The energy storage system stores the unused or surplus electric energy through a certain specification of the lithium battery pack, and then extracts and uses it at the peak of use, or transports it to a place where energy is scarce for reuse. The following is the application of lithium battery energy storage systems in household energy storage and commercial energy storage.
The home energy storage system
Home energy storage systems are currently divided into two types, one is the grid-connected home energy storage system, and the other is the off-grid home energy storage system. Home energy storage lithium battery packs allow you to obtain safe, reliable, and sustainable energy, and ultimately improve the quality of life.
Household energy storage products can be installed in household energy storage lithium battery packs, whether in photovoltaic off-grid application scenarios or even in households where photovoltaic systems are not installed.
Household energy storage lithium battery packs have a service life of more than 10 years, modular design, multiple energy storage units can be connected in parallel more flexibly, simple, fast, and greatly improve energy storage and utilization.
The grid-connected home energy storage system
It consists of five parts, including solar cell array, grid-connected inverter, BMS management system, lithium battery pack, and AC load. The system adopts a mixed power supply of photovoltaic and energy storage systems. When the mains power is normal, the photovoltaic grid-connected system and mains supply power to the load. When the utility power is cut off, the energy storage system and the photovoltaic grid-connected system are jointly powered.
The off-grid home energy storage system
This is independent and has no electrical connection with the grid, so the entire system does not need grid-connected inverters, and photovoltaic inverters can meet the requirements. The off-grid home energy storage system is divided into three working modes. The first mode is photovoltaics to provide energy storage and user electricity (sunny day). The second mode is that photovoltaic and energy storage batteries provide users with electricity (cloudy days); the third mode is that the energy storage batteries provide users with electricity (evening and rainy days).
The commercial energy storage system
Energy storage technology is closely connected with new energy applications and the development of power grids, which can effectively improve energy efficiency and solve power supply problems in remote areas. Therefore, energy storage technology is a key technology that needs to be solved when solar and wind power generation becomes the main energy source, and it is a key link that cannot be bypassed in the development of new energy.
A small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc., is currently the main application of energy storage lithium battery pack systems.
Distributed power generation has the advantages of high energy efficiency, low pollution, high reliability, and flexible installation location, but at the same time, it has disadvantages such as strong output power fluctuation and complex control. In order to effectively integrate the advantages of distributed power generation, increase the utilization rate of renewable energy, and enhance the stability of the power grid, energy storage systems have received extensive attention from the energy community.
New energy vehicle charging station
The charging station uses clean energy to supply power. After photovoltaic power generation, the electric energy is stored. The photovoltaic, energy storage and charging facilities form a micro-grid, which can intelligently interact with the public grid according to the demand and can realize two different operation modes of grid connection and off-grid.
The use of energy storage systems can also alleviate the impact of charging piles on the regional power grid during high-current charging. The development of new energy vehicles is inseparable from the construction of charging infrastructure. The installation of supporting energy storage facilities will help improve the quality of local power grids and increase the site selection of charging stations.
Wind power system
Considering the reality of grid operation and the long-term benefits of large-scale development of wind power, improving the controllability of the output power of wind farms is an important development direction of wind power technology at present. The introduction of wind power technology into the lithium battery energy storage system can effectively suppress wind power fluctuations, smooth the output voltage, improve power quality, ensure the grid-connected operation of wind power, and promote wind energy utilization.
At this stage, most of the lithium batteries used in the field of communication backup power supply are lithium iron phosphate battery packs. The backup power supply based on lithium battery packs can be widely used in indoor and blind area coverage, second and third types of city power areas, and short-term backup power. Scenarios that require high power supply weight, volume, cycle life, and magnification.
In the era of big data, scenarios with limited space such as shared stations and central computer room expansion also gradually require the participation of lithium battery backup power.
