Microgrid islanding operation experience

This paper describes the experience of islanding operation of a microgrid located in Provincial Electricity Authority (PEA)´s distribution network. The equipment for islanding operation and resynchronization were installed to enable the islanding operation of the microgrid. Moreover, the remote control equipment developed by PEA was installed to allow the remote operation from SCADA dispatching center. The experiment was set up to examine the performance of microgrid operation during the islanding and resynchronization process. The results show that the microgrid is capable of operation in both islanding and grid-connected modes without sacrificing the system stability and no power interruption.
