Unit commitment with bidirectional ramping constraints of flexibility retrofit thermal power unit

International Journal of Electrical Power & Energy Systems
Flexibility retrofits of thermal power units have been widely implemented to improve power system balancing. These retrofits enable operation below the regular minimum output, known as deep peak regulation, to accommodate increasing renewable energy integration.

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Impacts of variable renewable energy on wholesale markets and generating assets in the United States: A review of expectations and evidence [PDF]

, 2020
We synthesize available literature, data, and analysis on the degree to which growth in variable renewable energy (VRE) has impacted or might in the future impact bulk power system assets, pricing, and costs in the United States.

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

Advanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Joint Peak Shaving Energy Consumption Optimization Model and Simulation Analysis of Pumped Storage Power Unit and Coal-fired Power Units

Chemical Engineering Transactions, 2016
The regional power grid is mainly a thermal power system, so it is hard to meet increasing the need of difference between peak and valley loads and the demand of peak-load regulation.
