Dynamic Impedance Based Analysis of Microgrids

Microgrids are networks of electricity users with local source of supply and able to operate independently from the external power system. This type of grids commonly integrate renewable energy based generation which are interfaced by means of power electronics devices. On this regard, the high pene...
