In order to study fast transition between autonomous mode and grid-connected mode for micro-grid

we present an operation modes control technology for wind power/ PV/ energy storage/micro-turbine combined heat and power（CHP） hybrid micro-grid. The whole framework for micro-grid operation modes control based on IEC 61850 standardized information network is proposed

including the fault detection module

synchronization check module

energy storage unit state analysis module

and autonomous/grid-connected mode control module. Then

the specific implementation method for each module is presented. Thereby

the experiments are carried out based on the micro-grid operation test platform. The test results show that the proposed micro-grid operation modes control is feasible to fast transfer the grid-connected mode to the autonomous mode and vice versa

and can provide effective techniques for fast and reliable operation control of micro-grid.
