Introduction
Embedded generation technologies are proved by researchers as one of the solution to satisfy the increasing electricity demand while optimizing the existing network (Jenkins, 2000). In Europe micro grid technology also potentially studied to supply green electricity to most important industries (Lasseter, 2002; Arulampalam et al., 2004). However, challenges are being made on keeping the micro grid running when the main grid was disconnected due to a fault and smooth reconnection of micro grid when fault is cleared.
The objective of this study is to find out the possibility of synchronizing a microgrid to the main grid at grid connection point, when it is disconnected due to a fault.
In this study, Nilambe 1.6 MW mini hydro generator with its surrounding grid shown in Figure 1 was taken as micro grid. It was studied whether the embedded generator could be kept running while feeding surrounding loads during a Grid failure. The frequency and voltage maintaining capability of this generator was also checked with shedding excess loads when it was islanded. Finally automated synchronizing control of this micro grid was studied once the grid was restored.
