新能源大规模并网条件下系统惯量水平降低、空间分布不均衡问题日益突出,传统同步机系统惯性中心视角下的系统总惯量指标无法准确衡量扰动后系统频率动态响应的空间差异性。为描述系统结构、惯量分布的空间差异与系统频率响应差异间的关系,首先,从机电波理论新视角出发,构建频率波透射系数与系统拓扑结构、惯量分布和线路电纳间的关系函数;其次,提出电力系统离散模型的连续化处理方法,进而建立反映发电机节点间联系紧密程度及差异程度的透射系数矩阵和透射差异矩阵;在此基础上,提出了基于归一化透射差异矩阵的系统空间节点分群方法,将惯量分布、频率抗扰能力相近的发电机节点划分到同一群;最后,针对由实际电网简化得到的网格状电网模型,基于PSD电力系统分析软件(PSD Power Tools)验证了分群方法的有效性。
The problem of decreasing system inertia level and unbalanced spatial distribution under the condition of large-scale integration of renewable energy is becoming more and more prominent. The total system inertia index from the perspective of inertia center of the traditional synchronous machine system cannot accurately measure the spatial differences of the system frequency dynamic response after disturbances. In order to describe the relationship among the system structure
the spatial difference of the inertia distribution and the difference of the system frequency response
firstly
from the new perspective of the electromechanical wave theory
the relationship function among the transmission coefficient of the frequency wave and the system topology
the inertia distribution and the line electrodynamics is constructed. Secondly
the continuous processing method for the discrete model of the power system is proposed
and then the transmission coefficient matrix and transmission difference matrix reflecting the degree of closeness and difference between the generator nodes are established. On this basis
a spatial node clustering method based on the normalized transmission difference matrix of the system is proposed to classify nodes with similar inertia distribution and immunity to disturbance into the same group. Finally
the effectiveness of the clustering method is verified based on the PSD power system analysis software (PSD Power Tools) for the grid-like grid model simplified from the actual power grid.
