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

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

   Sammanfattning : 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. LÄS MER

3. 2. Modeling, Control and Protection of Low-Voltage DC Microgrids

   Författare :Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

   Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER

4. 3. Electric Power Generation and Storage Using a High Voltage Approach

   Författare :Björn Bolund; Mats Leijon; Hans Bernhoff; Tore Undeland; Uppsala universitet; []
   Nyckelord :Engineering physics; Flywheel; Generation; Generator; High Voltage; Power flow; Poynting; Teknisk fysik;

   Sammanfattning : Production and consumption of electricity have grown enormously during the last century. No mater what the primary source of energy is, almost all generation of electricity comes from conversion of a rotational movement in a generator. The aim of this thesis is to see how high voltage technology influence production and storage of electricity. LÄS MER
