The user side energy storage power station can achieve economic benefits through peak valley arbitrage, mainly reflected in the following aspects:
1、Utilization of peak valley electricity price difference：There is a difference in electricity prices between peak and low periods in the electricity market. User side energy storage stations can purchase cheap electricity during low periods for storage, and then sell the stored electricity to the electricity market during peak periods to obtain higher electricity prices. This peak valley arbitrage can improve the economic benefits of user side energy storage power plants.
2、Peak valley balance and power smoothing：User side energy storage stations can store energy during low valley periods and release energy during peak periods, thereby achieving grid load balance and smooth power changes. This helps to improve the reliability and stability of power supply in the power grid, reduce the peak load of the power grid, and save investment and operating costs of the power grid.
3、Reducing the cost of electricity consumption in the power grid：User side energy storage stations can store cheap electricity during low periods, and then use their own stored energy to meet electricity demand during peak periods, thereby reducing the cost of purchasing electricity from the power grid. Users do not need to purchase expensive electricity during peak hours, thereby achieving a reduction in electricity costs. The economic benefits brought by energy storage power stations in areas with significant differences in peak and valley electricity prices are considerable.
4、Reserve power and reserve power：The user side energy storage power station can serve as reserve power and reserve power supply. In the event of a power grid failure or power outage, the energy storage power station can be quickly put into use, providing emergency energy support and ensuring the user's electricity demand. This is of great significance for some key areas, such as medical institutions, communication base stations, etc. Energy storage power stations have greatly alleviated the electricity pressure on the power grid. When the power sector needs to use staggered electricity, energy storage power stations are a good equipment to avoid economic losses to users caused by power outages.
It should be noted that the economic benefits of user side energy storage power stations are also influenced by various factors, including electricity price differences, energy storage station capacity and efficiency, battery life and maintenance costs. Therefore, when analyzing the economic benefits of peak valley arbitrage, it is necessary to comprehensively consider the above factors, and conduct detailed data analysis and simulation calculations to accurately evaluate the economic feasibility and profit potential of the user side energy storage power station.
