Modelling of inverter for stability analysis of microgrid

摘要

If microgrid is connected with main grid, there will be no problem of stability. But after islanding, stability issues occurs. For stability analysis of microgrid the effect of control strategy used in inverters is necessary to study. Load and network parameters also affects on stability of system. The controller of inverter, load and network should sense the signals accurately and quickly because these controller parameters participates in small signal stability of microgrid. Sensitivity analysis is introduced in this paper which shows the effect of each and every parameter on stability of microgrid.
