We report a voltage-controlled critical behavior observed in GaAs epitaxial structure containing dense array of ErAs nanoparticles. When fabricated with metal electrodes, the displays voltage- and temperature-dependent metal-to-insulator transition strong hysteresis current versus voltage temperature characteristics, temperatures as high 77 K. Furthermore, we diverging rms deviation electrical ...

HVDC can provide frequency regulation during disturbances (e.g., faults) by controlling the power flow between two remote AC areas. While this action reduces deviation in area affected disturbance, it causes a imbalance other healthy area, leading to variation and endangering system stability. In work, primary voltage-dependent loads (PFR-VDL) is proposed, where terminal influences grid voltage...

In terms of electricity generation, Distributed Generation (DG) using Photovoltaics (PV) panels has become more common. To deal with the potential challenges it brought on the existing electricity distribution network, Demand Side Management (DSM) methodologies are developed. Triana, developed by Computer Architecture and Embedded Systems group (CAES) of University of Twente, is one of them. It...

A tunable temporal photonic fractional differentiator using a silicon-on-isolator (SOI) electrically tuned microring resonator (MRR) is proposed and experimentally demonstrated. Through changing the voltage applied on the MRR, the fractional order of the photonic differentiator can be continuously tuned. The proposed fractional-order differentiator is demonstrated experimentally with Gaussian p...

A power MOSFET linearizer is proposed for a high-voltage power amplifier (HVPA) used in high-frequency pulse-echo instrumentation. The power MOSFET linearizer is composed of a DC bias-controlled series power MOSFET shunt with parallel inductors and capacitors. The proposed scheme is designed to improve the gain deviation characteristics of the HVPA at higher input powers. By controlling the MOS...

This research was conducted to optimize the distribution system using Adaptive Neuro Fuzzy Inference System (ANFIS) method. Objective functions used are to minimize active power loss, node voltage deviation, number of switches, and maintain balance of the feeder. This function is modeled in a fuzzy set to build basic characteristics. The Method has been applied to the 32 bus IEEE standard distr...

This paper presents the application of a fuzzy-logic controller for an AC servomotor. The fuzzy-logic controller is coupled to conventional methods for AC Servo commutation, such as a field-oriented flux control and voltage amplifiers. A test bench platform was designed specifically to test the controller at different load values. The behaviour of the speed and torque variables got stable while...

Abstract Distributed power can effectively alleviate the problems of environmental pollution and energy shortage. Based on consideration low-carbon benefits DG, a multi-objective mathematical model with minimal system carbon dioxide emissions, minimum annual network loss cost, voltage deviation distribution is established for multi-type DG access location capacity.
