Description
The need of transition from blast furnace to electric arc furnace (EAF) steelmaking, driven by decarbonization targets and carbon regulation, is creating compounding challenges: growing furnace ratings, volatile electricity costs, degrading raw material quality, and increasing grid instability from renewable penetration. Classical technology of compensation (SVC, STATCOM) has reached its functional limits. This paper presents the Direct Feed system - a series-connected Medium Voltage solution developed by GE Vernova - which decouples EAF from the grid, delivering high flicker reduction, and grid power factor = 1 at the Point of Common Coupling (PCC), while improving EAF process KPIs through grid/EAF decoupling, arc stabilization, frequency control. The paper introduces the Medium Voltage Uninterruptible Power Supply (MV-UPS) extension - energy storage integrated directly on the Direct Feed DC bus - and demonstrates its superiority over classical shunt-connected BESS for grid ride-through, load shifting, and peak shaving applications in the EAF context.
