In 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 ].
When the system is at time t, the system total power generation output can be expressed as: (1) P G (t) = {P P V (t) − P E S (t) (Energy storage charging) P P V (t) + P E S (t) (Energy storage discharge)
By calculating the investment cost and arbitrage income of the energy storage plant, the configuration capacity of the energy storage plant is obtained when the wind-storage system’s net income of the reaches the maximum.
In this model, the equivalent profit of energy storage in the configuration stage is calculated based on the expected profit in the operation stage. Meanwhile, the expected profit in the operation stage also depends on the optimization of energy storage capacity configuration in the configuration stage.
At present, the investment cost of a pumped storage power station is about 878–937 million USD/GW, which is far higher than that of a battery storage power station, and is closely related to location. For battery energy storage, the initial cost mainly depends on different materials.
In the energy market, energy storage stations gain profits through peak-valley arbitrage. That is, the energy storage system stores electricity during low electricity price periods and discharges it during high electricity price periods.
