What is the capacity of a wind farm?
Through Table 3 analysis, when there is only one wind farm in the alliance, the capacity of the energy storage facilities required by the wind farm 3 is the largest, with a capacity of 80 MW/h, followed by the capacity of the energy storage power station configured only by the wind farm 2, which is 78MWh.
How does a wind farm work?
All the electricity from the wind farm without energy storage is sold to the grid and users. The annual revenue is 12.78 million US dollars. 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.
What is the revenue of wind-storage system?
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.
How does energy storage work in a wind farm?
After energy storage is integrated into the wind farm, one part of the wind power generation is sold to the grid directly, and the other part is purchased and stored with a low price, and then is sold with a high price through the energy storage system.
Is a wind farm connected to the grid market?
A wind farm with an energy storage device is considered as a whole to be connected to the grid market. Firstly, the energy storage device stores abandoned wind generation to eliminate curtailment. Secondly, it stores wind generation when the price of electricity is pretty low.
What influences the power balance curve of wind farm 3?
Wind farm 3 power balance curve. Fig. 9 analysis indicates that the change trend of the shared energy storage power station is influenced by the charging and discharging state of the energy storage, which, in turn, is contingent upon the renewable energy power generation power and the grid-connected power demand.
