1. 1. Balancing Supply and Demand in an Electricity System - the Case of Sweden

   University essay from KTH/Industriell ekonomi och organisation (Inst.)

   Author : Oskar Mared; Victor Persson; [2018]
   Keywords : Electricity System; Intermittent Energy Sources; Balancing Supply and Demand; Frequency Control; Local Balancing Efforts; Socio-Technical Approach; Multi-Level Perspective; elsystem; intermittenta energikällor; balansera produktion och konsumtion; frekvensreglering; balansering på lokal nivå; socio-teknisk ansats; flernivåsansats;

   Abstract : In an electrical system there needs to be a constant balance between supply and demand ofelectricity and this is measured by the frequency in the grid. Due to the increasing awarenessof climate change, more renewable energy resources have been introduced in the Swedishelectricity system. READ MORE

3. 2. Test Grids for Reliability analysis : Analysing interruptions and developing test grids based on Mälarenergi Elnät distribution grid

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Jonas Eld; Jens Melin; [2017]
   Keywords : ;

   Abstract : The purpose of this degree project is to examine power outages that has occurred during the years 2009 and 2016 on Mälarenergi Elnät distribution grid. Interruptions that has occurred on 10 kV voltage level and on overhead lines or underground cable was examined. The examined interruptions are based on the DARWin data from Mälarenergi Elnät.

4. 3. Impact Study: Photo-voltaic Distributed Generation on Power System

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Smrutirekha Sahoo; [2016]
   Keywords : DC-AC inverter; DC-DC boost converter; Dynamic PV model; Grid-connected PV system; Harmonic distortion; LV grid-modelling; Overvoltage; THD; Voltage unbalancing; VSI;

   Abstract : The grid-connected photo-voltaic (PV) system is one of the most promising renewable energy solutions which offers many benefits to both the end user and the utility network and thus it has gained the popularity over the last few decades. However, due to the very nature of its invariability and weather dependencies, the large scale integration of this type of distributed generation has created challenges for the network operator while maintaining the quality of the power supply and also for reliable and safe operations of the grids.

5. 4. Spatial patterns of pollution associated with creosote treated poles in Mälardalen

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Ellen Forselius; [2015]
   Keywords : ;

   Abstract : Creosote is a product name given to a mixture of several hundred compounds, which is often used to protect wooden poles from rot and insect damage, however it has also been linked to causing cancer in humans. Alternative materials for power poles include concrete, steel, composite and non-treated wooden poles. READ MORE

6. 5. Optimization of Section Points Locations in Electric Power Distribution Systems : Development of a Method for Improving the Reliability

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Joakim Johansson; [2015]
   Keywords : Primary distribution system; Mälarenergi Elnät; loop structure; radially operated; section point locations; switches; power system reliability; optimization algorithm; analytical technique; FMEA; Mellanspänningsnät; Mälarenergi Elnät; slingnät; radialnät; sektioneringspunkt; frånskiljare; brytare; tillförlitlighet; optimerings algoritm; analytisk teknik; FMEA;

   Abstract : The power distribution system is the final link to transfer the electrical energy to the individual customers. It is distributed in a complex technical grid but is associated with the majority of all outages occurring. Improving its reliability is an efficient way to reduce the effects of outages. READ MORE
