Distributed wide-area control of power system oscillations under communication and actuation constraints
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
In this paper a distributed Model Predictive Control design is presented for inter-area oscillation damping in power systems under two critical cyber-physical constraints namely, communication constraints that lead to ...
Damping wide-area oscillations in power systems: a model predictive control design
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2018)
Electromechanical oscillations in power systems have been observed ever since synchronous generators were interconnected to provide reliability and higher generation capacity, and they have become a severe threat for the ...
A Reduced Order Modeling Methodology for Steam Turbine Clearance Control Design
(ASME, 2017)
Finite element models (FEMs) are extensively used in the design optimization of utility scale steam turbines. As an example, by simulating multiple startup scenarios of steam power plants, engineers can obtain turbine ...
Numerical analysis of a near-room-temperature magnetic cooling system
(ELSEVIER SCI LTD, 2017)
In this study, for a near-room-temperature magnetic cooling system, a decoupled multiphysics numerical approach (Magnetism, Fluid Flow, and Heat Transfer) is developed using a commercial CFD solver, ANSYS-FLUENT, as a ...
An Online Structurally Constrained LQR Design for Damping Oscillations in Power System Networks
(IEEE, 2017)
This paper presents an online distributed control design for suppressing inter-area oscillations in large power systems under structural constraints posed on the underlying communication network. The presence of multiple ...
Performance Assessment of a Near Room Temperature Magnetic Cooling System
(ELSEVIER SCIENCE BV, 2017)
In this study, performance of a near room temperature magnetic cooling system was investigated experimentally in terms of temperature span. The current setup has a permanent magnet pairs (0.7 Tesla), a magnetocaloric ...
Radiant Heating-cooling Performance Assessment in a Shopping Center in Sopron, Hungary
(ELSEVIER SCIENCE BV, 2017)
In this study, performance of a radiant heating-cooling via air source heat pump was investigated. This study is part of a project funded by European Union's FP7 for research, technological development and demonstration. ...
Reduced Order Modeling for Clearance Control in Turbomachinery
(IEEE, 2016)
Finite element models (FEMs) are extensively used in the design optimization of utility scale steam turbines. As an example, by simulating multiple startup scenarios of steam power plants, engineers can obtain turbine ...
Heat exchanger applications in wastewater source heat pumps for buildings: A key review
(ELSEVIER SCIENCE SA, 2015)
Wastewater heat recovery applications are becoming widespread in energy saving applications. A sustainable and low emissions operation in air conditioning and heating processes is achieved by harvesting the otherwise wasted ...
Cloud-based Model Predictive Building Thermostatic Controls of Commercial Buildings: Algorithm and Implementation
(IEEE, 2015)
The contribution of this paper is in two-folds: 1) If more predictive and intelligent control of the thermostat set-points with no explicit models of Root Top Units (RTUs) yet with simplistic lumped parameter thermal models ...
