    Abstract: Based on the measurement and statistics of a large number of relevant data of electric bus, the quantitative analysis and data simplification of the driving and charging rules are carried out. According to the information of battery capacity, driving distance and environmental conditions, the charging power model and calculation method based on data simplification are constructed. Based on the simplified data information and related calculation model, the optimized Monte Carlo method is used to predict the charging load of electric buses in a city, and the error of the forecasting load with different duration and its causes are analyzed. The accuracy and feasibility of the method are verified. The simplified processing of the data can effectively improve the operability of the prediction method, and the prediction result can meet the requirements of the charging facility planning construction and the grid operation planning.
    Key words: electric bus; driving rules; charging load forecasting; Monte Carlo method; data simplification
