Abstract

The electric arc furnace is an important smelting equipment in modern iron and steel enterprises. However, the load of electric arc furnace is a typical impactive and nonlinear load, and it has a huge effect on power system, electrical equipment and enterprise production. Based on the theory of peak load shifting in power system, a new load leveling strategy called time-sharing operation is proposed, which can be used to stabilize the loads of electric arc furnaces. The active power curve of single electric arc furnace is given, and the load leveling model of multiple electric arc furnaces is built, then a new GA-PSO hybrid algorithm is adopted to solve the model. Two examples of five same and different electric arc furnaces are optimized respectively, and their load fluctuations of synchronous operation and time-sharing operation are analyzed contrastively. The results indicate that the time-sharing operation strategy is effective in load leveling.
