Two-stage robust optimal scheduling of distribution network of wind power hydrogen power station with wind power dependency

Integrating hydrogen storage systems into distributed wind power distribution grids has significant application potential. This paper considers the correlation between the outputs of different wind power plants and uses the minimum volume enclosing ellipsoid (MVEE) algorithm to establish a high-dimensional ellipsoid set to describe uncertain parameters. The conservatism of the uncertain set is corrected by the correction coefficient. A robust optimization model for an active distribution grid with wind power-based hydrogen production system considering wind power correlation is proposed. Finally, based on the strong duality theory and the column and constraint generation (C&CG) algorithm, the model is solved by alternating iterative computation. The validity of the proposed model and method is verified on the improved IEEE 33-node system.
