy systems. Different system operators need proper alternatives to cope with these uncertainties and improve the operation of their systems from technical and economical viewpoints. READ MORE

7. 5. Modeling and Simulations of Demand Response in Sweden

   Author : Daniel A. Brodén; Lars Nordström; Mikael Amelin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand response; demand side management; model predictive scheduling; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Electric power systems are undergoing a paradigm shift where an increasing number of variable renewable energy resources such as wind and solar power are being introduced to all levels of existing power grids. At the same time consumers are gaining a more active role where self energy production and home automation solutions are no longer uncommon. READ MORE
