Özet:

Renewable energy systems offer sustainable solutions for the energy need of the world. Hybrid systems can be an alternative for remote off-grid houses that do not have connection to the electricity grid. This study examines sizing of an islanded wind-solar-battery power system for a zero-energy house that does not have a grid connection in Afyon Turkey. For this remote house, continuous power supply is an essential requirement and the designed system must guarantee reliable uninterrupted supply of power to the house. In an off-grid wind-solar-battery hybrid system, if different rated wind turbines and/or different number of solar panels are used in the system, the minimum number of batteries needed in the hybrid system would be different in order the meet the uninterrupted continuous power supply requirement. In practice it is the usual case that, due to incompatible hybrid system components the consumers suffer from no electric power occasionally. In this study, using power consumption data of the considered remote house and actual wind and solar measurement data of Afyon site, sizing analysis for a hybrid wind-solar-battery power system is done. For a sizing analysis, calculations that use actual small time interval data are essential to ensure uninterrupted continuous power from a hybrid system.
