含低电压穿越(LVRT)控制的光伏单元在电压大幅跌落时将采用无功优先原则,从而呈现有功出力变化,进而参与系统频率响应。为此,提出一种考虑规模化光伏LVRT特性的系统频率响应建模方法。首先,基于传统频率响应模型分析光伏规模化接入对系统的惯量水平、一次调频的影响,刻画电压大幅跌落场景下光伏电站控制切换行为引发的有功功率-频率的响应路径。然后,考虑光伏电站中单元众多、特性各异特点,归类3种典型LVRT有功特性并建立其划分边界,采用容量加权法计算光伏等值单元参数,并基于两阶段斜坡方法拟合非线性恢复集群的有功特性,建立光伏电站LVRT全过程的等值有功时域表达式。进一步地,将光伏电站LVRT有功变化量作为扰动激励引入传统频率响应模型,根据LVRT有功变化量时序特点,将其分段表征为阶跃、斜坡等形式,进而获取频率响应解析解,并由此分析LVRT特性对最大频率变化率、频率最大偏移和准稳态频率偏差等指标的影响。最后,在含光伏电站的5节点测试系统中验证所提建模方法的准确性和有效性。
Photovoltaic (PV) units equipped with low voltage ride-through (LVRT) control adopt a reactive power priority principle during significant voltage drops
resulting in variations in active power output and subsequent participation in system frequency response. To address this
a modeling method for system frequency response is proposed
taking into account the LVRT characteristics of large-scale PV. First
based on the traditional frequency response model
the impact of large-scale integration of renewable energy sources such as PV on system inertia and primary frequency regulation is analyzed. This analysis characterizes the active power-frequency response pathway triggered by control switching behavior at PV stations during significant voltage drops. Subsequently
considering the numerous and diverse characteristics of units within a PV station
three typical LVRT active power characteristics are classified
and their dividing boundaries are established. The equivalent unit parameters are rapidly obtained by using a capacity-weighted approach. A two-stage slope method is employed to approximate the nonlinear active power characteristics of clusters
thereby establishing an equivalent active time-domain expression for the entire LVRT process of PV power stations. Furthermore
the active power variation due to LVRT at PV power stations is introduced as a disturbance excitation into the traditional frequency response model. Based on the temporal characteristics of the active power variation due to LVRT
it is segmented and represented as step changes
slopes
and other forms to obtain the analytical solution of frequency response. The impact of the LVRT characteristics on indicators such as the maximum rate of frequency change
the maximum frequency deviation
and the quasi-steady-state frequency deviation is analyzed. Finally
the accuracy and effectiveness of the proposed modeling method are validated in a 5-bus test system incorporating PV power stations.
