Anyone have developed a microgrid which can work both as islanded and nonislanded mode?

I am trying to simulate a microgrid with wind generation system, photovoltaic system, and power storage system as sources and both linear and non-linear loads. It should work well both in grid connected and grid discnnected mode. 50Hz frequency system is preffered.
