How much money does a simulated wind-storage system make?

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.

What is the annual revenue of wind-storage coupled system?

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.

How a wind-storage coupled system can increase the initial investment?

When integrating the energy storage plant, it stores the wind power when the electricity price is low, and releases it when the price is high. The total income of the wind-storage coupled system can be significantly increased. However, it will increase the initial investment by adding energy storage system.

Can integrated energy storage system generate more revenue than wind-only generation?

The integrated system can produce additional revenue compared with wind-only generation. The challenge is how much the optimal capacity of energy storage system should be installed for a renewable generation. Electricity price arbitrage was considered as an effective way to generate benefits when connecting to wind generation and grid.
