moreThe world is about to enter a future where the integration of renewable energy sources within the power grid will play a major part when facing the challenge of reducing global warming. The implementation of microgrids might prove to be a good solution to handle the intermittent generation characteristics associated with renewable energy sources. The Swedish law and regulations does not currently favour the usage of the fundamental technology needed to implement a microgrid. The purpose of this thesis is to investigate the environmental and economical impact of implementing a microgrid. By making calculations and assumptions on the consumption data for the town of Glesby, a model to find an optimally dimensioned battery storage system is formulated and the economical viability of using a microgrid for the towns already existing wind power plant is presented and discussed. Revenue streams from the concepts of demand flexibility and ancillary services are examined as well. The report concludes that investing in a microgrid using demand flexibility, supplying ancillary services to the main grid and utilising a properly dimensioned battery energy storage system will be a feasible solution for the future integration of local renewable energy sources. In order to accomplish this, the suggested legislative changes presented in the thesis needs to be made.
