近年来,同调等值方法被广泛应用于大型系统的动态等值中,得到的降阶模型能够准确反映系统的动态响应,其中,代表性的慢同调算法具有对故障位置和严重程度不敏感等优点。然而,由于模型限制及准确性差的问题,使得传统慢同调算法难以应用于分布式发电网络中。为此,提出了一种适用于下垂控制并网逆变器网络的慢同调与聚合方法,依据奇异摄动理论建立慢同调模型并分析阻尼的影响,以解决下垂控制逆变器网络的适用性问题。同时,将模糊

Recently
coherency equivalence method has been widely used in the dynamic equivalence of large-scale systems
and the obtained reduced-order model can accurately reflect the dynamic response of the system. Among them
the slow coherency algorithm as a representative has the advantages of being insensitive to the location and severity of the fault. However
due to model limitations and poor accuracy
traditional slow coherency algorithms are difficult to apply to the distributed generation network. To this end
a slow coherency and aggregation method applicable to the droop-controlled grid-connected inverter networks is proposed. Based on the singular perturbation theory
a slow coherency model is established and the influence of damping is analyzed to solve the applicability problem of droop-controlled inverter networks. Meanwhile
the fuzzy

-means spatial clustering algorithm is used in the space vector of the modal matrix to achieve the purpose of accurately identifying the coherent power sources. Finally
a reduced-order model is established by using the aggregation method
and the simulation results of 10 parallel inverters verify the effectiveness of the proposed method.
