User Terminal Power Control Based on Probabilistic Quantization in Federal Learning

Traditional grid-following wind turbines lack active voltage support capabilities, while grid-forming units, adopting voltage source self-synchronizing control methods, possess the ability to autonomously establish voltage and frequency. Hybrid grid-following/grid-forming wind power stations can achieve both voltage stability and efficient power generation in wind farm aggregation areas, representing a key paradigm for constructing new-type power systems. However, significant differences exist between grid-following and grid-forming wind turbines in terms of response mechanisms, control modes, and support characteristics. The response coupling during dynamic regulation processes makes balanced reactive power and voltage control in hybrid wind farms particularly challenging. To address these challenges, this paper first analyzes the control structures and regulation characteristics of grid-following/grid-forming units, clarifying applicable scenarios for different device types. Subsequently, it investigates the reactive power-voltage distribution characteristics and voltage support requirements in wind farms, proposing a reactive power allocation strategy for hybrid wind farms that coordinates turbine terminal voltage control with smooth system-wide voltage regulation. This strategy achieves balanced voltage control across the wind farm. Finally, a simulation test platform for hybrid grid-following/grid-forming wind farms is established, validating the effectiveness of the proposed strategy.
