Mitigating the Impact of Unintentional Islanding on Electric Utility Transmission Systems from Distributed Energy Resources
Distributed energy resources (DERs) introduce an element of variability and unpredictability that adds complexity to distribution planning efforts. Unintentional islanding of interconnected systems can lead to sustained overvoltage conditions and bidirectional power flow. This poses a serious threat to both employee safety and grid reliability. Traditional protection schemes such as Direct Transfer Trips (DTT) offer […]

Utilities have discovered the benefits of wireless communications and now deploy them widely for Automated Meter Reading (AMR), Advanced Metering Infrastructure (AMI), Distribution Automation (DA) and Supervisory Control and Data Acquisition (SCADA). Two approaches have come to dominate the industry among electric, water and gas service providers seeking a backbone for their smart grid communications: […]
