Adaptability of business models for the wind farm-flexible load joint operation system to enhance profit and grid integration

With the growing penetration of wind energy in China, the main grid operator imposes stringent requirements on the accuracy of wind farm output, prompting wind power producers to explore new business models to enhance profitability. To mitigate wind power uncertainty on the source side while saving energy bills on the load-side, this paper proposes a framework for the wind farm-flexible load joint operation system (W-FJOS). Based on the operational requirements of the main grid, the types of services that can be developed by the W-FJOS are analyzed, and the applicable business models are designed. Taking the participation of W-FJOS in electricity trading and valley filling ancillary services as an example, this paper compares the operating strategies of W-FJOS under different business models and presents the bases for business model selection. Numerical results indicate that, compared with traditional dispatch model, the two business models proposed in this paper not only improve the benefits for participants but also promote the nearby consumption of wind power. Moreover, the diverse services organized by the W-FJOS can further increase the profit potential of both the wind farm and flexible loads while supporting the integration of wind farms to the grid.
