Security-constrained optimal power flow (SCOPF) is becoming increasingly important in the new deregulated environment of electric power systems. This paper focuses on the development of an integrated approach to linear-programming-based (LP-based) solution of SCOPF. The power flow model includes bus voltage magnitudes and line power and reactive power flow directly in the formulation. This permits greater flexibility in incorporating voltage and line flow constraints. A six-bus system example illustrates the method. The results obtained show the power of the new approach.
