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 ...
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 key review of building integrated photovoltaic (BIPV) systems
(ELSEVIER - DIVISION REED ELSEVIER INDIA PVT LTD, 2017)
Renewable and sustainable energy generation technologies have been in the forefront due to concerns related to environment, energy independence, and high fossil fuel costs. As part of the EU's 2020 targets, it is aimed to ...
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 ...
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 ...
A Model Predictive Control Design for Selective Modal Damping in Power Systems
(IEEE, 2015)
This paper presents a novel real-time predictive control technique to damp dominant inter-area oscillation modes in power systems. We first show that conventional Power System Stabilizers (PSS) in synchronous generators ...
A key review of wastewater source heat pump (WWSHP) systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2014)
Heat pumps (HPs) are part of the environmentally friendly technologies using renewable energy and have been utilized in the developed countries for years. Wastewater is seen as a renewable heat source for HPs. At the ...
