中文摘要
:
随着新型电力系统的提出，新能源渗透下的智能电网得到巨大发展。以风电、储能为代表的高比例新能源和大量电力电子设备并网，使得传统火电比例降低，在一定程度上带来了许多频率安全问题。为明晰风-储参与调频下电网频率态势，首先根据传统火电、风电、储能频率响应模型分析了各调频单元调频控制原理；根据调频控制原理对各调频单元进行参数整定，并得到风-储参与调频下电网的参数整定关系；其次通过稳态频率误差公式得到稳态频率误差与传统火电、风电调频系数的数量关系，利用伯德图分析储能控制比例参数对频率稳定性的影响，并根据根轨迹图分析惯性时间常数对智能电网频率稳定趋势的影响；最后通过Matlab/Simulink仿真平台对理论分析进行验证。仿真表明通过时域和频域对频率特性进行分析可有效预测火电、风电、储能参与调频下智能电网频率态势，可为风-储参与调频下电网安全稳定运行与控制提供指导。
