摘要：This paper is to investigate whether the energy demand of Pinarhisar educational campus in KırklareliUniversity is fully met by using various types of the renewable power generating systems and also search forthe optimum configuration of the hybrid power generating systems. Wind speed and solar radiation datameasured in an hourly time-series format are used based on 2 years between 2008 and 2010, respectively.Three different renewable power generating systems, standalone PV- Battery and standalone Wind-Batteryand standalone PV-Wind systems, are analyzed in detail by using HOMER software and compared amongthemselves considering COE, total NPC. Additionally, sensitivity analysis is performed considering threedifferent wind speed values because of the wind’s instable nature. According to the study results, the optimalconfiguration with the lowest total net present cost (NPC) and cost of energy (COE) contains one wind turbine,36 batteries, a 6 kW converter and the 14kW PV array under the current conditions in Pinarhisar region(average wind speed and average solar global irradiance are almost 3.94 m/s and 4.98 kWh/m2/d,respectively.). Finally, this study also searches for how much NPC and COE values of the hybrid powergenerating systems show a tendency of increasing or decreasing remarkably based on the amount of thechange in the (variable and unstable stable) wind speed.
