随着新能源渗透率的提高,研究新能源以自同步电压源形式接入后的系统频率动态特性对系统频率稳定分析具有重要意义。基于此,文中采用负荷容量为基准容量,构建了包含同步发电机、跟网型电流源接入新能源、构网型自同步电压源接入新能源在内的系统频率动态聚合模型,分别采用阻尼比、
H
∞
范数等指标分析了自同步电压源型新能源占比与自同步电压源控制参数对系统频率动稳态性能的影响。研究结果显示,自同步电压源型新能源占比对系统频率性能的影响存在临界范围,当自同步电压源型新能源占比超出临界范围时,占比提高对频率性能的提升作用明显降低。最后,通过基于RT-LAB的实时仿真,验证了所提系统频率动态聚合模型的有效性及分析结果的正确性。
With the increase of renewable energy penetration
it is of great significance for the system frequency stability analysis to study the dynamic characteristics of the frequency of the system with the integration of renewable energy by the self-synchronous voltage source. Based on this
by using the load capacity as the reference capacity
this paper constructs a system frequency dynamic aggregation model including the synchronous generator and the integration of renewable energy by the grid-following current source and the grid-forming self-synchronous voltage source. And the influence of the proportion of renewable energy by the self-synchronous voltage source and the control parameters of the self-synchronous voltage source on the dynamic and steady-state performance of the system frequency is analyzed by using the damping ratio and the
H
∞
norm index. The research results show that there is a critical range of the influence of the proportion of self-synchronous voltage source on the system frequency performance
and the effect of proportion increase on the frequency performance is obviously reduced when the proportion of self-synchronous voltage source exceeds the critical range. Finally
the effectiveness of the proposed system frequency dynamic aggregation model and the correctness of the analysis results are verified by the real-time simulation based on RT-LAB.
