Abstract: An algorithm to solve unit commitment problem (UCP) with operational, power flow and environmental constraints under contingencies has been developed to plan an economic and secure generation schedule. The unit commitment (UC) solution for the environmental constrained problem has been formulated as a multi-objective problem by considering both Economic load dispatch (ELD) and Economic emission dispatch (EED) simultaneously. The combined economic emission dispatch (CEED) bi-objective problem is converted to single objective function by adding a modified price penalty factor. The UCP solutions without operational and power flow constraints are not practical due to secure operation of the power system network. This proposed algorithm introduces an efficient UC approach that obtains the minimum operating cost satisfying both unit and network constraints when contingencies are included. Repeated OPF for the satisfactory unit combinations for every line removal under th!
e given study period has been carried out to obtain UC solutions with both operational, power flow and environmental constraints. This proposed algorithm has been tested on IEEE 14, 30, 57, 118 buses and practical Indian utility systems. The solutions obtained are quite encouraging and useful in the economic emission environment. The algorithm and simulation are carried through Matlab environment.
