Changes in Farm Supply Voltage Caused by Switching Operations at a Wind Turbine

open access: yesEnergies
Renewable electricity sources are now widely used worldwide. Currently, the most common sources are those that use energy contained in biomass, water, sun, and wind. When connected to a medium-voltage grid, individual wind power plants must meet specific

Nonlinear Analysis and Control of Interleaved Boost Converter Using Real-Time Cycle to Cycle Variable Slope Compensation [PDF]

open access: yes, 2017
Switched-mode power converters are inherently nonlinear and piecewise smooth systems that may exhibit a series of undesirable operations that can greatly reduce the converter's efficiency and lifetime.

On the switching control of the DC–DC zeta converter operating in continuous conduction mode

open access: yesIET Control Theory & Applications, 2021
Here, a switching control mechanism for the stabilization of a DC–DC zeta converter operating in continuous conduction mode is proposed. The switching control algorithm is based on a control Lyapunov function and extends the method proposed for a two ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Simulation of Electromagnetic Fields Emitted from GIS Bushing Due to Disconnectors Switching Operation in 1000 kV Substations

open access: yesCSEE Journal of Power and Energy Systems
Switching operations of disconnectors emit electromagnetic fields (EMF) to the external environment via gas-to-air bushing, posing a threat to the secondary equipment in gas-insulated substations (GIS) and potentially causing telecommunications outages ...

Analysis and design of a high gain non-isolated zero current switching bidirectional DC–DC converter for electric vehicles

open access: yesAutomatika, 2019
This paper presents a dual inductor based current-fed bidirectional non-isolated DC–DC converter for energy storage applications. The main idea of this converter is to achieve a higher voltage conversion ratio by obtaining the operation of zero current ...

Simulation of Self-Healing in Samawa City Distribution System [PDF]

open access: yesEngineering and Technology Journal, 2020
Self-healing is the ability of a distribution system to automatically restore power after permanent faults. This paper investigates the impact of outages in the distribution network elements following the occurrence of a fault.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

High Multiplicity Scheduling with Switching Costs for few Products

open access: yes, 2014
We study a variant of the single machine capacitated lot-sizing problem with sequence-dependent setup costs and product-dependent inventory costs. We are given a single machine and a set of products associated with a constant demand rate, maximum loading
