In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
The factors that influence the business model include peak–valley price difference, frequency modulation ratio of the market, as well as the investment cost of energy storage, so this paper will discuss from the following perspectives.
Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
According to their characteristics, two energy storage capacity configuration schemes are set up, including local storage of surplus electricity and local balance of surplus electricity for Internet access.
On this basis, an optimal energy storage configuration model that maximizes total profits was established, and financial evaluation methods were used to analyze the corresponding business models.
