2. 1. Steady state analysis of HVDC grid in the North Sea with offshore wind power plants

   Author : Kalid Yunus; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduled exchange power; NPV; transmission fee tariff; primary controller; ARIMA; external AC grid connection; secondary supervisory controller; meshed HVDC transmission grid; VSC HVDC; WPP;

   Abstract : In this thesis, some of economical and technical aspects of expanding the HVDC (High Voltage Direct Current) transmission systems in the North Sea are studied at steady state. In the thesis, it is assumed that the expansion of the system is made by connecting WPPs (Wind Power Plants) to the system which is built for power exchange. READ MORE

4. 2. Steady state analysis of HVDC grid with Wind Power Plants

   Author : Kalid Yunus; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ARIMA; electricity price; meshed HVDC grid; WPP; transmission tariff; temporal and spatial correlation; electricity market; VSC HVDC; wind speed modelling; secondary supervisory controller; LRMC; SRMC; PV; primary controller; investment cost;

   Abstract : The idea of building a multi-terminal, even a meshed HVDC grid in the North Sea, that can inter-connect surrounding nations, is being discussed widely. Such a system is expected to be realised in steps through the interconnection of wind power plants and electricity markets. READ MORE

5. 3. On Harmonic Emission, Propagation and Aggregation in Wind Power Plants

   Author : Kai Yang; Roberto Langella; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

   Abstract : The increasing use of wind energy is a global trend as part of the overall transition to a more sustainable energy system. By using modern technologies, the wind energy is converted into electric power which is transported to the consumers by means of the electric power system. READ MORE

6. 4. 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.

7. 5. Between Strategic Political Power and a Daunting Task : Exploring Dimensions of Women’s Political Participation in Hybrid Regimes

   Author : Anna Ehrhart; Gustav Lidén; Susanne Wallman Lundåsen; Zeynep Kadirbeyoglu; Josefina Erikson; Mittuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : Hybrid regimes combine elements of both democratic and authoritarian governance, with potentially flawed democratic processes, suppressed civil liberties and uneven political playing fields. Increasingly, scholarship signals the longevity and resilience of hybrid regimes, especially within broader discourses on rising authoritarianism and democratic decline around the world. READ MORE
