Application of distance relay for distribution system monitoring
(
IEEE Computer Society
, 2015 , Conference Paper)
The traditional distribution network is primarily composed of radial feeders, designed for unidirectional power flow. Therefore, many operation regulation, protection and control system, in distribution network, are based ...
Discontinuous space vector pulse width modulation techniques for a five-phase quasi Z-source inverter
(
IEEE
, 2015 , Conference Paper)
In this paper, discontinuous space vector pulse width modulation for a five-phase quasi Z-source inverter is presented. Two schemes are introduced for the continuous SVM of five-phase qZSI (SVQ1 & SVQ2) and two schemes of ...
Geometrical approach for wind farm symmetrical layout design optimization
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Wind farm layout orientation plays an important factor to reduce the total wake loss and hence increase the capacity factor of the wind farm. Different wind farms layout design optimization techniques are widely used and ...
Simple voltage regulation method for smart grid applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The complexity of power systems and the change of demand load at the consumer make it necessary to control the voltage to avoid any unnecessary voltage drop beyond the limits allowed within the international standards and ...
Implementation of iterative learning control based deadtime compensation for PWM inverters
(
IEEE
, 2015 , Conference Paper)
Deadtime effects in PWM inverters are nonlinear and depend on the switching frequency of the inverters and the types of power devices, snubber circuits, and loads. Several deadtime compensation methods were proposed in the ...
ANN-based extraction approach of PV cell equivalent circuit parameters
(
IEEE
, 2015 , Conference Paper)
In most practical cases, a PV array is constructed from a combination of standard PV units (solar cells or panels) connected in series and/or in parallel to obtain the desired power, voltage and current ratings. However, ...
Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters
(
IEEE
, 2015 , Conference Paper)
Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great ...
Histogram-based thresholding in discrete wavelet transform for partial discharge signal denoising
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
White noise is a major interference source that affects the partial discharge (PD) signal detection and recognition. Wavelet shrinkage denoising methods can efficiently reject the white noise embedded in the PD signal ...
Progressive recovery for cloud-based infrastructure services
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Cloud-based services allow users to outsource their application and infrastructure needs over external datacenter/ networking facilities. However, as these offerings gain traction, there is a pressing need to address ...
Flexible advance reservation models for virtual network scheduling
(
IEEE Computer Society
, 2015 , Conference Paper)
Advance reservation services allows users to pre-reserve network resources at future instants in time. These offerings are already being used by a wide range of applications in scientific/grid computing, datacenter backup, ...
