Accurate event identification is an essential part of situation awareness ability for power system operators. Therefore, this work proposes integrated algorithm systems. First, to obtain and filter suitable inputs identification, detection trigger based on the rate change frequency (RoCoF) presented. Then, wave arrival time difference-based triangulation method considering anisotropy propagation speed utilized estimate location detected event. Next, two-dimensional orthogonal locality...
The increasing penetration of renewable generation presents challenges for system frequency regulation due to short-term power fluctuations and inertia reductions. This article a coordinated control strategy in which inverter air-conditioning (IAC) units are used perform primary (PFR) fixed (FFAC) secondary (SFR). In PFR, the is provided by adjusting setpoints IAC units. A random number method proposed stochastically trigger based on deviation real time. Furthermore, recovery presented...
The declining cost of solar Photovoltaics (PV) generation is driving its worldwide deployment. As conventional with large rotating masses being replaced by renewable energy such as PV, the power system's inertia will be affected. a result, frequency may vary more dramatically in case disturbance, and nadir low enough to trigger protection relays under-frequency load shedding. existing frequency-watt function mandated inverters cannot provide grid support loss-of-generation event, PV plants...
With the growing integration of renewable power generation, plug-in electric vehicles, and other sources uncertainty, increasing stochastic continuous disturbances are brought to systems.

In proposed method, a probability measure is presented analytically solved by averaging. Compared with conventional...
In this paper, a new systematic method is proposed to analyze the system frequency in power systems under uncertain variability (UV). UV gradually increases systems, which originates from renewable energy generation, random loads, measurement, and communication channels, exerting noteworthy impacts on dynamic frequency. The modeled as stochastic process paper. Then, differential equations are used describe response (SFR) of UV, based SFR model. To assess dynamics an index intra-range...
This paper proposes a novel method to analyze impacts of uncertain variability on power system dynamics. There is considerable interest in integrating intermittent renewable energy and plug-in electric vehicles into systems. Therefore, systems are an environment with increasing variability.

Based averaging method,...
With photovoltaic generation increasing, the wide-area oscillation has a vital influence on long-distance power transmission of power. For an efficient integration generation, gain scheduling damping controller (WADC) is designed to guarantee system performance under signal delay and changing operating condition, which could be aggravated by fluctuant uncertain generation. A linear parameter-varying (LPV) model proposed represent all possible conditions within varying ranges load. Then,...
Microsphere‐assisted microscopy allows the limit of diffraction light to overcome while being non‐invasive, full‐field, label‐free, and easy‐to‐implement. However, observation translucent samples remains difficult using a classical bright‐field illumination. In this work, method is presented for inspection quasi‐transparent sub‐diffraction‐limited structures by dark‐field illumination in transmission mode. Glass‐imprint features, having size 250 nm, as well fixed mouse brain cells have been...
