Island electricity grids or isolated electricity grids are electrical grids that are not connected to other grids. These grids suffer from low system balance and low power capacity for various reasons (geographical, technical, and other similar aspects). Therefore, all production, transmission, and distribution stages are realized within the network. Electricity generation on an island grid requires constant transportation of fossil fuel to the island, increasing the cost of electricity, and the volatility of the system. Renewable energy sources received attention in recent years to solve this problem. Still, due to the nature of uncertainty of renewables, it is not possible to use this kind of source in full performance. With the development of advanced power electronics, energy transmission with High Voltage Direct Current (HVDC) to islands has become an option. Due to the expensive nature of this option, detailed analysis and comparison are required for island grids. In this thesis, a North Cyprus island grid model is developed with an HVDC interconnection option to Turkey and used for the techno-economic study to compare HVAC and traditional fossil fuel investments. The mentioned techno-economic analysis combines optimal power flow with traditional economic cost calculation methods. Ultimately, a better option among the suggested scenarios is evaluated for further research.

Grid impedance estimation based adaptive controller design for back-to-back wind turbine power converters for stable operation in distorted and weak grid Temiz, Hakan; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019) This thesis involves grid impedance estimation based adaptive controller design for back-to-back wind turbine power converters for stable operation in distorted and weak grid. The study focuses on the low frequency harmonic elimination of injected current to the grid under distorted grid conditions and maintaining system stability under wide range of grid impedance values for Voltage Source Inverters (VSIs) connected to the grid via LCL filter. To eliminate 5th and 7th harmonics of the injected current, a c...
Seismic strengthening of a mid-rise reinforced concrete frame using CFRPs: an application from real life Tan, Mustafa Tümer; Özcebe, Güney; Department of Civil Engineering (2009) FRP retrofitting allows the utilization of brick infill walls as lateral load resisting elements. This practical retrofit scheme is a strong alternative to strengthen low to mid-rise deficient reinforced concrete (RC) structures in Turkey. The advantages of the FRP applications, to name a few, are the speed of construction and elimination of the need for building evacuation during construction. In this retrofit scheme, infill walls are adopted to the existing frame system by using FRP tension ties anchored ...
Hybrid excited synchronous generator design and comparison of direct drive wind turbines Akgemci, Aysel; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019) Various types of electrical generators are used in wind turbines and there is not an agreement on the best generator type. Although, high speed Doubly Fed Induction Generators (DFIGs) are still the most common generator topology utilized in wind turbine systems, there is a trends toward direct-drive Permanent Magnet Synchronous Generators (PMSGs), as they are more efficient and reliable. However, permanent magnets (PMs) induce uncontrollable voltage due to the fixed flux resulting from PM excitation. Conven...
Leakage current and energy efficiency analyses of single phase grid connected multi-kva transformerless photovoltaic inverters Özkan, Ziya; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2012) In order to inject solar power to the utility grid, among various types of inverters, Grid Connected Transformerless Solar Inverters (GCTSI) are mostly preferred for residential or commercial applications. This preference is because of the high energy efficiency and low cost due to the absence of a line frequency or a high frequency transformer. Peak value of the efficiency characteristics of GCTSIs can reach 98%, which are selected topology, component optimization, switching strategy and operating conditio...
Beam modulation in double gap virtual cathode oscillator Küçük, İbrahim Semih; Demir, Şimşek; Department of Electrical and Electronics Engineering (2018) Vircator is a promising high power microwave device when its simplicity, frequency tunability, lack of external magnetic field source are considered. Vircator gains importance especially susceptibility testing to electromagnetic pulses of electronic equipments with its tunability. Apart from advantages, main bottleneck of the vircator is its low efficiency. Tunability and efficiency enhancement studies are still continued in literature. Double gap vircator draws attention due to its tunability, generation f...
