Pages: 4 - 13 Abstract: Telecommunications networks are at the core of transforming the power grid into the smart grid. The latter, according to the most familiar definition, is the superposition (or integration) of information and communications technologies infrastructure and electric infrastructure to leapfrog the latter from the last century to modern days (https://www.nist.gov/ctl/smart-connected-systems-division/smart-grid-group/smart-grid-framework). Communication network technology was introduced in utilities initially to support the deployment of supervisory control and data acquisition (SCADA) systems. These SCADA systems allowed operations personnel to remotely monitor and control generation, transmission and distribution, power plants, and substation equipment from utility operations centers, enhancing the power grid’s operational efficiency. In addition, communication networks found use in the remote support of automated circuit breakers known as teleprotection systems. More recently, grid communications enabled grid-edge technologies through the Internet of Things (IoT) and synchrophasor-based wide-area measurement systems (WAMSs). PubDate:

Pages: 15 - 17 Abstract: Communications networks have been an integral part of power system operations for many decades. These networks provide operators with the situational awareness necessary to manage the grid. They enable coordination with crews and operators to maintain safety during normal operations and efficiently manage restoration when outages occur. They provide the backbone for coordinated protection schemes and increasing levels of automation for fast response to changing conditions and maintain system stability. The measurements and other data gathered through these networks also provide input into the engineering analysis and planning processes for the electric system. PubDate:

Pages: 18 - 26 Abstract: Here’s a frank assertion: The United States cannot reasonably hope to meet its decarbonization goals unless its electric utilities deploy modern, private, wireless broadband communications networks. Drawing that connection between decarbonization and broadband capabilities is less complicated than it sounds (Figure 1). In short, addressing climate change requires reduced reliance on fossil fuels to generate electricity and more reliance upon renewable resources, which the grid is not designed to fully accommodate. Ramping up renewables requires a smarter grid and that means using millions of widely distributed sensors to create data, applications to analyze data, and smart devices to take action based upon data. Collecting and communicating all that data requires—here it is—a utility-grade wireless broadband network. PubDate:

Pages: 27 - 37 Abstract: GPSs are among the most widely available global navigation satellite systems (GNSSs) in use today. This free technology provides high-accuracy positioning, navigation, and timing (PNT) services that enable many applications. Many critical infrastructure systems and assets depend on PNT services, which include electrical power grid, telecommunication infrastructure, financial, transportation, agriculture, and emergency response systems.

Pages: 38 - 47 Abstract: Due to the proliferation of internet-of-things (IoT)-based technologies in the last several years, digital computing hardware and software technologies have seen massive performance improvement. Additionally, these technologies provide lower costs for comparatively higher computation and storage, more compact size hardware, and compatibility with a large selection of operating systems. Furthermore, communication protocols have increased the penetration of single-board computers in many consumer and industrial applications. This article presents the application of a state-of-the-art edge computing infrastructure to the electrical power distribution grid. Electrical power distribution is becoming increasingly complex with the large degree of integration of distributed energy resources (DERs). The distribution system also experiences many different undesired events, such as different types of temporary and permanent faults, loss of measurement data, and cyberattacks. This article highlights a small-scale experimental validation of edge computing in power distribution automation that can be used for classifying different faults, detecting anomalies in the grid, measurement data recovery, and other advanced analytics techniques.

Pages: 48 - 57 Abstract: The traditional approach to planning the distribution grid has focused on reliability in the context of gradual and reasonably predictable load growth. Forecasts of load growth, combined with asset management practices, were used by system planners to identify upgrades to the system to maintain or improve reliability. The decisions, typically based within load flow analysis tools, included considerations about contingency scenarios and corporate forecasts (i.e., top-down predictions at a summary level of what would happen in a particular area that could impact load growth and behavior). Today, this traditional approach no longer fits all purposes. PubDate:

Pages: 58 - 67 Abstract: The electrical grid is undergoing a fundamental change with the introduction of smart grid technologies. In particular, power substations have been evolving toward more automated systems. Power substation communication networks evolved from infrastructures mostly formed by serial devices to Ethernet-based digital communications networks, accelerating with the introduction of the IEC 61850 set of standards. However, this evolution inherited the shortcomings of the traditional decentralized network management. This article explores the upcoming evolution of IEC 61850 to meet the groundbreaking programmable network technologies: software-defined networks (SDNs) and programmable data planes (PDPs). Here, we describe how recent proposals leverage SDNs to improve network management tasks such as topology discovery, multicast traffic management, and quality-of-service (QoS) provisioning, among others in IEC 61850-based systems. We also outline potential improvements to critical network management tasks in power substations using PDP features such as in-band network telemetry. Finally, we discuss different challenges in the management of the communication networks of smart power substations and addressing them with the implementation of programmable networks. PubDate:

Pages: 68 - 77 Abstract: Waveforms are the most granular and authentic representation of voltage and current in power systems. With the latest advancements in power system measurement technologies, it is now possible to obtain time-synchronized waveform measurements, i.e., synchro-waveforms, from different locations of a power system. The measurement technology to obtain synchro-waveforms is referred to as a waveform measurement unit (WMU). WMUs can capture the most inconspicuous disturbances that are overlooked by other types of time-synchronized sensors, such as phasor measurement units (PMUs). WMUs also monitor system dynamics at much higher frequencies as well as much lower frequencies than the fundamental components of voltage and current that are commonly monitored by PMUs. Thus, synchro-waveforms introduce a new frontier to advance power system and equipment monitoring and control, with direct applications in situational awareness, system dynamics tracking, incipient fault detection and identification, condition monitoring, and so on. They also play a critical role in monitoring inverter-based resources (IBR) due to the high-frequency switching characteristics of IBRs. PubDate:

Pages: 89 - 92 Abstract: The use of electronic communications in conjunction with electric power systems dates back to almost the beginning of electricity in the United States, not surprising given the geographically dispersed nature of electric power infrastructure. As power system technology advanced, communications shifted from analog to digital, and uses expanded to include grid state telemetry transport, protection and control, metering data transport, electricity market participation, interorganizational coordination, and customer communication.
