The revenue of wind-storage system is composed of wind generation revenue, energy storage income and its cost. With the TOU price, the revenue of the wind-storage system is determined by the total generated electricity and energy storage performance.
The annual revenue of the wind-storage coupled system is 12.78 million dollars which is the income of wind generation only sold to the grid or customer. With the decrease of energy storage plant cost and the increase of lifetime, the best storage capacity and the corresponding annual income of wind-storage coupled system increase.
The installed capital costs for wind power systems vary significantly depending on the maturity of the market and the local cost structure. China and Denmark have the lowest installed capital costs for new onshore projects of between USD 1 300/kW and USD 1 384/kW in 2010.
When the energy storage plant lifetime is of 10 years, and the cost is equal to or less than 300 $/kWh, with the increased efficiencies of both charging and discharging processes, the installed storage capacity and the annual revenue of the wind-storage coupled system increase.
When the energy storage system lifetime is of 10 years, and the cost is equal to or more than 375 $/kWh, the optimization configuration capacity is 0 MWh, which means no energy storage installation. The annual revenue of the simulated wind-storage system is 12.78 million dollars, which is purely from the sale of wind generation.
