Power delivery has become more dissimilar with that of the previous era. Conventional power and energy materials, such as relic fuels, nuclear power, and renewable energy (solar power, geothermal, hydroelectric, wind power, and biomass), are already present. The energy network operation becomes complicated because the integration of power generation, energy conversion, power transportation, and power utilization should be considered. There is an intricate assignment for us to perform swift power transmission for the extremely urgent situations. These situations are the results of regional lack of energy that needs to be brought back as soon as possible. Advanced supercomputing has already been one of the powerful solutions to work out these issues. This chapter initially presents an introduction of some of the supercomputing techniques and then the potential applications and demonstration examples follow to give the readers some hint on the handling of energy network operation.
