Why Do We Need Industrial And Commercial Storage

1. The transformer design capacity is insufficient, can not support the gradually increasing load demand, overload leads to safety problems.
2. In unstable areas of the power grid, instead of diesel power generation to establish network support, short-term or long-term support within the network load operation.
3. Hospitals, base stations and other scenes have sensitive loads, high requirements for power supply stability. The unstable power supply of the grid, the over-limit voltage, and the poor power quality will cause damage to the equipment.
4. Industrial and commercial parks hope to reduce carbon emissions and achieve low carbon production or even zero carbon production by adding light storage systems

At the beginning of the construction of the plant, the distribution transformer usually has a partial margin on the basis of meeting the planned load. However, the growth rate of load is usually difficult to predict, whether it is an increase in production load or an increase in office load, it may lead to transformer overload in the short term.
For the scenario of insufficient transformer capacity, high load rate and difficult expansion, an energy storage system can be configured to alleviate this situation.
In this case, the transformer overload time is usually short, and the peak load only exists for a short time, in a few minutes to tens of minutes. During this time, the transformer will be in an overload state, increasing the risk of electricity consumption. However, if it is only for the capacity of this ten minutes, the cost of transformer capacity increase is higher, and the transformer transformation and capacity increase time is longer, and the shutdown of the production load will bring higher losses to the factory.
This situation can be fully reduced by adding an energy storage system to relieve the electricity pressure during the peak load period. The way of adding energy storage, construction is simpler, and cost-effective. However, in this way, it is usually impossible to measure the economic value of its allocation and storage, more or practical value.

The second scenario is mainly based on the combination of firewood and energy storage. At this stage, the scene is mainly concentrated in non-grid or weak grid areas, such as mining areas, border posts, islands and other scenes. In this scenario, there are usually a variety of energy sources, such as photovoltaic, fan, etc., and the main role of firewood is to replace the power grid as a voltage source to support the load in the network.
At this stage, most manufacturers, in the scenario of diesel storage combination, usually use diesel as the main voltage source, and energy storage as a substitute for diesel, and the two energy sources cannot establish voltage frequency at the same time. This combination method is relatively simple, and the cooperation between energy storage and Chai hair is low.
Another way of combination is that the energy storage can be used as a voltage source with Chai Fa at the same time, and the energy storage can absorb the countercurrent that Chai FA can not absorb. Through the combination of this way, on the one hand, the capacity of the microgrid is improved, and the stability of the microgrid is also improved. Energy storage and Chai can be run separately or simultaneously, greatly increasing flexibility.

In industrial and commercial scenarios, there are various scenarios such as commercial computer rooms, laboratories, hospitals, etc. In such scenarios, the value and importance of equipment are high, and the requirements for power quality are also high. For example, test equipment, data servers, hospital life-support devices and other equipment, these equipment for the stability of electricity requirements are very high, usually the use of redundancy design, to prevent the sudden loss of power in the case of mains power, server power down resulting in data loss and other situations.
On the other hand, there are also cases where the load automatically stops running because of fluctuations in the frequency or voltage amplitude of the grid. At this time, energy storage systems can be installed to smooth grid fluctuations, thereby improving power quality.

On the one hand, industrial and commercial owners can achieve spontaneous self-use in the factory through self-investment photovoltaic and energy storage systems, and quickly reach the investment recovery period. On the one hand, it can also achieve green electricity and zero carbonization by purchasing green electricity.
