Embodiment Construction

[0068] The preferred embodiments are described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0069] figure 1 It is a structural diagram of the optical storage charging station used in the present invention. The operating principle of the solar-storage charging station is that photovoltaic power generation gives priority to charging electric vehicles. When the power generation exceeds the charging demand in the station, the surplus power is stored in the cascade battery energy storage system; when the power generation is insufficient, the cascade battery energy storage system provides electric vehicles required charging power. The method for configuring the capacity of an optical storage charging station provided in this embodiment includes:

Abstract

The invention relates to the technical field of optical storage and charging station capacity configuration of electric automobiles, and discloses an optical storage and charging station capacity configuration simulation modeling method considering battery cascade utilization. According to the method, on the basis of calculating the service life of a cascade battery energy storage system, the costof the cascade battery energy storage system is estimated through a double declining balance method; an optical storage capacity configuration model of an optical storage and charging station considering battery cascade utilization is established by taking the maximum annual net income of the optical storage and charging station as the target function and taking the real-time power balance of a charging station, charge state constraint of an energy storage system and the like as constraint conditions; and the model is solved by adoption of a teaching and learning algorithm, so that the optimal photovoltaic capacity and energy storage capacity are obtained.

Description

technical field [0001] The invention relates to the technical field of battery energy storage, and more specifically, relates to a simulation modeling method for optimizing the capacity of an optical storage charging station taking into account cascade utilization of batteries. Background technique [0002] With the widespread development of electric vehicles in countries around the world, the planning and construction of charging infrastructure has received more attention from the Chinese government. Since solar energy is green, clean and inexhaustible, the construction of photovoltaic charging stations for electric vehicles can effectively improve the utilization rate of clean energy, reduce dependence on fossil fuels, improve my country's primary energy structure, and increase the efficiency of energy conservation and emission reduction. However, the photovoltaic system can only meet the charging needs of electric vehicles during the day, and the grid is required to charg...
