Urban underground pipe gallery energy storage system

Abstract

The invention relates to an urban underground pipe gallery energy storage system. The system is arranged in an urban underground comprehensive pipe gallery and comprises a battery energy storage system and a heat storage system. The battery energy storage system is used for obtaining electric energy from a power grid, storing the electric energy and providing a terminal user or the power grid withthe electric energy when the terminal user needs the electric energy or the power grid needs the electric energy. The heat storage system is used for obtaining heat in the charging and discharging process of the battery energy storage system from the battery energy storage system and providing the terminal user with the heat energy when the terminal user needs the heat energy. According to the urban underground pipe gallery energy storage system, the battery energy storage system is arranged in the space of the urban underground pipe gallery, peak load shifting is conducted on a power grid, the system can serve as a backup power supply of urban key departments, and urban power utilization reliability is guaranteed; and meanwhile, the heat storage system is further arranged and used for collecting heat in the charging and discharging process of the battery energy storage system and providing users around the system with the heat.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to an energy storage system for an urban underground pipe gallery. Background technique [0002] The urban underground pipe gallery is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, and implementing unified planning , Unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. The construction of the urban underground pipe gallery avoids the impact and interference on traffic and residents’ travel due to the frequent excavation of roads for the laying and maintenance of underground pipelines, and keeps the road capacity intact and beautiful; reduces the cost of multiple renovations of the road surface ...
