An online structurally constrained LQR design for damping oscillations in power system networks
(Proceedings of the American Control Conference, 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 ...
Numerical analysis of a near-room-temperature magnetic cooling system [Analyse numérique d'un système de froid magnétique proche de la température ambiante]
(International Journal of Refrigeration, 2017)
In this study, for a near-room-temperature magnetic cooling system, a decoupled multi-physics numerical approach (Magnetism, Fluid Flow, and Heat Transfer) is developed using a commercial CFD solver, ANSYS-FLUENT, as a ...
Performance Assessment of a Near Room Temperature Magnetic Cooling System
(Energy Procedia, 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
(Energy Procedia, 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. ...
Performance evaluation of a building integrated photovoltaic (BIPV) system combined with a wastewater source heat pump (WWSHP) system
(Energy Procedia, 2017)
This paper deals with both energetic and exergetic performance assessments of two combined systems as a whole. The first one is a Building Integrated Photovoltaic (BIPV) system while the second one is a wastewater (WW) ...
A key review of building integrated photovoltaic (BIPV) systems
(Engineering Science and Technology, an International Journal, 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 ...
Experimental and numerical studies to assess the energy performance of naturally ventilated PV façade systems
(Solar Energy, 2017)
This paper presents a holistic approach to assess the energy performance of a naturally ventilated PV façade system. A rigorous combined experimental and numerical approach is established. The real energy performance of ...
Reduced order modeling for clearance control in turbomachinery
(2016 IEEE Conference on Control Applications, CCA 2016, 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
(Energy and Buildings, 2015)
Abstract 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 ...
A model predictive control design for selective modal damping in power systems
(Proceedings of the American Control Conference, 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 ...
