    Abstract

    There have been observed several voltage instability phenomena in electric power systems where receiving end voltages oscillate or get much lower than the nominal values. Such phenomena tend to occur in heavy loaded conditions and seem to be related to the multiple load flow solution problem. It is hard to solve the voltage instability problem at a stretch since dynamic factors get involved in this problem and thus a high dimentional and multi-parameter system has to be dealt with. This paper proposes a sequence of criteria which are applied to the individual members of a solution pair of the load flow to see their difference in behavior. The relationship between voltage instability and closely-located solution pair is analyzed from various viewpoints for power systems of different types and sizes.
