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 […]
Read MoreCreating the Digital Utility
The digital revolution is growing at an exponential rate. As the volume of data collection and exchange builds momentum, the time is ripe for utilities to reap the benefits that turning ’digital’ involves. In this white paper, we offer a practical guide to what strategic and measurable benefits data can bring to a water company […]
Read MoreThe Utility’s Guide to Evaluating Network as a Service (NaaS)
The AMI network is the backbone to your daily business operations. Utilities must carefully consider many factors when choosing a Network as a Service (NaaS) provider. This white paper serves as a tool to guide your decision making process. Understand what to look for, questions to ask, and options to consider as you research communication […]
Read MoreAchieving Predictable Reliability
Numerous considerations are in play for utility officials when choosing a data communication system. It is a substantial investment, with the eyes of regulatory agencies and customers watching intently. Among the smartest of decisions an official can make during the selection process is to minimize transmission risk and increase credibility by achieving predictable reliability. To […]
Read MoreSecurity and Resilience for Utility Network Communications
Utilities are rapidly implementing advanced communication networks, a component of the smart grid. The openness and ubiquity of these networks enable many of the benefits of Advanced Metering Infrastructure (AMI) systems, but this same openness can create a vulnerability to the same risks faced by enterprise networks and the internet. This paper reviews the range […]
Read MoreWireless Smart Grid Communications: A Mesh Versus Point-to-Multipoint Comparison
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: […]
