As the wind penetration rate in power systems continues to increase, its randomness and volatility pose significant challenges to grid stability. Energy storage systems, as an effectivecomplement to wind power, can rapidly adjust power output and help mitigate wind power fluctuations. However, the power response of wind turbines and energy storage systems in coordinated frequency regulation is constrained by nonlinear characteristics, complicating the design of control strategies.
This study focuses on the issue of nonlinear power constraints in wind turbine-energy storage coordinated frequency regulation, aiming to address key scientific problems such as modeling the nonlinear power characteristics of wind turbines and energy storage systems, designing coordinated control strategies that account for nonlinearities, and optimizing dispatch methods.
The research includes developing dynamic models for wind turbines and energy storage systems, analyzing the impact of nonlinear power constraints on frequency regulation performance, designing coordinated frequency regulation strategies based on nonlinear predictive control to achieve dynamic power allocation and rapid response, and validating the proposed methods through simulations. The expected outcomes will enrich the theory of wind power-energy storage coordinated frequency regulation, enhance the stability of wind power grid integration, and provide theoretical and technical support for grid operation with high renewable energy penetration.
