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.
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.
With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.
Wind energy in Europe is not only an environmental imperative but also an increasingly sound financial investment. We've seen that the cost of wind energy systems can vary widely – from a £2,000 roof-mounted micro-turbine in the UK to multi-million-euro mega-turbines on a Spanish hillside or off the German coast.
