Abstract [en]

The possibility to use wind power directly in a house to replace part of the used electricity is examined here theoretically. Measured climate data from Finland, Vanda airport at 10 meters height, are used for outdoor temperature and wind data. This data is simulated for 8 different wind turbine power output and a case study residence building is used for the energy demand. The energy demand consists of heating, hot water and electrical equipment. If wind production is higher than energy demand then the remaining energy is stored in one electrical battery or the buildings hot water boiler. Additional excess energy is delivered free to the network and does not taken into account into the energy balance of the building. The 8 different small scale wind turbine options and the energy demand of the house are compared and the profitability of each system is assessed. Based on the available data, excel is used to calculate the energy production and demand over a year based on hourly temperature and wind speed measurements. Some suggestions for further research are given at the end.
