With a model of renal blood flow regulation, we examined consequences of tubuloglomerular feedback (TGF) coupling to the myogenic mechanism via voltage-gated Ca channels. The model reproduces the characteristic oscillations of the two mechanisms and predicts frequency and amplitude modulation of the myogenic oscillation by TGF. Analysis by wavelet transforms of single-nephron blood flow confirm...

The large-scale grid connection of photovoltaic power generation results in the system frequency fluctuation and regulation capacity decline, which endangers dynamic security frequency. In order to reduce deviation tap potential participating regulation, a control method is proposed this paper. maximum allowable predicted through identification, load shedding rate determined based on this, outp...

The continuous improvement of new energy penetration reduces the inertia system, which leads to frequency deviation and rate change (RoCoF) being easily exceeded. To improve stability sending-end power systems with large-scale renewable access via ultra-high voltage direct current (UHVDC), coordinated control for UHVDC participating in system regulation (FR) including primary FR inertial respon...

Hybrid ac/dc networks are a key technology for sustainable electrical power systems, due to the increasing number of converter-based distributed energy resources such as solar or wind. In this article, we consider design control schemes hybrid networks, focusing especially on interlinking converters (ILCs). We present two schemes: first decentralized primary and second controller achieve second...
