Abstract

© 2018 International Journal of Renewable Energy Research.For remote houses with no connection to the grid, if the site is suitable for wind energy, an off-grid wind turbinebattery power system is a good alternative for supplying the energy need of the house. If the reliability of the power supply is crucial then sizing of the components, wind turbine and the battery bank, is very important. In the market there are many wind turbines with different ratings and power curves. For an off-grid turbine-battery power system, for every different chosen wind turbine the minimum required number of batteries in the battery bank would be different for reliable and continuous power supply to the house. It is the usual case in practice that either the battery bank is chosen as undersized such that the consumer suffers from no power from time to time or the battery bank is chosen as oversized without any calculation and this results in high initial costs for the consumer. In this study, for a remote house in Catalca Turkey, a stand-alone wind turbine-battery system will be sized using wind data of the site and consumption data of the house. Our results show that the minimum number of batteries needed in the battery bank for an uninterrupted electrical energy supply changes very much according to the chosen wind turbine and the minimum required number of batteries depends on the power curve of the chosen wind turbine rather than the rated power of the wind turbine.
