Abstract:
|
The recent grid integration of Distributed Energy Resources (DER) possibility the formation of
intentional islands in the case of a grid fault conditions. For such island formation is required an active
agent capable of governing the micro-grid connection state in a safe mode, especially in connection
and disconnection transients. This paper focuses on the design of a method oriented to carry out a
stable intentional disconnection, and later re-connection, of local grids from the main distribution grid
in an intentional way; also under unbalance load condition. Seamless transfer between grid-connected
and isolated mode has been achieved in an alpha-beta stationary reference frame with a frequency
based synchronization control loop. Simulation and experimental results are provided to verify the
proper performance of the proposed solution. |
