Hierarchical Distributed Dispatch for AC/DC Hybrid System Considering Wind Power Uncertainty

To deal with the day-ahead dispatch problem of energy and reserve resources in multi-area AC/DC hybrid systems, this paper proposes a hierarchical distributed dispatch method for AC/DC hybrid system considering wind power uncertainty. Firstly, a decomposition method for AC/DC hybrid systems is designed, and the two-stage regional robust dispatch model considering wind power output uncertainty is constructed. Then, analytical target cascading (ATC) is adopted to achieve distributed solution for multi-area unit commitment and tie-line scheduling, and column and constraint generation algorithm is employed to solve the two-stage robust optimization problem. Case study validates the effectiveness of dispatch schedules and computation performance of the proposed method.
