摘要：

For effective aggregation and equivalence of distribution network containing different control types of distributed photovoltaic systems，a generalized composite load model and a two-stage model parameter aggregation and equivalent method considering grid-following and grid-forming distributed photovoltaic sys⁃ tems are proposed. The generalized composite load model is formed by paralleling the equivalent models of grid-following and grid-forming photovoltaic systems with the traditional composite load models to effectively fit the grid-connected characteristic of the actual distribution network. Based on the parameter sensitivity analysis and the improved differential evolution algorithm，the model parameters are determined by the aggre⁃ gation and equivalence，which avoids the disadvantage of large dispersibility of identification solutions caused by too many unknown model parameters. The self-description ability，generalization ability and parameter stability of the proposed model are verified based on PSCAD and MATLAB. © 2023 Electric Power Automation Equipment Press.
