The use of energy methods in an online environment to aid in the assessment of system voltage stability is discussed. A fast algorithm is presented for determining the low voltage power flow solutions with lowest associated energy measures. The use of these measures to assess voltage security is discussed for use both online and in contingency analysis. The technique is demonstrated on a 415-bus system
