Optimized dispatching method and system for net load admissible domain of power system

The invention discloses a power system net load acceptable domain optimization scheduling method and system, and the method comprises the steps: converting a pre-constructed power system net load acceptable domain optimization scheduling model based on a new affine strategy and a dual theory, and obtaining a linear programming model; solving the linear programming model by adopting a solver to obtain an optimized scheduling scheme; wherein the power system net load acceptable domain optimization scheduling model is constructed based on the influence of the power system on the acceptance capability of node net load disturbance by defining a net load acceptable domain as a gap which needs to be decided. According to the invention, the net load admissible domain is defined as a gap needing decision to replace an uncertain set introduced by a traditional information gap decision theory, the influence of the system on the admission ability of node net load disturbance is researched, and a more comprehensive and re
