摘　　要：常规的智能电网稳定性控制以电压信号调频为主,在实际应用过程中受到新能源波动性、随机性的影响,存在电网失稳的问题,因此,设计了考虑分布式新能源波动性的智能电网稳定性控制方法。分析风机输出、光伏发电机组出力、蓄电池储能、微型燃气轮机输出等波动性,提取出智能电网分布式新能源波动性特征。基于分布式新能源波动性构建电网稳定性控制模型,在恒压条件下,分析信息网络与物理电网之间的控制关系,确保智能电网的暂态稳定性控制效果。优化智能电网稳定性控制因子,将转子转速、转子攻角作为稳定性控制因子,进一步实现智能电网的稳定性控制。采用实例分析,验证了该方法的稳定性控制效果更佳,能够应用于实际生活中。Conventional stability control of smart grids mainly relies on voltage signal frequency modulation.In practical applications,it is affected by the volatility and randomness of new energy sources,leading to the problem of grid instability.Therefore,a stability control method for smart grids considering the volatility of distributed new energy has been designed.Analyze the volatility of wind turbine output,photovoltaic generator output,battery energy storage,and micro gas turbine output to extract the characteristics of distributed new energy volatility in smart grids.Based on the volatility of distributed new energy,a stability control model for the power grid is constructed.Under constant voltage conditions,the control relationship between the information network and the physical power grid is analyzed to ensure the transient stability control effect of the smart grid.Optimize the stability control factors of smart grid,using rotor speed and rotor angle of attack as stability control factors to further achieve stability control of smart grid.Through case analysis,it has been verified that the stability control effect of this method is better and can be applied in practical life.
