本发明属于电化学储能应用技术领域，具体涉及一种基于光伏发电自供电仓式储能系统。The invention belongs to the technical field of electrochemical energy storage application, and in particular relates to a self-powered warehouse-type energy storage system based on photovoltaic power generation.
背景技术Background technique
储能系统以减少弃风弃光提高新能源利用率抓手，以调峰调频提高电网运行经济性、安全性为依托，以储能与新能源互补、储能与电网调峰调频紧密互动，电能互联互通为目标的储能系统商业化应用，得到政府和业界的青睐和支持，储能系统广泛应用在调峰调频、削峰填谷、平抑新能源波动、电力应急、电网稳定调控等，然而储能系统的广泛应用也面临着诸多的技术问题和应用挑战，特别是要解决安全运行、高效运行的技术。The energy storage system is based on reducing the abandonment of wind and solar energy and improving the utilization rate of new energy, relying on peak regulation and frequency regulation to improve the economy and safety of power grid operation, complementing energy storage and new energy, and close interaction between energy storage and grid peak regulation and frequency regulation. The commercial application of energy storage systems with the goal of power interconnection has been favored and supported by the government and the industry. However, the wide application of energy storage systems also faces many technical problems and application challenges, especially to solve the technology of safe and efficient operation.
为了使储能系统安全运行，储能系统安装在专门的储能箱室即常见的保温专用集装箱中，也称为仓式储能系统，并配置了电池管理系统BMS、储能箱室温控系统、储能箱室消防系统、储能箱室照明系统、储能箱室远程监控系统，大大提高了储能系统运行的安全性。同时也产生了不少问题，如：自耗电较大，一般大于储能系统供电能力的百分之十左右或更多，而且自用电通常取自电网电力并且一般都没有电价优惠；再如，由于仓式储能系统通常放置在露天，晴天太阳的暴晒使得安装蓄电池的集装箱顶部保温层被晒透，集装箱内温度上升，对此需要更大规模的温控系统和更多的耗电，也给蓄电池安全运行增加了隐患。In order to ensure the safe operation of the energy storage system, the energy storage system is installed in a special energy storage box room, that is, a common thermal insulation container, also known as a warehouse-type energy storage system, and is equipped with a battery management system BMS and an energy storage box room temperature control. The system, the fire protection system of the energy storage box room, the lighting system of the energy storage box room, and the remote monitoring system of the energy storage box room greatly improve the safety of the operation of the energy storage system. At the same time, many problems have also arisen, such as: self-consumption of electricity is relatively large, generally greater than about 10% or more of the power supply capacity of the energy storage system, and self-consumption electricity is usually obtained from grid power and generally does not have electricity price concessions; For example, since the warehouse-type energy storage system is usually placed in the open air, the exposure of the sun on a sunny day makes the top insulation layer of the container installed with the battery penetrated, and the temperature inside the container rises, which requires a larger-scale temperature control system and more power consumption. , but also increase the hidden danger to the safe operation of the battery.
