  2. 1. Power System Damping - Structural Aspects of Controlling Active Power

    Author : Olof Samuelsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. READ MORE

  4. 2. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

    Author : Björn Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power systems; bang-bang control; shading tolerance; power quality; photovoltaic; embedded generation; current control; solar power generation;

    Abstract : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. READ MORE
