Description

Technical Field

[0001] The present invention relates to the technical field of electric energy storage systems, and in particular to a photovoltaic storage charging and discharging green electric energy management system and method. Background Art

[0002] The concept of photovoltaic storage charging and discharging refers to the use of a "combination" of distributed photovoltaics, energy storage systems, and charging and discharging. Through an integrated solution, it integrates photovoltaic power generation, energy storage, microgrid control, and electric vehicle charging. It uses battery energy storage systems to absorb valley electricity and support fast charging loads during peak periods. At the same time, it is supplemented by photovoltaic power generation systems to effectively reduce the peak load of the charging station grid, improve the system operation efficiency, and provide auxiliary service functions for the grid. This model can well make up for the pain points and shortcomings in the construction of charging stations, and thus have a profound impact on the development of the new energy vehicle industry. The photovoltaic storage charging and discharging system can also solve the problem of insufficient land resources or grid access. It has the characteristics of multiple energy complementarity, large centralized land area, strong acceptance capacity, and high power utilization. The emergence of this integrated system is to solve the problem of low electricity consumption. The photovoltaic storage charging and discharging integrated station can charge itself or electric vehicles. At the peak of electricity consumption, when the power grid is insufficient, the photovoltaic storage charging integrated station can supply power to the grid, playing the role of peak shaving and valley filling. The photovoltaic storage charging industry refers to an industry with light, electricity and energy storage technology as the core, and aims to improve energy utilization efficiency and promote the development of clean energy. The development of the photovoltaic storage charging and discharging industry can promote the popularization and application of clean energy, reduce dependence on traditional fossil energy, reduce carbon emissions, and promote sustainable development. At the same time, the photovoltaic storage charging and discharging industry also has broad market prospects and economic value. The current photovoltaic storage charging and discharging energy management is based on artificially set time periods to control the energy storage equipment to charge or discharge the power grid system, which is easy to cause the power load of the power grid system to overload, and cannot intelligently decide the charging or discharging behavior of the energy storage equipment to the power grid system based on the power load status of the power grid system, which reduces the applicability and safety of the photovoltaic storage charging and discharging energy management system.

[0003] The Chinese invention patent application with publication number CN112165108A discloses a green backup power supply system and method for a data center, which takes hydrogen energy storage as the core, and applies fuel cell power generation technology, electrolytic cell hydrogen production technology and lithium battery energy storage technology to realize the backup power supply function of the data center and cooperate with the auxiliary peak-shaving function of the power grid. The configured lithium battery unit effectively improves the response speed of the green backup power supply of the data center. According to the working requirements of the green backup power supply of the data center, four typical operating modes are divided, namely, the backup power supply mode, the auxiliary peak-shaving mode, the lithium battery charging mode and the hydrogen production mode, and the converter structure and operating technology of each unit under each mode are designed. In addition, an energy management system is designed, and a working mode judgment process of the energy management system is proposed, and the entry conditions of each operating mode are specifically analyzed. Through the online energy regulation of the energy management system, the coordinated operation of the backup power supply and the power grid is finally realized. The above technical scheme cannot make intelligent decisions on the charging or discharging behavior of the power grid system based on the power load state of the power grid system, which reduces the applicability and safety of the green backup power supply system.
