From the perspective of the power generation side, the demand terminal for energy storage is the power plant. At present, the energy storage on the power generation side is mainly matched with wind and photovoltaic power stations, committed to solving problems such as "wind abandonment" and "light abandonment", which can improve wind and solar energy consumption and smooth new energy output.

We all know that wind power has a high wind curtailment rate in the process of generating electricity. Abandoning wind power does not mean abandoning the use of wind power, but rather saying that the wind is strong and can fully generate electricity, but it does not fully utilize wind energy and instead abandons it. This is because a large amount of wind power is not allowed to be injected into the power grid. The premise for stable operation of the power system is that power generation and consumption must always maintain a balance. If a large amount of power enters or loses in an instant, it will cause the system to lose stability, and the consequences are very serious.

It is precisely due to the limited throughput and consumption capacity of the power grid system that a large proportion of clean energy connected to the grid will lead to an increase in wind and light abandonment rates. Therefore, countries around the world are strengthening the consumption and storage capacity of the power grid. However, the power generation efficiency of clean energy sources such as photovoltaics and wind power is difficult to artificially regulate. Most of the time, there is a deviation from the curve of electricity demand. Under good lighting intensity and wind conditions, there will be a periodic oversupply. If extreme weather conditions occur, it will lead to low power generation efficiency and oversupply.

At this point, it is necessary to compensate for the uncontrollability of the new energy power system through large-scale energy storage. The energy storage system can effectively smooth the power generation output curve, perform peak shaving and valley filling, and improve the operational efficiency of the power system. Without the support of energy storage services, wind power and photovoltaic power will actually have a certain impact on grid regulation, and the long-term development of new energy will be constrained. Only by cooperating with energy storage can we better establish a flexible and low-carbon grid.
