Against the backdrop of time-of-use electricity pricing mechanisms,rising electricity prices for high-energy-consuming industries,and the decline in energy storage costs,the commercial and industrial energy storage market has shown tremendous potential and economic viability.Given the complexity and variability of commercial and industrial user loads,there is currently no unified and standardized guidance for energy storage allocation;during the preliminary planning stage of projects,conducting rapid and accurate investment return analysis for different commercial and industrial energy storage schemes is particularly important.Therefore,this paper,based on a multidimensional analysis and comprehensive consideration of commercial and industrial load and electricity characteristics,energy storage charging and discharging strategies,and basic electricity cost,proposes a method for configuring energy storage suitable for multiple application scenarios;on this basis,a cost-benefit model for commercial and industrial energy storage is established,and an assessment method that links energy storage configuration with the economic benefits of commercial and industrial energy storage is proposed.This method can quickly calculate the investment returns under different energy storage configuration schemes.Taking the industrial and commercial energy storage allocation of a certain province as an example,applying this method,it is recommended that users configure a storage scale of 24 MW/48 MW·h.After setting the calculation boundary parameters,the internal rate of return for the project is calculated to be 13.86%within minutes.
