A key review of building integrated photovoltaic (BIPV) systems

Biyik, E.; Araz, M.; Hepbasli, A.; Shahrestani, M.; Yao, R.; Shao, L.; Essah, E.; Oliveira, A.C.; Del Cano, T.; Rico, E.; Lechon, J.L.; Andrade, L.; Mendes, A.; Atli, Y.B. (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

Shahrestani, M.; Yao, R.; Essah, E.; Shao, L.; Oliveira, A.C.; Hepbasli, A.; Biyik, E.; Cano, T.D.; Rico, E.; Lechon, J.L. (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

Biyik, E.; D'Amato, F.J.; Subramaniyan, A.; Sun, C. (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

Culha, O.; Gunerhan, H.; Biyik, E.; Ekren, O.; Hepbasli, A. (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 ...

Cloud-based model predictive building thermostatic controls of commercial buildings: Algorithm and implementation

Biyik, E.; Brooks, J.D.; Sehgal, H.; Shah, J.; Gency, S. (Proceedings of the American Control Conference, 2015)

The contribution of this paper is in two-folds: 1) If more predictive and intelligent control of the thermostat setpoints 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

Jain, A.; Biyik, E.; Chakrabortty, A. (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 ...

Model predictive building thermostatic controls of small-to-medium commercial buildings for optimal peak load reduction incorporating dynamic human comfort models: Algorithm and implementation

Biyik, E.; Genc, S.; Brooks, J.D. (2014 IEEE Conference on Control Applications, CCA 2014, 2014)

The peak kW of a typical New York State office building is thought to primarily be a function of the HVAC system, often the buildings largest load, but may also be influenced by occupancy and other loads. First, a simple ...

A key review of wastewater source heat pump (WWSHP) systems

Hepbasli, A.; Biyik, E.; Ekren, O.; Gunerhan, H.; Araz, M. (Energy Conversion and Management, 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 ...

Optimal control of microgrids - Algorithms and field implementation

Biyik, E.; Chandra, R. (Proceedings of the American Control Conference, 2014)

A microgrid is a collection of distributed generation assets, storage devices and electrical and/or thermal loads connected to each other. In this paper, a generic model-predictive control algorithm for microgrids is ...

A predictive control strategy for optimal management of peak load, thermal comfort, energy storage and renewables in multi-zone buildings

Biyik, E.; Kahraman, A. (ELSEVIER, 2019)

Buildings are responsible for about 40% of the global energy consumption, where heating, ventilation and air conditioning (HVAC) systems account for the most part of it. Continuous increase in the installation of new HVAC ...
