Distributionally robust scheduling of electric-thermal-hydrogen microgrid based on comprehensive norm

The electric-thermal-hydrogen microgrid provides a promising choice for hydrogen utilization and energy transition towards low carbon. However, the economic operation of microgrids is impeded by source uncertainties, thus, a distributionally robust scheduling model considering security constraints of hydrogen equipment is proposed. First, the electric-thermal-hydrogen microgrid structure and equipment models are established. Secondly, the economic objective function for minimizing system operating cost is proposed. Furthermore, in the first stage, constraints are introduced based on deterministic scheduling model. In the second stage, the supporting set that represents the source uncertainties is considered. Then, in order to reschedule the flexible resources, further constraints based on the comprehensive norm are introduced. Finally, the column-and-constraint generation (C&CG) algorithm is adopted to solve the proposed two-stage scheduling model. Simulation is conducted to verify the effectiveness of the proposed model. It is confirmed that the proposed scheduling model appropriately strikes a balance between robustness and economic operation.
