SecurityConstrained Unit Commitment

This chapter presents a new approach to solve the transmission and voltage security constrained unit commitment (SCUC) problem in a restructured market structure using linear sensitivity factors and Benders decomposition. The inclusion of n-1 contingency constraints in unit commitment ensures the security of the system. The tests on a 3-bus system show the effectiveness of the proposed approach. This chapter also presents formulation considering operating conditions uncertainties (including equipment outages and load variations) and an efficient algorithm. The example of a 3-bus system illustrates the solution procedure.
