With the increase of wind power and construction UHVDC transmission, turbines must actively participate in system frequency regulation through inertia response primary to ensure safe stable operation system. However, penetration rate grid structure each regional are different, so that corresponding codes also slightly different. Firstly, this paper introduces specific requirements guidelines ty...

In this paper, a comprehensive real-time dispatch model considering renewable uncertainty based on dynamic load flow (DLF) is proposed. Through DLF, the primary and secondary frequency regulation amount caused by the variation of renewable energy as well as the line flow when primary and secondary regulation are deployed can be obtained easily. Not only the frequency constraints, but also the r...

Slow waves determine frequency and propagation characteristics of contractions in the small intestine, yet little is known about mechanisms of slow wave regulation. We propose a role for intracellular Ca(2+), inositol 1,4,5,-trisphosphate (IP(3))-sensitive Ca(2+) release, and sarcoplasmic reticulum (SR) Ca(2+) content in the regulation of slow wave frequency because 1) 1,2-bis(2-aminophenoxy)et...

Electrical automation technology is a that uses computer technology, information and control principles to optimize the production process, so as improve efficiency. However, there are still some deficiencies in research on energy-saving effect of electrical technology. Based PLC frequency conversion we have carried out experimental pumping unit system. This paper first analyzes necessity const...

This paper presents a novel control system for the participation of plug-in electric vehicles (PEVs) in provisioning ancillary services frequency regulation, way that is transparent to driver and harmonized with smart charging service requirements. Given power-frequency droop curve, which specifies how set PEVs collectively participate regulation (we call this curve “global” curve), we propose ...

emotion regulation strategies are considered as determinant variables on both normal and psychopathological processes. the aim of the present study was to investigate the mediating role of emotion regulation difficulties on the relationship between social anxiety symptoms and anger. a total of 171 participants (71 men, 100 women) from the city of tehran participated in this study as volunteers....

Represented by wind turbines and ultra high-voltage DC (UHVDC), the power-electronic interfaced power sources participate in fast frequency control, which has a significant impact on system frequency. However, conventional under-frequency load shedding (UFLS) scheme doesn’t take into account above, resulting unreasonable after large loss of generation. To this end, article proposes an adaptive ...
