Impact of high-level distributed generation penetration on the transmission system transient stability
Kurt, Burçak; Ertaş, Arif; Department of Electrical and Electronics Engineering (2009)
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 star...
Impact of Demand Stochasticity on Facility Layouts
Efeoglu, Begun; Çelik, Melih; Süral, Haldun (2016-07-03)
This study investigates the effect of demand uncertainty and the relayout cost on the choice of layout type in stochastic facility layout problems. To evaluate layout flexibility, alternative performance measures other than total material handling cost are defined. Using a twostage scenario-based stochastic integer programming, we simulate its results in order to measure operational performance of the system in a dynamic environment. We then use dynamic programming model to explore the effect of the relayou...
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...
Impact of hydrologic uncertainties in reservoir routing
Kentel Erdoğan, Elçin; Yanmaz, Ali Melih (null; 2008-05-27)
Reservoir routing methods are used in the design and operation of storage facilities at high flow conditions. Traditionally, deterministic approaches have been used for reservoir flood routing computations, which do not account for possible variations in governing parameters. However, hydrologic variables, such as inflow, stage, and outflow may naturally have various sources of uncertainties. Since important dimensions, such as dam height and spillway size, are normally dictated by reservoir routing perform...
Impact of physical and chemical heterogeneities on optimal remediation design and costs
Aksoy, Ayşegül (null; 2001-01-24)
The impact of physical and chemical aquifer heterogeneities on optimal remediation design and costs is investigated by linking a genetic algorithm optimization library with a contaminant transport simulation model. Various levels of physical and chemical (sorption) aquifer heterogeneities are examined. In the first level, heterogeneity is limited to the hydraulic conductivity (K) field. Then systems with heterogeneity in both K and the distribution coefficient (Kd) are considered. The final level of heterog...
