High-Performance Deep SubMicron CMOS Technologies with Polycrystalline-SiGe Gates [PDF]

, 2000
The use of polycrystalline SiGe as the gate material for deep submicron CMOS has been investigated. A complete compatibility to standard CMOS processing is demonstrated when polycrystalline Si is substituted with SiGe (for Ge fractions below 0.5) to form

Low order harmonic cancellation in a grid connected multiple inverter system via current control parameter randomization [PDF]

, 2005
In grid connected multiple inverter systems, it is normal to synchronize the output current of each inverter to the common network voltage. Any current controller deficiencies, which result in low order harmonics, are also synchronized to the common ...

Power Loss Minimization and Voltage Profile Improvement by System Reconfiguration, DG Sizing, and Placement

Computation, 2022
A number of algorithms that aim to reduce power system losses and improve voltage profiles by optimizing distributed generator (DG) location and size have already been proposed, but they are still subject to several limitations. Hence, new algorithms can

Optimized Solar Photovoltaic Generation in a Real Local Distribution Network

, 2017
Remarkable penetration of renewable energy in electric networks, despite its valuable opportunities, such as power loss reduction and loadability improvements, has raised concerns for system operators. Such huge penetration can lead to a violation of the

Three Dimensional Electrical Impedance Tomography [PDF]

, 1996
The electrical resistivity of mammalian tissues varies widely and is correlated with physiological function. Electrical impedance tomography (EIT) can be used to probe such variations in vivo, and offers a non-invasive means of imaging the internal ...

Voltage profile improvement of weak grid with solar PV integration

TELKOMNIKA (Telecommunication Computing Electronics and Control), 2021
The objective of this paper is to improve the voltage profile of the grid in pertinence to grid due to power injection from distributed solar photovoltaic (PV) arrays. Weak grids are modeled as worldwide adaptation of net metering, transactive energy systems, and the possibility of further deterioration of power quality with higher grid penetration. In

Voltage profile and power quality improvement in photovoltaic farms integrated medium voltage grid using dynamic voltage restorer

International Journal of Power Electronics and Drive Systems (IJPEDS), 2020
<p class="Abstract">In this paper, we have presented a simulation study to analyze the power quality of three phases medium voltage grid connected with distribution generation (DG) such as photovoltaic (PV) farms and its control schemes. The system uses two-stage energy conversion topology composed of a DC to DC boost converter for the extraction
