To forecast and assess the impact of large-scale electric buses (EBs) to power grid, the aggregating charging load model of EBs cluster is indispensable. As EB’s typical operating, including driving and parking, is a cyclical process and has obvious regularity, a procedural simulation method for aggregating charging load model of EBs cluster based on battery swapping mode is proposed in this paper. With the data come from specific buses lines and other information readily available, the behavior process of each individual in EBs cluster is continuously simulated. Then time and SOC information of battery packs emerges and is recorded. Combined with specific charging control method, corresponding aggregating charging load model becomes available. The proposed method has been verified by simulation on an actual buses line with charging/swapping station. The results show that the proposed method can grasp characteristics of EBs cluster’s charging load under multiple factors, thereby improve the practicality and reliability of modeling.
