Load Scheduling Approach for Energy Management and Power Quality enhancement in Glass Melting Furnaces

Although the power electronics converters involved in glass furnace boosting process may be as diverse as require the electric heating system, in tin bath and annealing lehr heating systems a thyristor based AC-AC voltage converter controlled by integral cycle control (ICC) is often employed, distributed over the multiple heating zones. The ICC is widely used due to its multiples benefits such as low transient current, increased reliability and limited harmonic distortion, but noteworthy at low frequency. The goal of this research is to establish an optimal demand response (DR) and power quality (PQ) strategy using a hybrid technique derived from ICC through a straightforward algorithm characterized by a low computational cost that provides successful results for both thermal stability as well as from the PQ and DR point of view.
