Industrial and commercial energy storage Application mode
 | Peak shaving and valley filling |  | Electricity trading |
Through valley-hour charging energy storage and peak-hour discharge energy supply, we can reduce the electricity cost of enterprises or parks and save electricity costs for customers | On the electricity market trading platform, short-term electricity trading is carried out in combination with load forecasting to achieve increased revenue | ||
 | Off-grid backup |  | Virtual capacity increase |
In the event of power interruption, uninterrupted short-term power supply for important loads reduces economic losses caused by sudden load failure | When the short-term power consumption is greater than the transformer capacity, the energy storage system performs rapid discharge to meet the load energy demand requirements |
Grid-side energy storage application mode
| New energy power station | Effectively solve the problem of instability and intermittency of renewable energy power generation, and improve the penetration rate of renewable energy in the power grid | 01 |
| Frequency regulation | Using the rapid response ability of battery energy storage technology, participate in the AGC frequency regulation auxiliary service of the power grid, improve the response speed of the generator set and the KP value of the power plant, and obtain the power grid auxiliary service reward | 02 |
| Power auxiliary services | Power auxiliary services refer to market-oriented auxiliary services other than normal electric energy production provided by grid-connected power plants or power users to maintain the safe and stable operation of the power system and ensure power quality | 03 |
| Emergency power support | The flexible adjustment of energy storage can improve the safe and stable operation ability of UHV AC and DC power grids | 04 |
| Delays transmission and distribution investment | The application of energy storage can effectively improve the service life of power infrastructure, improve the degree of distributed energy resources, provide electric energy to remote communities, and effectively delay the investment process of transmission and distribution | 05 |
| Ensure the stability of power grid operation | A buffer layer is formed on the low-voltage side to absorb part of the photovoltaic power generation with excessive output, which is convenient for the dispatching department to control the power flow and ensure the stability of the power grid operation | 06 |
| Smooth new energy output | Through energy storage equipment, the power generation of new energy is stored, and the function of short-term fluctuation is provided when the fluctuation of new energy power generation fluctuates | 07 |
| Peak shaving | During peak hours, the energy storage system is supported by rapid discharge, which effectively relieves the pressure on the transmission and distribution station when the load is used intensively | 08 |
