Performance Assessment for Automatic Generation Control via Dynamic Models Identified From Extracted Data Segments

open access: yesEnergy Science &Engineering, EarlyView.
For the automatic generation control (AGC) systems, not all data segments are suitable for performance assessment and severe noises induce uncertainties in the estimates of performance metrics. For the first challenge, the proposed method extracts step‐pattern data segments, from which dynamic models are identified and performance metrics are estimated

In situ X‐ray diffraction studies on the production process of rhenium

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022
Abstract Rhenium powder is industrially produced in a two‐step reaction by reducing NH4ReO4 with hydrogen at 623 and 1173 K. In this study, both steps of the production process have been investigated via in situ X‐ray powder diffraction. Up to 550 K no reaction with hydrogen can be observed. Between 550 K and 623 K poorly crystalline rhenium is formed.

An Environmental‐Economic Analysis of a Case Solar Power Plant for Power Decarbonization

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT On the path to achieving net‐zero emissions targets by 2050 and meeting the increasing electricity demand, investigations on the carbon intensity of electricity is of interest as an important decision‐making parameter in decarbonizing the power sector and replacing nonrenewable power plants in regions of low rainfall and limited water ...

Use of virtual reality to engage undergraduate students in environmental field experiences

open access: yesFuture in Educational Research, EarlyView.
Abstract Field‐based experiences enhance cognitive and affective skill sets of undergraduate students. Although field‐based learning is a highly effective pedagogical modality, it is not accessible to all students, necessitating the development and evaluation of alternate modalities that convey equivalent benefits.
