Abstract: In order to solve the contradiction between direct power purchase and wind power consumption, large consumers may contribute to wind power accommodation by direct power purchasing as proposed in this paper, upper and lower spinning reserves are used to deal with the uncertainty of wind power, and the energy storage system is introduced to make up for the shortage of spinning reserve caused by higher demand. A Stackelberg Game model is established aiming at the optimal capacity of wind power integration in the context of direct power purchase by large consumers. The model takes power generation companies as leaders and wind farms as followers. Finally, the improved particle swarm optimization algorithm is applied in simulation analysis on the IEEE 30-node system with wind farm. Case study shows that the proposed method is valid.

Key words: direct power purchase by large consumers, spinning reserve, energy storage system, wind power uncertainty, wind power accommodation, Stackelberg game
