Abstract

Electricity-intensive process industries are seeking for new ways to achieve savings on energy costs, taking advantage of the liberalization of electrical markets and integration of distributed generation. Also, the increasing share of renewables requires the grid to adapt to varying electricity availability and consumption patterns. Optimal production scheduling of power-intensive steel making processes with regard to energy cost may lead to significant savings in the electricity bill. For the purpose of this research the steel plant melt shop ...
