Abstract:

To ensure the security and stability of ice-covered power grid, the model and solution method of the collaborative optimization of de-icing outage scheduling and unit commitment are proposed. First, the constraints of de-icing outage scheduling were established, which also guarantee that the ice thickness does not exceed its designed value, then it’s co-optimized with the unit commitment. Since the proposed problem is a large-scale nonconvex and nonlinear problem which is hard to be solved directly, auxiliary variables were adopted to recast the model to a mixed integer linear optimization (MILP) problem. Then the MILP model was decoupled to the unit commitment subproblem and de-icing outage scheduling subproblem by Lagrange relaxation, which can be solved iteratively. To improve the computing speed, acceleration strategies were proposed. The proposed model was tested on IEEE RTS79 system, and the results show the validity of the proposed model and solution method. The results also show that the proposed de-icing outage scheduling can ensure the safety of ice-covered grid.
