2. 1. Stability of Low-Frequency AC Railways : Models and Transient Stability

   Author : John Laury; Lars Abrahamsson; Math Bollen; Pablo Arboleya; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

   Abstract : Low-frequency AC railway grids are unique in the sense that a only few countries around the world uses them, still however, they are an important parts of their countries infrastructures. Due to the usage of a dierent frequency than the public grid of the country, conversion of frequency is needed for the interconnection. READ MORE

4. 2. Wind Turbine Models for Power System Stability Studies

   Author : Abram Perdana; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fixed-speed; variable-speed; validation; modelling; power system stability; frequency stability; aggregated model; wind turbine; voltage stability;

   Abstract : The purpose of this thesis is to develop dynamic models of wind turbines for power system stability studies. More specifically, the wind turbine models are mainly intended for voltage and frequency stability studies. READ MORE

5. 3. Analysis and Design of Hybrid Systems

   Author : Stefan Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

   Abstract : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. READ MORE
