The requirements of the energy storage power station determine what kind of lithium battery is the most suitable energy storage battery.
Generally speaking, the application purpose of energy storage power station in the power grid mainly considers several major functional applications such as load regulation, cooperating with new energy access, making up for line losses, power compensation, improving power quality, isolated grid operation, peak shaving and valley filling.
For example: shaving peaks and filling valleys, improving the power grid operation curve. To put it simply, the energy storage power station is like a reservoir, which can store the surplus water during the trough period of electricity consumption and use it again when the electricity consumption peaks, thus reducing the waste of electric energy. In addition, the energy storage power station can reduce line losses and increase the service life of lines and equipment.
What are the requirements for the selection of energy storage lithium-ion batteries?
As an energy storage power station that cooperates with photovoltaic power generation to realize peak shaving and valley filling, load compensation, and improve power quality application, energy storage lithium battery is a very important component, and must meet the following requirements:
- It is easy to realize multi-mode combination to meet higher working voltage and larger working current;
- The capacity and performance of theLiFePO4battery can be detected and diagnosed, so that the control system can realize the dispatching control of the power station load under the condition of predicting the battery capacity and performance;
- High safety and reliability: Under normal use, the normal service life of the battery is not less than 15 years. In extreme cases, even if a fault occurs, it is still in the controlled range, and there should be no explosion, combustion and other faults that endanger the safe operation of the power station;
- It has good fast response and high rate charge and discharge capacity, generally requiring 5-10 times the charge and discharge capacity;
- High charge-discharge conversion efficiency, easy installation and maintenance, good environmental adaptability, and wide operating temperature range.
LiFePO4 battery have a good effect in power generation systems for energy storage. As a technology for large-capacity battery energy storage systems, it is the first choice.
