As a growing number of microgrids (MGs) has been integrated into the modern power grids, interconnection and applicable cooperation among multiple MGs motivate development networked MGs. Dynamic MGs, as an advanced structure, can not only integrate distribution system but also fulfill requested network reconfiguration with improved flexibility. A general distributed control approach for is revi...
Due to magnetic saturation, the small-signal admittance of an induction motor is dependent on the direction of the excitation signal. The angle-dependence of the admittance can be used in the estimation of the flux angle, and it should be taken into account when identifying motor parameters. In this paper, the small-signal admittance of a 2.2-kW induction motor is measured at different excitati...
Microgrids are often considered as the solution for affordable and clean energy in distribution sector. This article presents small-signal stability analysis of a distributed generation unit an autonomous microgrid operation. The purpose proposed strategy is to optimally improve capacity power system restore reasonable operating condition following small physical disturbance. joined execution b...
background: eukaryotic proteins generally have signal peptides, which are not only crucial for their secretion efficiencies but are important for their expression levels. the coagulation factor ix (fix) is a glycoprotein that plays a fundamental role in a blood coagulation pathway. reduced levels or dysfunctional fix are associated with hemophilia b. to improve the hfix secretion efficiency in ...
Heterostructure field effect transistors (HFETs) are based on AlGaN/GaN heterostructures which offer excellent electronic properties for the development of faster, heat-resistant , energy efficient transistors and application in microwave-power amplifiers [1,2]. The outstanding device performance in cut-off frequency, breakdown voltage, and device output power [3,4]. However, the comparatively ...
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
