摘要
Mobile energy storage spatially and temporally transports electric energy and has flexible dispatching, and it has the potential to improve the reliability of distribution networks. In this paper, we studied the reliability assessment of the distribution network with power exchange from mobile energy storage units, considering the coupling differences among different time and zones of the vehicle-road-network system. First, we constructed a basic mobile energy storage operation framework that supports the distribution network reliability. Next, we proposed a quantitative model to describe the dynamic zonal coupled vehicle-road-network system. Based on this model, the corresponding charging and discharging scheduling strategies for different mobile energy storage units are well designed to improve the efficiency of power support. Then, we provided a distribution network reliability assessment algorithm handling the power exchange from mobile energy storage units. Finally, we used the IEEE 33-node example system to clarify the necessity of the vehicle-road-network model in accounting for dynamic zonal coupling. We also analyzed the impact of different characteristics of mobile energy storage on the reliability of the distribution network, and verified that one can improve the distribution network reliability by increasing the response speed, power capacity, or charging/discharging power of mobile energy storage vehicles.
