Hur elbilar och solceller påverkar på det lokala elnätet
The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so …
… to use to produce energy as well as to store that energy. To produce heat and electricity to the house I decided to use a wind turbine and a solar water heater. The most difficult part of designing a house that is energy independent is that the produced energy must be stored …
The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. The use of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere. This is the main motive but also a wish of higher safety, that is a higher rate of …
Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise …
… AB. At present time, BAE Systems Hägglunds AB are developing a 6-wheel electrical hybrid and a conventional 8-wheel vehicle. The question formulation was summarized as: ?In which ways can the electrical transmission in a hybrid driveline for SEP be designed, when the surrounding …
… allocation ? a study of how Swedish energy companies allocate costs between electricity and district heating in a combined heat and power plant District heating is today the most utilized alternative for heating in Sweden. In a combined heat and power plant (CHP) electricity and …
… consumption. The transition time for this change was due July 2009. Hence all electric companies had to find a solution to automatically collect meter data before that date. For those of you who earlier have not been involved in the business areas of electricity and power there …
