Energy storage system configuration principles:
The purpose of configuring the energy storage system in this project is to supplement the photovoltaic power generation system. Because the photovoltaic power generation system may be affected by weather factors, its output power fluctuates frequently.
This fluctuation will have an impact on the stability of the power grid, especially when the state grid power is outage.
In order to avoid the impact of photovoltaic power generation output fluctuations on the power grid during a state grid power outage, an energy storage system of a certain scale can be configured.
At the same time, when the load is low, photovoltaic power generation can be stored in the energy storage system, increasing the photovoltaic utilization rate and reducing the use of state grid power to save costs.
The energy storage system has the characteristics of high-power rapid discharge, which can supplement the grid discharge at the moment when the photovoltaic output fluctuates and maintain the stability of the grid.
Some application scenarios of industrial and commercial energy storage:
1. Power reserve and stable power supply: Industrial and commercial energy storage systems can be used for power reserve to balance the fluctuations between energy supply and demand. During peak hours of industrial and commercial electricity consumption, energy storage systems can release stored electricity to ensure stable power supply and avoid the impact of power fluctuations on production and life.
2. Smart microgrid: Industrial and commercial energy storage can build a smart microgrid system together with renewable energy. This system can generate, store and distribute electricity locally, reduce dependence on traditional power grids, and improve the reliability and stability of power grids.
3. Grid frequency regulation and peak-valley filling: At the grid level, industrial and commercial energy storage can participate in frequency regulation services, that is, respond to adjustments in power demand in a short period of time. In addition, energy storage systems can also be used to fill the peak-valley differences in power demand and improve the efficiency of the power system.
4. Power load management: Energy storage systems can help industrial and commercial users optimize power load management, by charging during off-peak hours, releasing electricity during peak hours, reducing peak power consumption, and thus reducing energy costs.
5. Independent energy system: Industrial and commercial facilities in some remote areas or without access to traditional power networks can use energy storage technology to establish independent energy systems to meet their basic energy needs.
