Description

technical field [0001] The invention relates to a method for predicting the schedulable capacity of an electric vehicle cluster, more specifically, a method for predicting the schedulable capacity of an electric vehicle cluster based on big data. Background technique [0002] Electric vehicles have advantages that traditional vehicles cannot match in terms of environmental protection, cleanliness and energy saving. Due to the great randomness of electric vehicle charging, the access of large-scale electric vehicles will have adverse effects on the power grid, including affecting the power quality of the distribution network and increasing the difficulty of control optimization. The development of Vehicle-to-grid (v2g) technology brings new opportunities for large-scale access of electric vehicles. The electric vehicle cluster connected to a certain grid area can be used as a large distributed energy storage system, which can provide various auxiliary support services for th...

Problems solved by technology

[0006] One is the use of probability model prediction method to face the problems of human factor interference and low accuracy of probability model

[0007] The second is that it does not consider multi-time scale power dispatching, and cannot meet the requirements of multi-time scale dispatching of power systems.

[0008] The third is that it does not consider that the data for the calculation and prediction of dispatchable capacity is a big data problem. In order to obtain higher prediction accuracy, the method of using the probability model also needs to conduct research on a large amount of electric vehicle charging data.
