Multiple Objective Compromised Method for Power Management in Virtual Power Plants
Energies - Tập 4 Số 4 - Trang 700-716
Jinxia Gong, Da Xie, Chuanwen Jiang, Yanchi Zhang
In practical optimization, a priority requirement for different objectives of multiple objective optimization problems should be considered. In this paper, the distributed power management of a Virtual Power Plant (VPP) with priority requirement is optimized by the compromised method. The operation optimization model of VPP is formulated as a fuzzy multiple objective optimization problem c...... hiện toàn bộ
Hydrogen-Rich Syngas and Biochar Production by Non-Catalytic Valorization of Date Palm Seeds
Energies - Tập 15 Số 8 - Trang 2727
Hani Hussain Sait, Ahmad Hussain, M. Bassyouni, Imtiaz Ali, Ramesh Kanthasamy, Bamidele Victor Ayodele, Yasser Elhenawy
Pyrolysis has been demonstrated to be a highly effective thermochemical process for converting complex biomaterials into biochar and syngas rich in hydrogen. The pyrolysis of mixed date palm seeds from Saudi Arabia was conducted using a fixed-bed pyrolyzer that was custom made for the purpose. The influence of the pyrolysis temperature (200–1000 °C) on the various physicochemical parameter...... hiện toàn bộ
Extreme Quantiles Dynamic Line Rating Forecasts and Application on Network Operation
Energies - Tập 13 Số 12 - Trang 3090 - 2020
Dupin, Romain, Cavalcante, Laura, Bessa, Ricardo J., Kariniotakis, Georges, Michiorri, Andrea
This paper presents a study on dynamic line rating (DLR) forecasting procedure aimed at developing a new methodology able to forecast future ampacity values for rare and extreme events. This is motivated by the belief that to apply DLR network operators must be able to forecast their values and this must be based on conservative approaches able to guarantee the safe operation of the network.

Environmental Impacts and Costs of Hydrotreated Vegetable Oils, Transesterified Lipids and Woody BTL—A Review
Energies - Tập 4 Số 6 - Trang 845-877
Kathrin Sunde, Andreas Brekke, Birger Solberg
This article reviews and compares assessments of three biodiesel fuels: (1) transesterified lipids, (2) hydrotreated vegetable oils (HVO), and (3) woody biomass-to-liquid (BTL) Fischer-Tropsch diesel and selected feedstock options. The article attempts to rank the environmental performance and costs of fuel and feedstock combinations. Due to inter-study differences in goal and study assump...... hiện toàn bộ
Review on Deep Neural Networks Applied to Low-Frequency NILM
Energies - Tập 14 Số 9 - Trang 2390
Patrick Huber, Alberto Calatroni, Andreas Rumsch, Andrew Paice
This paper reviews non-intrusive load monitoring (NILM) approaches that employ deep neural networks to disaggregate appliances from low frequency data, i.e., data with sampling rates lower than the AC base frequency. The overall purpose of this review is, firstly, to gain an overview on the state of the research up to November 2020, and secondly, to identify worthwhile open research topics...... hiện toàn bộ
Algal Biofuels: Current Status and Key Challenges
Energies - Tập 12 Số 10 - Trang 1920
Marwa Gamal Saad, Noura S. Dosoky, M. Sh. Zoromba, Hesham M. Shafik
The current fossil fuel reserves are not sufficient to meet the increasing demand and very soon will become exhausted. Pollution, global warming, and inflated oil prices have led the quest for renewable energy sources. Algal biofuels represent a potential source of renewable energy. Algae, as the third generation feedstock, are suitable for biodiesel and bioethanol production due to their ...... hiện toàn bộ
Study of Material Compatibility for a Thermal Energy Storage System with Phase Change Material
Energies - Tập 11 Số 3 - Trang 572
Songgang Qiu, Laura Solomon, Ming Fang
The suitability of stainless steel 316L and Inconel 625 for use in a latent heat thermal energy storage (TES) system was investigated. A NaCl–NaF eutectic mixture with a melting temperature of 680 °C was used as the phase change material (PCM). Containers were filled with the PCM prior to heating to 750 °C, then examined after 100 and 2500 h of high-temperature exposure by analyzing the ma...... hiện toàn bộ
Boosting Energy Efficiency and Solar Energy inside the Residential, Commercial, and Public Services Sectors in Mexico
Energies - Tập 13 Số 21 - Trang 5601
Genice K. Grande-Acosta, Jorge Islas
The residential, commercial, and public sectors consume between 20% and 30% of final energy demand worldwide. Due to the intensive use of fossil fuels and conventional electricity, they also have an important participation in the emission of greenhouse gases (GHG). Taking Mexico as a case study, this article develops an alternative scenario that considers that in these sectors, buildings c...... hiện toàn bộ
AC Volume Breakdown and Surface Flashover of a 4% NovecTM 4710/96% CO2 Gas Mixture Compared to CO2 in Highly Nonhomogeneous Fields
Energies - Tập 13 Số 7 - Trang 1710
Houssem Eddine Nechmi, Mohammed El Amine Slama, A. Haddad, Gordon Wilson
AC pre-discharge currents, breakdown, and flashover voltage measurements are reported in a 10 mm needle-plane arrangement in a 4% NovecTM 4710/96% CO2 gas mixture and compared with CO2 for pressures up to 8.8 bar abs. Flashover measurements were performed on different solid dielectrics (Al2O3_filled epoxy resins, PTFE (Polytetrafluoroethylene) and PE (polyethylene)) for different roughness...... hiện toàn bộ
Impact of the Paleoclimate, Paleoenvironment, and Algae Bloom: Organic Matter Accumulation in the Lacustrine Lucaogou Formation of Jimsar Sag, Junggar Basin, NW China
Energies - Tập 13 Số 6 - Trang 1488
Yuhan Jiang, Dujie Hou, Hang Li, Ziming Zhang, Ruibo Guo
Shale oil exploration has been a key area of onshore oil and gas exploration in China in recent years. In this study, organic geochemistry and element geochemistry are united to study the shale oil and source rock in the Lucaogou formation of Jimusar sag, in order to reveal the paleoclimate, paleoenvironment, source of organic matter, and factors affecting organic matter accumulation and s...... hiện toàn bộ
