REDUCING CLUSTER SIZE FOR COMPUTING REMEDIAL ADJUSTMENTS FOR VOLTAGE AND LOADING VIOLATIONS ON THE POWER SYSTEM. Conference Paper uri icon

abstract

  • A technique was earlier proposed by the authors (1983, 1984) for solving sectional outbreaks of voltage and overload violations on large electric power transmission systems by finding relatively small size clusters of controls and violated, as well as nonviolated, network elements to which they react sensitively. Because the clusters are as much as two orders of magnitude smaller than the entire system, immense savings of computation are possible. Unfortunately, the size of the clusters cannot be well regulated a priori, so there is a possibility for oversize clusters. An effective algorithm is introduced for splitting up such undesirably large clusters by inactivating a few well-chosen controls. It was necessary to use some new results in graph theory to develop the new algorithm.
