Abstract :
In this paper mathematical models and control method of DGs in microgrid are researched, and a typical integrated model of microgrid is created by DIgSILENT, according to an experimental microgrid in Beijing. The effect on stability of microgrid operation caused by two typical microgrid operating conditions including disconnection from the main grid and PV output drop in island mode are simulated, with the changes in output of DGs, system voltage and frequency analyzed. Validity of the proposed model and its control strategy is simulation-examined..
