Customer ServiceIn general, the initial cost of an energy storage power station mainly includes the investment cost of the energy storage unit, power conversion unit, and other investment costs such as labor and service costs for initial installation. The specific calculations of these three parts used the formulas in Appendix 2 of literature [ 29 ].
However, no matter how the energy storage power station participates in the electricity market, the IRR of both power stations does not exceed 10%. This means that there is always a risk of loss in the investment of energy storage power stations.
Energy storage stations have different benefits in different scenarios. In scenario 1, energy storage stations achieve profits through peak shaving and frequency modulation, auxiliary services, and delayed device upgrades . In scenario 2, energy storage power station profitability through peak-to-valley price differential arbitrage.
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. (1) Analysis of Peak–Valley Electricity Price Policy
The results show that the economic benefits of energy storage can be improved by joining in the capacity market (if it exists in the future) and increasing participation in the frequency regulation market.
In this paper, the cost of energy storage is divided into three categories, namely the investment cost, the operating cost in the markets, and other costs. The remaining parts of this section elaborate on these three kinds of costs, respectively, and the benefits model is introduced in the next section.
