Abstract

The investigation of the dynamic characteristics of multi-converter systems is usually based on detailed modelling of the converters. This requires detailed control-related information about the converters, which is not suitable for grid operators and third-party research institutions to perform practical investigations of multi-converter grids. This paper proposes a validation and operation-oriented investigation approach to construct a system dynamics matrix of a multi-converter system with information on the grid topology, grid impedance and converter's setpoints. In this paper, a three-converters system is modelled and the information of the stable equilibrium surfaces is investigated. According to the continuity of the stable equilibrium surfaces, the grid-forming converter has better robustness to the loss of synchronisation of the grid-following converter. On the other hand, the grid-following converter is not able to maintain stable operation in case of loss of synchronisation of the grid-forming converter.
