Abstract

The invention discloses an equipment capacity configuration method and device for a light-hydrogen storage comprehensive charging station. The method comprises the following steps: establishing a comprehensive charging station system model which can provide services for an electric vehicle and a hydrogen fuel electric vehicle at the same time and comprises a photovoltaic system, an energy storage battery system and a hydrogen energy storage system; according to the comprehensive charging station system model, an energy flow strategy of the comprehensive charging station is determined based on the energy flow cooperation relationship among the devices of the comprehensive charging station; according to the energy flow strategy, based on the energy balance constraint, the element constraint and the power grid power supply power constraint, an equipment capacity configuration optimization model taking the annual operation cost and the autonomous operation capability of the comprehensive charging station as the target is established; and solving the equipment capacity configuration optimization model by adopting an NSGA-II algorithm and fuzzy comprehensive evaluation, and determining a capacity configuration scheme of the comprehensive charging station equipment. According to the invention, the autonomous operation capability of the comprehensive charging station is improved, and reference can be provided for optimization of charging station equipment.

Description

technical field [0001] The invention relates to the configuration optimization of charging station equipment, in particular to a method and device for configuring the equipment capacity of a solar hydrogen storage comprehensive charging station. Background technique [0002] With the rapid development of new energy vehicles, charging facilities that provide services have also received attention. Since the grid power purchase of the charging station also indirectly causes high carbon emissions, the charging station considering the combination of distributed renewable energy has a bright future. Although renewable energy provides us with convenience, they also have some disadvantages. Due to the randomness of output, they are difficult to be fully utilized. How to combine it with charging stations to achieve local consumption, reduce the impact on the power grid, and ease the pressure of power grid upgrades are problems that need to be solved.
