DESCRIPTION:The microgrid concept represents one promising solution to fac
 ilitate the integration of large shares of renewable energy sources into t
 he electrical grid. In general\, a microgrid gathers a combination of gene
 ration units\, loads and energy storage elements at distribution level int
 o a locally controllable system\, which can be operated either in grid-con
 nected mode or in islanded mode\, i.e.\, in a completely isolated manner f
 rom the main transmission system. The present talk covers several relevant
  aspects in the operation of microgrids. In particular\, main operation mo
 des of inverter-interfaced generation units are reviewed and a model of a 
 microgrid is presented. Furthermore\, three important performance criteria
  in such networks are introduced\, namely frequency stability\, voltage st
 ability and power sharing. Control schemes to address these problems are d
 iscussed. The analysis is illustrated via simulation examples of a microgr
 id based on the CIGRE benchmark medium voltage distribution network.
