Abstract:

For the operation modeling and simulation of distribution networks containing energy storage systems, traditional methods lack additional constraints on energy storage system variables, resulting in a high network loss rate of the modeled system. Therefore, a method for establishing a power grid operation model and conducting distributed simulation research, an energy reserve system that includes batteries with charging and discharging performance, is proposed in the thermal storage contact technology. Based on the operational characteristics of the energy storage system in the distribution network, an equivalent circuit for energy storage is established, and a power grid operation model is constructed with the minimum network loss of the energy storage system. At the same time, variable supplementary constraints are added to it to dynamically describe the operation process of the distribution network. The results show that the designed algorithm can improve the stability of energy storage systems, reduce operating costs, and achieve better and better shading effects.
