Abstract

In response to issues such as power fluctuations caused by the variability of distributed renewable energy output and the uncertainty of multi-energy load consumption in distribution networks, this article proposes a planning model for electric-hydrogen charging and discharging equipment in high-proportion renewable energy distribution networks, utilizing electric-hydrogen vehicles as mobile energy storage. This model effectively addresses the optimal configuration of electric-hydrogen charging and discharging equipment under the goal of coordinating and optimizing power and energy balance in the distribution network. Firstly, based on the mobile energy storage characteristics of electric-hydrogen vehicles, a model is established that considers the spatiotemporal transfer characteristics and charging-discharging behaviors of electric-hydrogen energy storage under the constraints of traffic network topology. Secondly, considering the correspondence between the distribution network and traffic network topology, as well as the variability of renewable energy output and the characteristics of electric-hydrogen mobile energy storage, an optimization model for the configuration of charging-discharging facilities is developed, aiming to minimize the operational costs of both the charging-discharging facilities and the distribution network, along with a corresponding solving algorithm. Finally, a simulation model for the optimal configuration of electric-hydrogen charging-discharging facilities is established based on the distribution network framework of a certain area in Liaoning, verifying the effectiveness of the proposed optimization method in enhancing the multi-energy power and energy balancing capabilities of the distribution network, as well as the reliability of charging and discharging.
