Abstract:
1. A method of assessing a condition of an electrical power system including a network of buses, at least certain of the buses including a respective reactive source, the method comprising: (I) performing a plurality of contingencies using a mathematical model of the network manipulated by a processor; (II) determining a representative solution for each contingency of the plurality of contingencies; (III) for each bus in the network, tabulating symptoms of system stress exhibited by the bus in the representative solution for each contingency; (IV) categorizing each contingency into one of at least two contingency clusters based on its representative solution; (V) sorting those of the buses having a highest number of the symptoms of system stress summed over those contingencies categorized within a respective contingency cluster into a respective bus group associated with the respective contingency cluster; (VI) arranging each of the at least two contingency clusters into a ranking based on its effect on the network; and (VII) selecting a location for a network enhancement from a group of buses associated with a contingency cluster of the ranking that has a largest effect on the network and also includes buses as a result of the sorting.
