Multi-Machine Cooperative Control Strategy of Wind Farm Participating in Power Grid Frequency Modulation
摘要
Abstract
[Objectives]Considering the difference of primary frequency regulation ability of wind turbines under different wind conditions in wind farms,the evaluation method of frequency regulation capability of wind turbines was optimized on the basis of sag control and inertia control strategy.[Methods]An improved multi-unit frequency modulation reference power cooperative control strategy was proposed.[Results]The introduction of multi-unit cooperative control method can effectively improve the distribution of frequency modulation reference power among units,thus effectively adjust the degree of each unit participating in the primary frequency regulation of the system.An improved cooperative control strategy was introduced on the basis of inertia control and sag control.According to the operation state of the unit under the actual wind condition,the reference power of the unit which can effectively participate in the primary frequency modulation was evaluated.The introduction of frequency modulation capability coefficient can realize the energy distribution of the reference value of frequency modulation power among units.[Conclusions]The cooperative control strategy can effectively protect the speed of wind turbine and improve the frequency response of power grid.关键词
