Load shedding control is an emergency measure to maintain the frequency stability of power system. Most existing load methods use extensive form directly cutting off outlet substation, featuring low accuracy and high cost. A network reconfiguration technique can adjust topology distribution offers more optimization space for control. Therefore, this paper proposes a reconfiguration–load coordin...

This paper proposes a new load shedding method based on the application of intelligent algorithms, process calculating and is carried out in two stages. Stage-1 uses backpropagation neural network to classify faults system, thereby determining whether or not shed that particular case. Stage-2 an artificial combined with ant colony algorithm (ANN-ACO) determine strategy. The AHP applied propose ...

Submarine pipelines are appropriate method for transmission of oil and gas from sea bed. Free spans may occur due to the natural uneven seabed or by under-scouring. Vortex Induced Vibration (VIV) can happen in such free spans at high Reynolds number. Resonance occurs if the frequency of vortex shedding is close to the pipeline’s natural frequency leading to its fatigue that can break the pipeli...

BACKGROUND This study was done to characterize parameters associated with semen human immunodeficiency virus (HIV)-1 ribonucleic acid (RNA) viral load (VL) variability in HIV-infected, therapy-naive men. METHODS Paired blood and semen samples were collected from 30 HIV-infected, therapy-naive men who have sex with men, and 13 participants were observed longitudinally for up to 1 year. Human i...

We present the design of a predictive load shedding scheme for a network monitoring platform that supports multiple and competing traffic queries. The proposed scheme can anticipate overload situations and minimize their impact on the accuracy of the traffic queries. The main novelty of our approach is that it considers queries as black boxes, with arbitrary (and highly variable) input traffic ...

Because of the high volume and unpredictability arrival of data streams, stream processing systems may not always be able to keep up with the input — resulting in buffer overflow and uncontrolled loss of data. Load shedding, the prevalent strategy for solving this overflow problem, has todate been considered for relational stream engines. On the other hand face additional challenges and opportu...

This paper presents a mixed integer linear programming formulation for load-side control of electrical energy demand. The formulation utilizes demand prediction to determine if control actions are necessary, and it schedules both shedding and restoration times based on an optimization model that minimizes the net cost of load shedding. Operational constraints are satisfied through the use of mi...

A new electromagnetic energy harvester for harnessing energy from vibration induced by Kármán vortex street is proposed. It converts flow energy into electrical energy by fluid flow, vortex shedding from a bluff body and electromagnetic induction. An analytical design method for the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. The prototype has a ...
