A Novel Unit Commitment Approach Considering Transmission Constraints

This paper introduces a novel approach for generation scheduling of power systems with transmission line limits consideration. The new method decomposes the solution of the transmission constrained unit commitment problem into hvo subproblems. In the first subproblem the uadratic cost function of units linearized and hourly optimum solution of UC is obtained. Then, all of UC problem constraints are satisfied except transmission line power limits. A new mixed integer formulation for subproblem two is presented here. The results of this subproblem must be returned into subproblem one for satisljling unit constraints, ifneeded. The six-bus system with units is analyzed to exhibit the effectiveness of the proposed approach.
