This paper presents an algorithm, for solving security constrained economic dispatch (SCED) problem with flexible AC transmission systems (FACTS) through the application of evolutionary programming (EP). The problem is decomposed into the optimal setting of FACTS parameters subproblem and the OPF with fixed FACTS parameters subproblem. These two subproblems are solved by exponential evolutionary programming (EEP). Two types of FACTS devices are used: thyristor-controlled series capacitor (TCSC) and thyristor-controlled phase shifting (TCPS). The proposed approaches have been implemented on an adapted IEEE 30 bus system and IEEE 57 bus system. The simulation results are discussed to show the performance of the EP technique and compared with newton methods. The investigation reveal that, the proposed algorithm is relatively simple, reliable, and efficient.
