Active power distribution network power quality evaluation method and device, terminal and storage medium

The invention relates to the technical field of power grid electric energy quality analysis, in particular to an active power distribution network electric energy quality evaluation method and device, a terminal and a storage medium. Constructing a power grid characteristic model for expressing power grid frequency disturbance characteristics according to the plurality of historical monitoring data sets and the basic model; determining a plurality of output data sets according to the plurality of historical environment data sets and the output curve; and finally inputting the plurality of output data sets, the load constraint conditions of the plurality of loads in the power grid and the output constraint condition of the main power supply into the power grid characteristic model, and determining the potential hazard of the power grid according to a plurality of output results of the power grid characteristic model. According to the embodiment of the invention, the combination of multiple load data and main p
