Abstract  To build a more precise charging load model of electric public buses, the probability distribution and sampling method of charging state and charging start time are studied. Firstly, an adaptive kernel density estimation with boundary Kernel algorithm is proposed to build probability distribution models. The proposed algorithm does not require any assumptions about the probability distribution, and can also solve the problems of boundary bias and lacking of local adaptability, which improves the precision and adaptability of probability distribution. Secondly, Latin hypercube sampling with cubic spline interpolation algorithm is proposed to figure out the inverse cumulative distribution function of probability distribution. The proposed algorithm has high precision and sampling efficiency. Finally, based on these two algorithms, electric public bus charging load model is set up. The simulation result demonstrates the effectiveness and adaptability of the proposed method.
