This thesis investigates the impact of high-level penetration of distributed generation especially from the renewable energy sources on the transient stability of the transmission system. Distributed generation is a source of electric power connected to the distribution network or on the consumer side. It is expected that distributed generation grows significantly by the increasing environmental concerns and deregulation in the market. As soon as the increasing penetration level, distributed generation starts to influence the distribution system as well as the transmission system. To investigate the impact of distributed generation with different penetration levels on the transmission system transient stability, simulation scenarios are created and simulations are run on the basis of these scenarios by the implementation of the different distributed generation technologies to the “New England” test system. Stability indicators are observed to assess the impact on the transient stability. Results are presented throughout the thesis and the impact of the different distributed generation technologies and the different penetration levels on the transient stability is discussed by comparing the stability indicators.

Impact of defected ground structures on the bandwidth of quarter wave impedance transformers and branch line hybrids
Polater, Ahmet Mert; Nesimoglu, Tayfun (Wiley, 2016-05-01)
In this article, impedance transformers and branch line hybrids are selected to demonstrate the impact of defected ground structures on the operational bandwidth of microwave circuits. Three different branch line hybrids are studied with simulations and laboratory measurements, these are; a standard branch line hybrid, one using tapered lines and another one using both tapered lines and DGS. Based on these results, an optimum design in terms of location, size and number of DGS was proposed to achieve the wi...
Continuation power flow and voltage stability in power systems
Keskin, Mehmet B; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007)
This thesis investigates an important power system phenomenon, voltage stability, by using continuation power flow method. Voltage collapse scenario is presented which can be a serious result of voltage instability and the parameters that affect voltage collapse are discussed. In analyzing power system voltage stability, continuation power flow method is utilized which consists of successive load flows. This method is applied to a sample test system and Turkish Power System and load-voltage curves for sever...
The effects of hydro power plants’ governor settings on the turkish power system frequency
Cebeci, Mahmut Erkut; Ertaş, Arif; Department of Electrical and Electronics Engineering (2008)
This thesis proposes a method and develops a mathematical model for determining the effects of hydro power plants’ governor settings on the Turkish power system frequency. The Turkish power system suffers from frequency oscillations with 20 30 seconds period. Besides various negative effects on power plants and customers, these frequency oscillations are one of the most important obstacles before the interconnection of the Turkish power system with the UCTE (Union for the Coordination of Transmission of El...
OPTIMAL CONTROLLER DESIGN FOR SPEED GOVERNORS OF HYDROELECTRIC POWER PLANT
Altinoz, Okkes Tolga; KOŞALAY, İLHAN; Gezer, Derya (VSB - Technical University of Ostrava, 2020-06-01)
Speed governors have critical importance on hydroelectric power plants, which are adjusted to the rotating speed of hydroelectric generation based on load demand of the grid. The rotating speed is the main factor to balance power generation and load demand. The well-designed controller is needed to control speed governors with high accuracy. A well-defined model is needed to obtain desired control structure. Therefore, in this study, initially, the mathematical model of a hydroelectric power plant is obtain...

Bağlan, Fuat Onur; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2008)
In this thesis a multifunctional DC/DC converter board will be developed for utilization as an educational experiment set in the switched-mode power conversion laboratory of power electronic courses. The board has a generic power-pole structure allowing for easy configuration of various power converter topologies and includes buck, boost, buck-boost, flyback, and forward converter topologies. All the converters can be operated in the open-loop control mode with a switching frequency range of 30-100 kHz and ...
