Electricity storage container

Technical Field

The utility model relates to an electricity storage container technical field especially relates to an electricity storage container.

Background

With the rapid development of social economy, the power load (including production power load and domestic power load) is increasing, and the fluctuation of the power load is increasing, so that huge load pressure is brought to a power grid, and the load pressure is mainly reflected in the aspect of power consumption peak-valley difference. At present, the main tasks that are undertaken in the power grid are coal power stations, oil power stations, hydroelectric power stations (for example, hydroelectric power stations with regulating properties) and pumped storage power stations. Among these power stations, pumped storage power stations serve as main power peak shaving power sources of the power grid to undertake the task of power grid peak shaving. The water pumping and energy storage technology is the most widely applied energy storage technology in the global electric energy department, and particularly, the water pumping and energy storage technology pumps water from a water storage reservoir by utilizing redundant electric energy in a low electric energy demand period, and then the water in the water storage reservoir generates electricity through a hydroelectric turbine in a high electric energy demand period, so that the effects of load balancing and electric energy arbitrage are achieved. On the basis of hydroelectric power generation of the traditional concept, the water pumping energy storage technology is a mature technology suitable for application at high power level and long discharge period, is also the most widely used energy storage form in the global electric energy power grid, and is mainly applied to energy management, frequency control and storage provision.

However, the pumped storage power station, which is one of the main peak shaving power sources of the power grid, has the following disadvantages: the land occupation is large, the construction period is long, the cost is high, and site selection and construction are influenced by geographical conditions and the development is limited to a certain extent. In addition, the huge increase of the pumping energy storage capacity is also limited by the residual cost effect and the scarcity of the environment bearable sites. Such pumped-storage power stations are not only inconvenient, but are often too bulky to be suitable for distributed power generation applications. In addition, although station room type battery energy storage power stations are built in China at present, the station room type battery energy storage power stations adopt a centralized construction mode, and the on-site adjustment of power loads is difficult to realize.
