The main application scenarios of energy storage power stations on the power generation side include smooth output of renewable energy, thermoelectric decoupling, promoting new energy consumption, frequency regulation auxiliary services, etc

-1. The smooth output of renewable energy is achieved by building energy storage stations to suppress fluctuations in renewable energy generation output, stabilize output levels, and smooth the generation output curve, meeting the assessment of new energy output.
-2- Decoupled configuration of thermoelectric energy storage improves the regulation ability of cogeneration units, enhances thermal flexibility, promotes clean energy heating, and enhances the renewable energy consumption capacity of the power grid.
-3- Promote the new energy consumption and energy storage system to store the excess electricity generated by renewable energy when resources are sufficient, and transmit it when resources are insufficient, effectively alleviating the phenomenon of wind and solar abandonment in new energy power plants.
-4- Frequency regulation auxiliary service: The frequency regulation speed of thermal power units is slow, and the response signal has hysteresis. Energy storage power stations can assist traditional thermal power units or rely on large-scale new energy units and other power sources to provide frequency modulation services.

The main application scenarios of grid side energy storage power stations include grid power supply guarantee, grid peak shaving, delaying grid transformation and upgrading, and grid terminal voltage support

-1. Compared with ordinary rotating backup power stations, the grid guaranteed power storage power station has a faster response speed and can be used as a backup power source that can be quickly started in emergency situations, ensuring the power supply of the regional grid;
-2. The peak shaving and energy storage system of the power grid achieves power generation, electrolytic coupling, and load regulation through high storage and low discharge, reducing the difference between peak and valley loads, and achieving load level control and load transfer of the power system;
-3- Delaying the installation of energy storage equipment in the transmission network for grid upgrading and renovation, improving the transmission capacity of the grid, reducing investment in transmission and transformation equipment, improving energy utilization efficiency and overall asset utilization level of the grid;
-4- The voltage support energy storage equipment at the end of the power grid can provide fast power buffering, absorb or supplement electrical energy, provide active power support, and compensate for active or reactive power to stabilize and smooth the fluctuation of power grid voltage.

 

The main application scenarios of user side energy storage power stations include arbitrage of peak valley difference for large users, promoting distributed energy consumption, improving energy quality and participating in demand response.

-1. Large user peak valley arbitrage absorbs excess electricity during periods of low electricity prices for storage, and releases it when the electricity price is high, utilizing the peak valley electricity price difference to achieve profits on the user side.
-2- Promote the consumption of distributed new energy sources in a large proportion of microgrid systems, and configure energy storage systems to adjust the balance between power generation and load, maximizing the utilization of renewable energy.
-3- Improving energy quality and energy storage can be achieved through the control of power electronic devices, utilizing redundant energy storage capacity to address power quality issues such as low power factor and voltage imbalance that occur during the production process.
-4 - The demand response energy storage system participates in demand response through high storage and low release, and obtains subsidies or preferential electricity prices. With the improvement of demand side management policies in the future, the benefits brought by demand response will also increase.

Peak valley price difference arbitrage is the main channel for user side energy storage profits. In the new situation where industrial and commercial users enter the electricity market and power grid purchases electricity on behalf of others, peak valley electricity prices are determined by market electricity prices, and the peak valley price difference may decrease, compressing the profit space of user side energy storage; Shared energy storage value is the core of independent energy storage operations. In the early stages of auxiliary service market construction, the market cannot fully reflect the utilization needs of various entities on the power generation side, grid side, and user side for energy storage. Therefore, in existing policy scenarios, it is necessary to directly purchase the required energy storage capacity from independent energy storage enterprises or users, or coordinate the needs of all parties by the grid to uniformly dispatch independent energy storage, Realize accurate services and effective sharing of energy storage value for independent energy storage to energy demand entities
