The requirements of the energy storage power station determine what kind of lithium battery is the most suitable energy storage battery.
In general, the purpose of the application of energy storage power station in the grid is important to consider load regulation, with new energy access, to make up for line loss, power compensation, improve power quality, isolated network operation, peak shaving and valley filling, and several other major functional applications.
For example: peak shaving and valley filling, improve the grid operating curve, to explain in layman's terms, energy storage power station is like a reservoir, you can store the surplus water during the low period of electricity consumption, and then take it out when the peak of electricity consumption, so as to reduce the waste of electricity; in addition, energy storage power station can also reduce line losses, new lines and equipment life.
What are the requirements for the selection of lithium-ion batteries for energy storage?
As a storage power plant with photovoltaic power generation access, to achieve peak shaving, load compensation, and improve power quality applications, energy storage lithium-ion is a very important component that must meet the following requirements.
1, easy to achieve multi-mode combination, to meet the higher operating voltage and larger operating current.
2, lithium iron phosphate ion battery capacity and performance of detectable and diagnosable, so that the control system can be achieved in anticipation of the battery capacity and performance of the power plant load scheduling control.
3, high safety and reliability: under normal use, the normal service life of the battery is not less than 15 years; in the limit, even if a failure occurs in the controlled range, should not occur in the explosion, combustion and other failures that endanger the safe operation of the power station.
4, good fast response and large multiplier charge and discharge capacity, generally requiring 5-10 times the charge and discharge capacity.
5, higher charge and discharge conversion efficiency, easy to install and maintain, with good environmental adaptability, a wider operating temperature range.
Lithium iron phosphate battery used in power generation systems for energy storage with good results, as a large-capacity battery storage system technology, lithium iron phosphate battery is preferred.
