Economic Analysis of Customer-side Energy Storage Considering Multiple Profit Models

There are many scenarios and profit models for the application of energy storage on the customer side. With the maturity of energy storage technology and the decreasing cost, whether the energy storage on the customer side can achieve profit has become a concern. This paper puts forward an economic analysis method of energy storage which is suitable for peak-valley arbitrage, demand response, demand charge and other profit sources. This method comprehensively considers such factors as energy storage capacity attenuation, capacity income, tax deduction and exemption. On this basis, the economy of customer-side energy storage in typical provinces of China is calculated, and the impact on power grid enterprises is analyzed. Finally, the relevant suggestions are put forward.
