Abstract：A new parallel algorithm for unit commitment including AC power flow constraints is proposed. This algorithm employs a new augmented Lagrange relaxation method that involves the variable duplication technique and auxiliary problem principle to convert the primal problem into its dual problem, and obtain the separation structure of the Lagrangian function which can be decoupled into dynamic programming subproblem and optimal power flow (OPF) subproblem. Predictor-corrector interior point method is applied to solve OPF subproblem. Parallel computing is used to accelerate the computational speed. The numerical results on IEEE118 and IEEE300 cases show that the proposed algorithm has good convergence performance, is very suitable for parallel processing.
