    A note on applications of time-domain solution of Cole permittivity models
    (Elsevier Gmbh, 2017) Alagoz, Bads Baykant; Alisoy, Gulizar; Alagoz, Serkan; Alisoy, Hafiz
    The complex dielectric permittivity is an important parameter for characterization of electrical properties of dielectric materials. Experimental studies demonstrated that Cole models of dielectric permittivity can provide a better fitting to the experimental data because of allowing for fractional-order frequency dependence. This study aims to investigate physical interpretation of time domain solutions of Cole permittivity models. For this purpose, impulse responses of Cole-Cole model and Davidson-Cole model are expressed in Mittag-Leffler function form by using inverse Laplace transform. The impulse responses of these models are decomposed into impulsive and dispersive components, and the relations of these components with relaxation mechanism of dielectric materials are discussed. By considering impulse response solution of Cole-Cole models, a fractional order dynamic capacitance model is introduced for time domain equivalent circuit modeling of dielectric materials. Moreover, transient properties of electromagnetic wave penetration to dielectric materials are analyzed according to impulse response solution of Cole-Cole model. To illustrate applications of proposed time domain permittivity solutions, the Cole-Cole model of ethyl-acetate liquids was also studied and results are presented. (C) 2017 Elsevier GmbH.

    A smart building power management concept: Smart socket applications with DC distribution
    (Elsevier Sci Ltd, 2015) Keles, Cemal; Karabiber, Abdulkerim; Akcin, Murat; Kaygusuz, Asim; Alagoz, Bads Baykant; Gul, Ozan
    Recent developments in power electronics increase DC bus utilization in electrical distribution systems due to its numerous advantages compared to AC distribution system in term of energy efficiency, safety, electromagnetic compatibility and renewable energy integration. This study presents a power management system concept based on domestic DC distribution with smart sockets for future smart houses. Energy efficient smart buildings are possible by integrating smart meter, smart sockets, domestic renewable energy generation and energy storage systems for integrated energy management, and this integrated system supports demand side load management, distributed generation and distributed storage provisions of future smart grids. Coming era of smart grids has implications for domestic DC distribution concepts with smarts sockets. Paper describes use of smart DC sockets as an integral part of building power management automation and presents a load shedding algorithm for plug load control for buildings. Simulations show performance of the proposed system components. (C) 2014 Elsevier Ltd. All rights reserved.
