2. 1. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

   Author : David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

   Abstract : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. READ MORE

4. 2. Solar Variability Assessment and Grid Integration : Methodology Development and Case Studies

   Author : David Lingfors; Joakim Widén; Uwe Zimmermann; Eva Wäckelgård; Tobias Boström; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar variability; Photovoltaics; Grid integration; GIS; Distributed generation; Engineering Science; Teknisk fysik;

   Abstract : During the 21st century there has been a tremendous increase in grid-connected photovoltaic (PV) capacity globally, due to falling prices and introduction of economic incentives. PV systems are in most cases small-scale, installed on residential dwellings, which means that the power production is widely distributed and close to the end-user of electricity. READ MORE

5. 3. Millimetre wave waveguide enclosed grid frequency multipliers and imaging

   Author : Robin Dahlbäck; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave; THz imaging; THz sources; Grid; Heterostructure Barrier Var- actors HBVs ; Varactors; Array; FMCW; 2D-grid; Quasi-optical.; Frequency multipliers; Radars; sub-millimetre waves; Schottky diodes;

   Abstract : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. READ MORE

6. 4. Wind Turbine Characterization by Voltage Source Converter Based Test Equipment

   Author : Nicolas Espinoza; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grid Integration; Frequency Scan; Discrete Control; Wind Power; Grid Emulation; Voltage Source Converter VSC ; Grid Code; Low Voltage Ride Through LVRT ;

   Abstract : In countries where wind power has become a relevant part of the total generated electrical power, transmission system operators (TSOs) have included in their Grid Codes specific technical requirements for interconnection of wind power plants. Some Grid Codes demand specific testing procedures in order to verify the fulfilment for their requirements. READ MORE

7. 5. Improved Self-Consumption of Photovoltaic Electricity in Buildings : Storage, Curtailment and Grid Simulations

   Author : Rasmus Luthander; Joakim Widén; Joakim Munkhammar; Ewa Wäckelgård; Nicholas Etherden; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Self-consumption; Grid integration; Distributed generation; Energy storage; Curtailment; Power system; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Abstract : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.
