The operational steps for peak valley arbitrage in user side energy storage power plants are mainly summarized as follows:
1、Market analysis：Firstly, analyze the electricity market in the region, understand the electricity prices during peak and low periods, as well as the operating rules of the electricity market, understand the supply and demand situation of the electricity market, and collect local electricity price data, including prices at different time periods.
2、Analyze peak and valley periods and plan formulation: Based on the collected electricity price data, analyze the differences in electricity prices during different periods. Generally speaking, the electricity price during peak hours is higher than that during low periods. Develop an operational plan for peak valley arbitrage based on market conditions.
3、Selection and installation of energy storage equipment: Based on the user's electricity demand, load characteristics, and budget, select appropriate energy storage equipment, install energy storage equipment, and connect it to the power system to ensure that the equipment can operate normally.
4、Evaluate the energy storage efficiency and charge discharge efficiency of energy storage power plants: Energy storage efficiency refers to the efficiency of batteries during the storage and release of electrical energy, while charge discharge efficiency refers to the efficiency of batteries during the charging and discharge processes. These efficiencies will affect the economic benefits of energy storage power plants.
5、Charging during low periods and discharging during peak periods: During low periods, i.e. when electricity prices are low, start the energy storage plant and connect it to the power grid. By purchasing cheap electricity, convert it into stored energy and store it in energy storage devices. During peak hours, that is, during peak electricity demand, the energy stored in energy storage devices is released. This can be achieved by supplying electricity to one's own electricity load as needed, reducing the cost of purchasing electricity from the grid, or selling excess electricity to the electricity market to obtain higher electricity price returns.
6、Calculate economic benefits: Calculate the operating benefits and economic benefits of energy storage power stations based on local electricity pricing policies and electricity market conditions. Specifically, revenue can be calculated by comparing the purchase and sale prices of energy storage stations during peak and valley periods.
7、Determine the investment return period: Based on the calculated economic benefits and arbitrage opportunities, determine the investment return period. Generally speaking, the shorter the investment return period, the better the economic benefits of the project.
8、Develop optimization strategies: Based on the analysis results, develop appropriate strategies. If the investment return period is reasonable and there are arbitrage opportunities, then investment in energy storage power plants can be considered. According to the formulated optimization strategy, implement relevant measures to improve the economic benefits of energy storage power stations.
9、Monitoring economic benefits: After implementing optimization strategies, monitor the economic benefits of energy storage power plants to assess whether they meet expectations.
10、Continuous improvement: Based on monitoring and analysis results, continuously improve optimization strategies to further improve the economic benefits of energy storage power plants.
Please note that the above analysis is for reference only, and actual operations require adjusting strategies based on local policies and market conditions. At the same time, other factors need to be considered, such as policy risk, technical risk, market risk, etc.
