摘要：

In recent years, the consensus control has become a research hotspot in microgrid cooperative control. However, when the VSG control is applied, the system has higher order, more parameters and more complex dynamic response. And there are few studies on the dynamic characteristics of parallel VSGs with the consensus control. Aiming at this problem, the small signal state space model of parallel VSG with consensus based secondary control is established in this paper firstly. Then the influences of damping, inertia, secondary control parameters on dynamic response are analyzed, and the design criterion of secondary control parameters is proposed. Finally, the simulation results verify the accuracy of model and correctness of conclusions. (C) 2020 The Authors. Published by Elsevier Ltd.
