Master Thesis Techno-Economic Optimization of Pv-Wind Hybrid Systems(01. Izmir Institute of Technology, 2023) Demirdal, İlke; Çağlar, Başar; Çağlar, Başar; 03.06. Department of Energy Systems Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyIn this study, the technoeconomic optimization of hybrid renewable energy systems were investigated for a small community with 50 households located in Izmir Institute of Technology (IZTECH) Campus, Izmir. The renewable-based power systems have received significant attentions recently due to the recent effort for the transition from fossil fuels to renewable energy, but their technical and economical feasibilities for different sectors and application areas and the related optimum system configurations haven’t been clearly addressed. To fill this research gap, PV-battery and wind turbine-battery system were analyzed for a small community from technical and economic point of views and the most economic configurations were explored for different level of grid-dependency by using the Loss of Power Supply Probability (LPSP) method. The annual electricity load profile was built in hourly basis based on the monthly total electricity consumption of each house and electricity consumption habits of residents. PV and wind turbine power outputs, the involvement of batteries were modelled in MATLAB/Simulink considering the meteorological data (IZTECH Meteorological Mast and NASA POWER), types of PV panel, wind turbine and battery. The mismatch between energy demand and supply was determined and different hybrid configurations were considered to cover this mismatch to different extents. The optimum number of PV panel, wind turbine and batteries were determined and the levelized cost of electricity were calculated for each scenario. The most economic configuration is the one consisting of 3 wind turbines and 7 batteries with 49.62% energy utilization from the grid.Master Thesis Optimization of a Hybrid Combination of a Photovoltaic Syste and a Wind Energy Conversion System: Izmir Institute of Technology Campus Area Case(Izmir Institute of Technology, 2003) Ekren, Orhan; Özerdem, Barış; Özerdem, Mehmet Barış; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyRenewable energy resources have gained the great importance due to the growing concerns of environmental problems. The integrated utilization of renewable energies such assolar and wind are becoming very attractive, especially, in most of the isolated and remote areas in many parts of the world.In the present study, firstly, wind and solar radiation measurements, made on Izmir Institute of Technology (IZTECH) Campus area, have been analyzed in order to determine the, both, solar and wind energy potentials of the location. The monthly average wind speeds range from 5.7 m/s to 7.7 m/s, the monthly average of daily values of solar radiation range from 2.1 kWh/m2 to 5.7 kWh/m2 at the monitoring station throughout the measurement period of 12 months between 01.01.2002 and 31.12.2002.Secondly, a procedure is described which determines the hybrid system parameters such as photovoltaic (PV) array area and rotor swept area of wind turbine while satisfying a specific load distribution. The employed method is a graphical construction to figure out the optimum configuration of the generators that satisfies the energy demand mentioned above.
