Determination Of The Optimum Renewable Power Generating Systems For An Educational Campus In Kirklareli University

Abstract

This paper is to investigate whether the energy demand of Pinarhisar educational campus in Kirklareli University is fully met by using various types of the renewable power generating systems and also search for the optimum configuration of the hybrid power generating systems. Wind speed and solar radiation data measured 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-Battery and standalone PV-Wind systems, are analyzed in detail by using HOMER software and compared among themselves considering COE, total NPC. Additionally, sensitivity analysis is performed considering three different wind speed values because of the wind's instable nature. According to the study results, the optimal configuration 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/m 2 /d, respectively.). Finally, this study also searches for how much NPC and COE values of the hybrid power generating systems show a tendency of increasing or decreasing remarkably based on the amount of the change in the (variable and unstable stable) wind speed.
