Future Electricity Networks : How Electrical Car and Solar Panels Impact on the Distribution Electricity Networks (Norwegian)
Abstract [en]

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 that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution. Solar cells have become more popular than ever and that leads to many countries in utilizing their energy needs from solar and the same is going to happen here in Sweden. It is needed to find out how the impacts on the low voltage grids will be if many private individual install solar panels in their own homes and what will happen when they start to supply electricity, which is excess from the production of their solar cells, back to the grid? What should be done in order to maintain the electricity’s quality in term of voltage? Meanwhile, electric vehicle popularity rises every year, which means that electricity demand will rise proportionally with the number of electric cars in the country. Should something be done with the power supply to meet the power needs of electric cars? Is it possible to use the electrical car battery as a backup power? How electric vehicle charging’s behavior will impact on the low voltage? In this project, data and pictures has taken from different sources and consolidated for analysis purpose. This thesis contained information about solar radiation, solar cells, electric vehicles, and batteries, rules for installation of solar cells regulations, electricity grids, and electrical power quality, results of researching and eventual solutions for expected problems.
