Synthetic load modelling considering the influence of distributed generation

Abstract

In order to establish a load model with distributed generation which is suitable for large-scale power system transient simulation under the background of high permeability of new energy, firstly a four machine integrated load model structure that describes the mixing of distributed new energy and traditional load is constructed in this paper, then a reduced order equivalent algorithm for distributed new energy clusters is proposed to determine the parameters of the distributed power equivalent model. Finally, an example is given to verify the effectiveness of the proposed method. The simulation results verify that the proposed method can accurately simulate the comprehensive load characteristics of distribution network with distributed generation.
