摘　　要：随着电网中新能源渗透率的提高,系统惯量降低改变了系统频率特性。因此,在新能源机组并网的情况下,对于频率惯性响应时空分布特性的研究显得尤为重要。针对这一问题,提出了从区域的角度来研究新能源电网频率时空分布特性。从频率动态响应特性出发,分析了频率时空分布特性的影响因素以及电力系统频率分区响应特性,进而研究新能源并网下频率时空分布特性。以10机39节点系统为例进行仿真,验证了上述理论分析的正确性和有效性,为进一步探索电网频率时空分布特性提供了有利依据。With the increase of new energy penetration in the power grid,the system inertia decreases,and the frequency characteristics of the system are changed.Therefore,the research on the time-space response of units is particularly important in the case of grid connection of new energy.To solve this problem,it is proposed to study the temporal and spatial distribution characteristics of the frequency of the new energy grid from the perspective of the region.Based on the frequency dynamic response characteristics,the influencing factors of frequency spacetime distribution characteristics and the frequency zoning response characteristics of the power system are analyzed,and then the frequency space-time distribution characteristics under the grid connection of new energy are studied.Taking the 10 machines 39 bus system as an example,the correctness and effectiveness of the above theoretical analysis are verified,which provides a favorable basis for further exploring the temporal and spatial distribution characteristics of the power grid frequency.
