A MILP model concerning the optimisation of penalty factors for the short-term distribution of byproduct gases produced in the iron and steel making process

A Review of Mathematical Programming in Integrated Iron‐ and Steelmaking

“…Kong et al , proposed a similar model and its modification in 2010. In 2015, Zhao et al presented an MILP model for by‐product gas distribution with relatively short time intervals of 15 minutes and corresponding dynamic constraints. While the study's objective is cost reduction, the modelling focus lies on investigating the trade‐off between gasholder stability and flexibility.…”

How energy price changes can affect production- and supply chain planning – A case study at a pulp company

“…Marshman et al, 2010;Xiaoyan et al, 2012), or where by-products in the steel industry have been in focus (e.g. Zhao et al, 2015). In addition, the emerging bioenergy business area is believed to provide plenty of opportunities for the forest sector and its "green gold" (Pätäri et al, 2011).…”

Collaborative Scheduling between OSPPs and Gasholders in Steel Mill under Time-of-Use Power Price

“…Around 60% of the byproduct gases were used for heating in the metallurgical process, and the flexibility of the gas consumption is very limited because the regular steel production is stable [9]. On the other hand, the rest of the byproduct gases can be adjusted more flexibly, either consumed by the OSPPs or stored in gasholders.…”

“…The imbalance between the production and consumption of byproduct gases makes the overall system suffer from fluctuations, which is liable to make gas flaring necessary or negatively affect the gas supply of the boilers and CCPPs. Therefore, in previous studies, gasholder levels were preferably sustained around the middle level, since the middle level possesses the best anti-fluctuation ability [3,4,[9][10][11]. The significance of the gas storage function of the gasholder becomes obvious for the electricity cost reduction if the time-of-use (TOU) electricity tariff is considered [12][13][14].…”
