Proactive spectrum sharing incentive for physical layer security enhancement using outdated CSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
We investigate the spectrum sharing possibility as an incentive to enhancing the physical layer security. The concept behind this is that a legitimate source-destination pair, communicating in the presence of a passive ...
A comparison of quadratic TFDs for entropy based detection of components time supports in multicomponent nonstationary signal mixtures
(
IEEE
, 2013 , Conference Paper)
Separation of different signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This paper proposes a fully automatic undetermined blind source separation method, ...
Iterated unscented Kalman filter-based maximum power point tracking for photovoltaic applications
(2013 , Conference Paper)
One of main challenges in harvesting power from a PV source is maximum power point tracking (MPPT). This is due to the nonlinear behaviour and characteristics of PV arrays. Conventional MPPT techniques usually utilize a ...
Maximum power transfer of PV-fed inverter-based distributed generation with improved voltage regulation using flywheel energy storage systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
Quasi two-level operation of modular multilevel converter for use in a high-power DC transformer with DC fault isolation capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
DC fault protection is one challenge impeding the development of multiterminal dc grids. The absence of manufacturing and operational standards has led to many point-to-point HVDC links built at different voltage levels, ...
Fault detection and isolation of Riesz spectral systems: A geometric approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The Riesz spectral (RS) systems represent a large class of parabolic and hyperbolic partial differential equations (PDE) in infinite-dimensional systems. In this work, a fault detection and isolation (FDI) methodology for ...
Transient gas turbine performance diagnostics through nonlinear adaptation of compressor and turbine maps
(
American Society of Mechanical Engineers (ASME)
, 2015 , Article)
Gas turbines are faced with new challenges of increasing flexibility in their operation while reducing their life cycle costs, leading to new research priorities and challenges. One of these challenges involves the ...
Three-wire bipolar high-voltage direct current line using an existing single-circuit high-voltage alternating current line for integrating renewable energy sources in multiterminal DC networks
(
Institution of Engineering and Technology
, 2016 , Article)
When compared with conventional point-To-point high-voltage direct current (HVDC) systems, multiterminal HVDC (MTDC) systems are more economical and flexible. MTDC systems can tie distributed high power renewable energy ...
A space vector PWM scheme for five-phase current-source converters
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
The most recent literature on multiphase machine drives is based on voltage-source converter (VSC) systems utilizing different modulation techniques. Very little attention is given to the multiphase current-source converters ...
Modified modulation scheme for photovoltaic fed grid-connected three-phase boost inverter
(
IEEE
, 2013 , Conference Paper)
Transformer-less photovoltaic (PV) inverters are the major functional units of modern grid-connected PV energy production systems. In general, two power conversion stages are required when low-voltage unregulated photovoltaic ...
