A High Impedance Fault (HIF) in the power distribution systems remains mostly undetected by conventional protection schemes due to low fault currents. Apart from degrading reliability of supply customers, HIF can impose a high cost on utilities technical damages. The nonlinear and asymmetric nature makes its detection identification very challenging. signatures are form minute-level distortions observable AC sinusoidal voltage current waveforms but these do not follow clear pattern.

Moreover, performs online optimization, value decision...

Future power systems, in which generation will come almost entirely from variable Renewable Energy Sources (vRES), be characterized by weather-driven supply and flexible demand. In a simulation of the future Dutch system, we analyze whether there are sufficient incentives for market-driven investors to provide level security supply, considering profit-seeking myopic behavior investors. We co-simulate two agent-based models (ABM), one expansion operational time scale. The results suggest that...

Flexibility will be required as more renewable generation is integrated in the power system. Therefore, entities such Service Providers (FSPs) have emerged who can control a diverse set of resources their portfolio to provide requested flexibility. An accurate and reliable assessment amount dispatchable flexibility FSP's considering demand response activation, ramp rate, post-activation rebound effects, etc. important. In case FSP cannot fulfill request, it must known beforehand avoid...

Anticipating failures is vital for maintaining a reliable power supply. Advanced measurement devices in the grid generate vast data that contains valuable information on operations. Initial signatures of an incipient failure are often reflected this form electrical waveform distortions. Conventional protection schemes not equipped to analyze these distortions and anticipate failures. There considerable research gap simple yet robust universal anticipation diagnosis scheme.

To counter the inherent intermittent and unpre dictable power generation from large amounts of wind solar, fast-acting resources are required, one options being sector coupling via to gas devices. Industrial Power Gas (IPtG) resources, such as an electrolyzer, represent attractive solution satisfy rising energy flexibility needs renewable-rich systems. Since these electrolyzers can be asked respond quickly following steep ramps renewables, it is imperative understand their capabilities...

Acquisition of seismic data over a large 3D survey acquired in Mexico is constrained by both cultural and ecological limitations, resulting strong acquisition footprint that contaminates the target turbidite reservoir interest. Due to obstacles, source receiver grid quite irregular, such we cannot suppress through simple kx‐ky filtering time slices. In this survey, most vexing components are due leakage backscattered ground roll into migration‐stack migration artifacts. 2D Wavelet Transforms...

We present comparisons of some the available algorithms for acquisition footprint suppression. Fourier transform based Kx‐Ky filtering is very efficient noise removal, but can also remove geologic features. New wavelet transforms techniques show promising results that overcome these disadvantages. They allow decomposition seismic signal on different scales and only those have noise. The combination 1D (wavelet transform) 2D (FFT or gives best it computationally intensive. use attribute...

Renewable Energy Sources (RES), and especially wind turbines (WT) as the most mature technology, will provide a large share of energy generation in future sustainable power system.

The traditional methodology for conducting technical assessments of multi-energy systems involved using domain-specific modeling tools to focus on the energy sector interest, while making simplifying assumptions about any coupled sector. This was acceptable since interactions between domains were minimal. However, with expectation an increased adoption conversion technologies (such as power X (P2X) systems: heat, gas, etc.) in future, and consequently higher interaction various sectors...
