Microgrid Feasible Domain Construction Based on Redundancy Constraint Identification

The traditional inter-area cooperative scheduling method needs to collect all the parameter information of power-side and load-side equipment and carry out optimal scheduling according to the dispatch centre, which puts forward high requirements on the computation and storage capacity of the dispatch centre. Therefore, the aggregation of lower-level grid resources as a whole to participate in the main grid optimisation scheduling can effectively reduce the calculation scale. Based on this, this paper proposes a microgrid resource aggregation method based on feasible domain projection, and at the same time introduces a redundant constraint identification method (RCIM) to identify effective constraints. Example results show that the proposed method can effectively reduce the size of the microgrid, thereby reducing the amount of information interaction between the microgrid and the distribution network, and improving the operating efficiency of the power system.
