1. 1. Modeling and forecasting the load in the future electricity grid : Spatial electric vehicle load modeling and residential load forecasting

   Författare :Mahmoud Shepero; Joakim Munkhammar; David Steen; Uppsala universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Electric Vehicles; GIS; Photovoltaics; Residential Load Forecasting;

   Sammanfattning : The energy system is being transitioned to increase sustainability. This transition has been accelerated by the increased awareness about the adverse effects of the greenhouse gas (GHG) emissions into the atmosphere. The transition includes switching to electricity as the energy carrier in some sectors, e.g. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

   Sammanfattning : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. LÄS MER

4. 3. Dynamic Load Models for Power Systems - Estimation of Time-Varying Parameters During Normal Operation

   Författare :Ines Romero; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage stability; Load modeling; modeling and identification; dynamic load models; normalization in reactive load models;

   Sammanfattning : Economic and environmental concerns will slow down the expansion of the transmission system in many countries. The addition of new transmission lines will be few and far between. The de-regulation of the power supply will introduce new power flow patterns on the bulk transmission systems. LÄS MER

5. 4. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

   Författare :Tahir Naseer Qureshi; Martin Törngren; DeJiu Chen; Ivica Crnkovic; KTH; []
   Nyckelord :Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

   Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER

7. 5. Microwave and millimeter wave CMOS Characterization, modeling, and design

   Författare :Mattias Ferndahl; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-pull; microwave; large-signal; silicon; characterization; modeling; balun; LSNA; frequency doubler; millimeter wave; power amplifier; CMOS;

   Sammanfattning : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. LÄS MER
