The invention relates to a new energy bearing capacity constraint scene screening method, device and equipment based on scene focusing. The method comprises the following steps: focusing according to a search rule to obtain M operation parameter samples of a power grid daily operation scene with safety and stability constraints; extracting N candidate operation points from the M operation parameter samples according to different time period operation modes of a power grid daily operation scene; screening the N candidate operation points according to a screening rule to obtain no more than L key operation points; and obtaining an operation point scene corresponding to each key operation point as a constraint scene of new energy bearing capacity index evaluation. According to the method, operation parameter samples with safety and stability constraints are obtained in a search rule focusing mode, candidate operation points are extracted from the operation parameter samples, key operation points with safety and
