An integrated process facility recently went through an update of its existing load shedding scheme due to planned changes in the processes in the coming years. Transient simulations indicated that, by changing the load shedding philosophy, the frequency profile during power shortages could be improved significantly. This paper discusses the plant's electrical/steam load balance issues and the development of a high-speed load shedding scheme.
