The paper describes the use of porous carbon material (PCM), obtained from plant raw materials as anode of lithium power source (LPS). It is established that the electrochemical parameters of LPS at current density of C/...

Virtual reality (VR) is one of the most common technologies nowadays, which make a virtual environment exactly similar to the real environment. The purpose behind this is to test several issues (designing or manufacturin...

Nonradiating sources of energy realized under a wave scattering on high-index dielectric nanoparticles have attracted a lot of attention in nano-optics and nanophotonics. They do not emit energy to the far-field, but si...

INTRODUCTION: High renewable energy penetration introduces significant uncertainties in distribution networks, posing challenges for source-load power forecasting and voltage management. OBJECTIVES: This study aims to e...

The article examines the regulatory mechanisms for the integration of renewable energy sources and their impact on the indicators of the state's energy security, taking into account the financial and credit conditions of...

Abstract The integration of large-scale distributed power sources complicates grid topology and intensifies spatiotemporal coupling in power data. This complicates the analysis of intrinsic correlations and makes predict...

Integration of Photovoltaic (PV) generation into oil and gas power networks has transformed fault behaviour by creating highly complex sensitivity challenges for conventional Overcurrent Relay (OCR) coordination and trip...

The increasing focus on renewable energy sources presents a viable alternative to non-renewable fossil fuels, with solar energy gaining particular attention. This research aims to identify and zone areas suitable for the...

The relevance of the topic is due to the growing role of the Eastern Mediterranean as a strategic region where the interests of global powers and regional actors intersect, which forms a complex system of interaction and...

Abstract The resilience of power grids with high share of variable renewable energy sources (VREs) is increasingly challenged by cybersecurity risks, ageing infrastructure, and inefficient asset management. These vulnera...

The integration of renewable energy sources into modern power systems is a global priority aimed at reducing carbon emissions, decreasing fossil fuel dependency, and advancing sustainable development goals. In this conte...

This paper addresses the coordinated operation between wind farms and reservoir hydropower plants in networks with weak transmission capacity. The joint operation of the energy sources is captured by a Virtual Power Plan...

The main objectives of the study are to develop a generalized thermo-electromechanical model of a solid-state heat engine based on a Ni-Ti-Cu shape memory alloy for converting low-grade thermal energy (30-100 °C) into e...

The power system event detection process must accelerate and become more precise with increasing penetration of renewable energy systems into the grid. The authors discuss a federated learning LSTM (FL-LSTM) that serves ...

The increasing penetration of renewable energy sources (RES) reduces power system inertia, causing severe frequency excursions following disturbances. Conventional Automatic Generation Control (AGC) using fixed-gain cont...

Abstract This article proposes a simple and reliable Dynamic Economic Emission Dispatch (DEED) model for a power system integrating Renewable Energy Sources (RES), including photovoltaic (PV) systems and wind energy. The...

Double-rf systems have become a standard solution in advanced storage ring light sources for beam acceleration and bunch lengthening. In this context, a compact single-cell normal-conducting bimodal rf cavity is proposed...

This article looks at the politics of coal mining in East Kalimantan in Indonesia and La Guajira in Colombia. The focus is on government power and business interests. In a Marxian theoretical framework, the study questio...

This study compares seven quantum algorithms—Variational Quantum Eigensolver (VQE), Variational Quantum Deflation (VQD), Quantum Approximate Optimization Algorithm (QAOA), Quantum Amplitude Estimation (QAE), Quant...

Abstract Cis-acting regulatory enhancer elements are powerful tools for achieving cell type-specific genetic access in adeno-associated virus (AAV) delivery platforms. However, a significant bottleneck in enhancer discov...
