Stability Analysis of All Inverter Interfaced Generation Systems

This paper investigates the stability issues in large scale transmission systems when all the conventional synchronous generators are displaced with inverter interfaced generation(IIG). A network-based approach is proposed for mathematical analysis. The overall stability of the system is a function of inverter dynamics, load dynamics, network structures and parameters. Based on this framework, the influence of system topology, inverter parameters and dynamic load models on the system stability as well as how these factors interact with each other are well studied. Furthermore, a smart algorithm with high computational efficiency is designed for case studies. The simulation results show high conformity with theoretical analysis.
