Description

technical field

[0001] The invention belongs to the technical field of power system measurement, and in particular relates to a power system online load analysis and modeling system and method. Background technique

[0002] With the continuous development of the scale of the power grid, a high proportion of new energy grid connection, a high proportion of power electronic devices, and a high proportion of new loads have increased the complexity of the load, not only changing the power characteristics of the load, but also changing the electrical parameters of the load. The effects of demand-side response in the electricity market and charging and discharging of electric vehicles affect the original distribution characteristics of the load. The load model of "one-time modeling, long-term use" cannot accurately reflect the change of load characteristics. Therefore, it is necessary to carry out online load modeling to improve the timeliness of the model.
