Summary:
Microgrid is one of the structures for connecting dispersed power sources with local loads in power network. The islanding state is the exceeded idea for power supply, then the virtual grouping networking is considered to introduce microgrids into conventional accomplished power networks. In order to keep the safety operation of micro-generators in microgrid, switching strategies for generators have been applied but not discussed from the standpoint of dynamics. In this paper, the dynamics of the virtual microgrid is modeled by a hybrid automaton under control for keeping the balancing restriction of power flow. It is shown that the hybrid control is effective to keep the system in safe at realistic level.
