The main contribution of this paper is the development of a novel load shedding methodology so as to regulate unacceptable frequency deviations, with least disruption of service, in the case of controlled islanding. To achieve this, an abstracted model of each islanded area, consisting of one lumped generator and turbine model, is used. Since in the controlled islanding the bounds of the areas ...

Wireless Local Area Networks (WLANs) are now commonly available on many academic and corporate Campuses [1]. Load balancing is necessary to improve the network performance. The load may be unevenly distributed across a small number of Access points in the WLAN. In this paper, the load of AP is balanced using load balancing algorithm utilizing Cell breathing technique. Cell breathing is a techni...

Vortex domain patterns in low-dimensional ferroelectrics and multiferroics have been extensively studied with the aim of developing nanoscale functional devices. However, control of the vortex domain structure has not been investigated systematically. Taking into account effects of inhomogeneous electromechanical fields, ambient temperature, surface and size, we demonstrate significant influenc...

Current-source-inverter-based uninterruptible power supplies and V=f -controlled induction motor drives require sensing of two or more load voltages in addition to the dc voltage sensors used for protection purposes. This paper proposes a digital-signal-processor (DSP)-based load voltage control scheme that requires only information provided by the dc-bus voltage sensor. Load voltage estimation...

Abstract—Nowadays, the use of renewable energy sources has been increasingly great because of the cost increase and public demand for clean energy sources. One of the fastest growing sources is wind energy. In this paper, Wind Diesel Hybrid System (WDHS) comprising a Diesel Generator (DG), a Wind Turbine Generator (WTG), the Consumer Load, a Battery-based Energy Storage System (BESS), and a Dum...

We proposed voltage-sourced converter (VSC) with Pulse-width modulation (PWM) provides a faster control that is required for flicker mitigation purpose. The voltage regulation in the distribution feeder is improved by installing a shunt compensator. The proposed DSTATCOM is modeled and its performance is simulated and verified for power factor correction and voltage regulation along with neutra...

The discussion and specifications given here support the IP integrated services...

Automated data collection is essential to effectively measure suspended sediment loads in storm events, particularly in small basins. Continuous turbidity measurements can be used, along with discharge, in an automated system that makes real-time sampling decisions to facilitate sediment load estimation. The Turbidity Threshold Sampling method distributes sample collection over the range of ris...

For estimating suspended sediment concentration (SSC) in rivers, turbidity is generally a much better predictor than water discharge. Although it is now possible to collect continuous turbidity data even at remote sites, sediment sampling and load estimation are still conventionally based on discharge. With frequent calibration the relation of turbidity to SSC could be used to estimate suspende...

In cardiovascular tissue engineering, mechanical stimulation of tissue-engineered constructs is known to improve tissue properties. During tissue culture, the mechanical properties of the tissue construct change. To impose a predefined deformation protocol and to avoid negative effects of excessive strain, it is desired to monitor and control deformations during load application. In a previous ...
