The requirements of energy storage power stations determine what kind of lithium battery is the most suitable energy storage battery. Generally speaking, the application purpose of energy storage power stations in the power grid mainly considers several major functional applications such as load regulation, cooperating with new energy access, compensation for line loss, power compensation, and improvement of power quality. The energy storage power station is like a reservoir, which can store the surplus water during the low electricity consumption period and use it at the peak of electricity consumption, thus reducing the waste of electricity; in addition, the energy storage power station can also reduce line loss, New lines and equipment service life.
What are the requirements for the selection of energy storage lithium-ion batteries?
As an energy storage power station for load regulation and improvement of power quality applications, energy storage lithium battery is a very important component and must meet the following requirements:
1. It is easy to realize multi-mode combination to meet higher working voltage and larger working current;
2. The capacity and performance of the lithium iron phosphate battery can be detected and diagnosed so that the control system can realize the dispatch control of the power station load under the condition of predicting the battery capacity and performance;
3. High safety and reliability: In normal use, the battery's normal service life is not less than 15 years; in extreme cases, even if a failure occurs, it is still in the control range, and there should be no explosion, combustion, etc. that endanger the safe operation of the power station failure;
4. It has good fast response and large rate charge and discharge capability, generally, 5-10 times of charge and discharge capability is required;
5. Higher charge-discharge conversion efficiency, easy installation and maintenance, good environmental adaptability, and wide operating temperature range.
Lithium iron phosphate batteries have a good effect when used in power generation systems as energy storage. As technology for large-capacity battery energy storage systems, lithium iron phosphate batteries are the first choice.
