An algorithm is described that can be used in analyzing reactive power flow contingencies. The algorithm is accurate, fast, and easy to implement. This approach uses MW distribution factors in conjunction with newly developed volt-ampere reactive (VAr) distribution factors to solve for the postcontingency bus voltage magnitude changes of an interconnected EHV system. A prototype version of the algorithm described in this paper is presently being tested at the Pennsylvania-New Jersey-Maryland (PJM) Interconnection Office
