针对风电场输出功率的强波动性对交直流互联电网调频的影响，提出了基于协作式分布式模型预测控制的交直流互联电网调频控制方法，以提高风电经交直流通道外送互联系统的频率稳定性，克服集中式模型控制方法扩展性差的缺点，该控制策略具有全局最优解。(Aiming at the influence of strong fluctuation of wind farm output power on frequency modulation of AC/DC interconnected power grid, a frequency modulation control method for AC/DC interconnected power grid based on cooperative distributed model predictive control is proposed to improve the frequency stability of wind power interconnected system via AC/DC channel and overcome the poor expansibility of centralized model control method. The disadvantage of this control strategy is that it has a global optimal solution.)
