An MILP approach for detailed scheduling of oil depots along a multi-product pipeline

open access: yesPetroleum Science, 2017
Oil depots along products pipelines are important components of the pipeline transportation system and down-stream markets. The operating costs of oil depots account for a large proportion of the total system’s operating costs.

Short-Term Electrical Load Forecasting Based on VMD and GRU-TCN Hybrid Network

open access: yesApplied Sciences, 2022
With the continuous increase in user-side flexible controllable resources connected into a distribution system, the components of electrical load become too diverse and difficult to be accuracy forecasted.

Dynamic Equivalent Modeling of a Grid-Tied Microgrid Based on Characteristic Model and Measurement Data

open access: yesEnergies, 2017
Microgrids can significantly improve the utilization of distributed generation (DG) and the reliability of the power supply. However, in the grid-tied operational mode, the interaction between the microgrid and the distribution network cannot be ignored.

A precise ultra high frequency partial discharge location method for switchgear based on received signal strength ranging

open access: yesInternational Journal of Distributed Sensor Networks, 2020
Partial discharges are the main insulation defects encountered in gas-insulated switchgears. When it occurs inside the gas-insulated switchgear cavity, it degrades insulation, and, sooner or later, causes a breakdown.

SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]

open access: yesInternational Journal of Quantum Information, 2008
Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.

Fundamental limits on key rates in device-independent quantum key distribution [PDF]

open access: yes, 2020
In this paper, we introduce intrinsic non-locality as a quantifier for Bell non-locality, and we prove that it satisfies certain desirable properties such as faithfulness, convexity, and monotonicity under local operations and shared randomness.
