Abstract

Efficient methods are needed to evaluating discrete shunt control actions required for maintaining acceptable voltage levels following changes in loads and after network contingencies. Evaluating all possible shunt combinations would involve an excessive amount of computation. An algorithm has been developed to restrict the cases considered so that optimization is done on a subset of discrete shunt combinations. Results are presented for voltage control following changes in load level and after contingencies. A method is proposed to restrict the number of discrete shunt combinations to be considered after changes in load or following network contingencies. The emphasis in on real-time calculations. Optimization is done on a subset of discrete shunt combinations to minimize voltage deviations from desired values, the number of shunt switching events, and power system losses.
