Coordinated Dispatch of Flexible Resources and Thermal Generation Based on Variable Wind Power Consumption Region

With the increasing penetration of renewable energy in recent years, the safety and dispatch of power systems have drawn a lot of attention. A method based on a combination of bi-level programming (BLP) and interval projection algorithm (IPA) is proposed to solve a coordinated dispatch model with an energy storage system (ESS) and pumped storage unit considering the impact of large-scale wind power uncertainty and volatility. Finally, the validity of the model is verified in modified IEEE-RTS 1979, and the influence of flexible resources on wind curtailment, load shedding, and operation cost is analyzed. Results demonstrate that flexible resources could facilitate the ability of renewable energy consumption and the model can strike a balance between the security and economy.
