An Efficient Mathematical Model for Distribution System Reconfiguration Using AMPL

open access: yesIEEE Access, 2021
Distribution network is an essential part of electric power system, which however has higher power losses than transmission system. Distribution losses directly affect the operational cost of the system.

Research Advances in Graphene Oxide-Based Adsorbents for Mycotoxin Decontamination in Foods [PDF]

open access: yesShipin Kexue
Mycotoxins widely contaminate foods, posing a serious threat to both the economy and human health, being a major food safety concern. Physical adsorption is a highly promising detoxification strategy, but traditional adsorbents have limited performance ...

Separation control with endwall corner jet in a high-speed compressor cascade

open access: yesJournal of Thermal Science and Technology, 2017
The influences of the endwall corner jet (ECJ) with different locations, yaw angles and jet-to-inflow total pressure ratios on the aerodynamic performance of a high-speed compressor cascade are parametrically investigated by numerical simulation.

Hazard Analysis of Traditional Post-Harvest Operation Methods and the Loss Reduction Effect Based on Five Time (5T) Management: The Case of Rice in Jilin Province, China

open access: yesAgriculture, 2021
Traditional post-harvest operation methods applied in rice fields lack advanced management knowledge and technology, which has led to post-harvest losses. We proposed the concept of Five Time (5T) management for the first time.

Modelling of hydrological response to climate change in glacierized Central Asian catchments [PDF]

open access: yes, 2007
The arid lowlands of Central Asia are highly dependent on the water supplied by the Tien Shan mountains. Snow and ice storage make large contributions to current runoff, particularly in summer.

Shapley Value-Based Techno-Economic Framework for Harmonic and Loss Mitigation

open access: yesIEEE Access, 2019
This study presents a multi-objective policy for harmonic distortion and loss mitigation in micro-grid and active distribution grid. The implementation of this policy in networks including Distributed Generation (DG), is put forward based on the ...

A Loss Reduction Optimization Method for Distribution Network Based on Combined Power Loss Reduction Strategy [PDF]

open access: yesComplexity, 2021
Power loss reflects the effective utilization rate of energy and the management level of power grids. In this paper, we propose a combined power loss reduction strategy optimization framework to improve the power loss reduction effect in a distribution network.
