The operational economics of compressed air energy storage systems under uncertainty 

Yucekaya, Ahmet (Pergamon-Elsevier Science Ltd, 2013)
A Compressed Air Energy Storage System is a means of storing energy which can then be used when the demand for energy increases. In this system air is compressed in a cavern when power prices are low and this air is used ...

Harmony Search Algorithm Based Management of Distributed Energy Resources and Storage Systems in Microgrids 

Ceylan, Oğuzhan; Sezgin, Mustafa Erdem; Goel, Murat; Verga, Maurizio; Lazzari, Riccardo; Kwaye, Marcel Pendieu; Sandroni, Carlo (MDPI, 2020)
Microgrids are composed of distributed energy resources (DERs), storage devices, electric vehicles, flexible loads and so on. They may either operate connected to the main electricity grid (on-grid operation) or separated ...

Accurate indoor positioning with ultra-wide band sensors 

Arsan, Taner (Tubitak, 2020)
Ultra-wide band is one of the emerging indoor positioning technologies. In the application phase, accuracy and interference are important criteria of indoor positioning systems. Not only the method used in positioning, but ...

An Adaptive Affinity Matrix Optimization for Locality Preserving Projection via Heuristic Methods for Hyperspectral Image Analysis 

Taşkın, Gülşen; Ceylan, Oğuzhan (IEEE-Inst Electrıcal Electronıcs Engıneers Inc, 2019)
Locality preserving projection (LPP) has been often used as a dimensionality reduction tool for hyperspectral image analysis especially in the context of classification since it provides a projection matrix for embedding ...

Towards Faster Branch Outage Simulations Using Simulated Annealing and Parallel Programming 

Ceylan, Oǧuzhan; Ozdemir, Aydogan; Daǧ, Hasan (IEEE, 2009)
Contingency studies such as branch outage and generator outage are among important studies of energy management centers operations. Branch outage modeling on the other hand is one of the basic steps of post-outage state ...

Optimization of Graph Affinity Matrix with Heuristic Methods in Dimensionality Reduction of Hypespectral Images 

Ceylan, Oğuzhan; Taşkın, Gülşen (IEEE, 2019)
Hyperspectral images include hundreds of spectral bands, adjacent ones of which are often highly correlated and noisy, leading to a decrease in classification performance as well as a high increase in computational time. ...
