DESCRIPTION:In this talk\, the idea of operating inverters to mimic synchr
 onous generators is developed. We call the inverters that are operated in 
 this way synchronverters. The deployment of this technology would minimise
  the impact of the fast-growing number of grid-connected inverters on the 
 grid\, which is a potential threat to the overall stability of power syste
 ms. Synchronverters behave in the same way as conventional synchronous gen
 erators and thus are grid-friendly. The implementation and operation of sy
 nchronverters will be described in detail. The real and reactive power del
 ivered by synchronverters connected in parallel can be automatically share
 d using the well-known frequency and voltage drooping mechanism. Synchronv
 erters can also be easily operated in island mode and hence they provide a
 n ideal solution for micro-grids or smart grids. Both simulation and exper
 imental results will be demonstrated. Synchronverters have wide applicatio
 ns in distributed generation and renewable energy\, uninterrupted power su
 pplies (UPS)\, rotary frequency converters\, induction heating\, static sy
 nchronous compensator (STATCOM)\, HVDC transmission etc.
