A fully decoupled model for the study of power-frequency behaviour during a power system restoration test

This paper presents a model for the study of bottom-up power system restoration tests. The model is built for quick and suitable validation of power-frequency correlation during a restoration test, the most stressed process into a system with low regulation energy. All involved components are modelled by SISO systems describing both power generation controls and load behaviours. The simulation results are widely discussed through the analyses of four load scenarios, with the aim of scanning all possible worst cases in terms of load steps
