2. 16. The impact of wind power variability on the least-cost dispatch of units in the electricity generation system

   Author : Lisa Göransson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; intermittency; wind-thermal system; variability; cycling costs; electricity generation system; dispatch modeling; variation management;

   Abstract : This thesis investigates the dynamics of electricity generation systems that involve high levels of wind power. Methods to account for wind power variability in electricity-dispatch models are explored, and the impact of wind power variability on the optimal output of the generation units, so as to meet the system load with the lowest possible cost (economic dispatch), is analyzed for several systems, for both regional and European cases.

4. 17. Distributed Photovoltaics, Household Electricity Use and Electric Vehicle Charging : Mathematical Modeling and Case Studies

   Author : Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Photovoltaics; Household Electricity Use; Electric Vehicle Charging; Markov Chain Modeling; Probability Distribution Modeling; Data Analysis; Self-Consumption; Grid Interaction.; Engineering Science; Teknisk fysik;

   Abstract : Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. READ MORE

5. 18. Electrification of Road Transportation - Implications for the Electricity System

   Author : Maria Taljegård; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

   Abstract : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.

6. 19. Road user charging for heavy goods vehicles - Implementation aspects

   Author : Eva Schelin; Peter Värbrand; Clas Rydergren; Lena Trojer; Eric Sampson; Linköpings universitet; []
   Keywords : road user charging; heavy goods vehicles; distance based; marginal cost principle; implementation model; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Several factors have influenced the recent development in charging of heavy goods vehicles in Europe. European legislation is changed and the political will is strong in many countries. The public awareness and acceptance is large for the need to put a price and a cost on the use of infrastructure. READ MORE

7. 20. Impact on the Distribution System due to Plug-In Electric Vehicles and Changes in Electricity Usage

   Author : David Steen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in hybrid electric vehicle PHEV ; Electric vehicle EV ; Plug-in Electric Vehicle PEV ; Open loop radial distribution system; Electrical distribution system; Load management;

   Abstract : Replacing conventional vehicles by Plug-in Electric Vehicles (PEVs) would likely increase electricity demand and put higher stress on the electrical power system. This thesis presents an approach to evaluate the impact on electrical distribution systems (DSs) caused by charging PEVs and load management of heating loads. READ MORE
