IEEE 2030.10-2021

The design and operation of a dc microgrid for rural or remote applications based on extra low voltage dc (ELVDC) to reduce cost and simplify stability are discussed in this standard. Such microgrids are typically operated without connecting to a nation's electric power system.

IEEE 2857-2021

This document describes a complete communications specification, encompassing layers 1 to 4 of the Open Systems Integration (OSI) network model, for a secure, wireless mesh communications network, using open standards communications and cybersecurity standards from standards organizations including Institute of Electrical and Electronics Engineers (IEEE) and Internet Engineering Task Force (IETF). The specification describes the functionality of the physical (PHY layer), medium access control (MAC layer), the network layer, transport layer and security parameters including certificate format for a highly scaleable and secure wireless mesh network for critical infrastructure ipv6 wireless communications networks.

IEEE 1138-2021

The performance, test requirements, procedures, and acceptance criteria for a transmission line overhead ground wire (a.k.a. shield wire, static wire, earth wire, skywire) with optical fibers commonly known as optical ground wire (OPGW) are covered in this standard. Functional requirements such as electrical, mechanical, optical fiber, environmental, and packaging, and test requirements related to design, installation, in-service, and maintenance, including routine tests are also covered.

IEEE 802.1CS-2020

Protocols, procedures, and managed objects for a Link-local Registration Protocol (LRP) to replicate a registration database from one end to the other of a point-to-point link and to replicate changes to parts of that database are specified in this standard. A facility is provided to purge the replicated database if the source becomes unresponsive. LRP is optimized for databases on the order of 1 Mbyte.

IEEE 2030.11-2021

A key concept and requirement for an operational and effective deployment of a large number of distributed energy resources (DER), which include sources of power and demand response, to enable the provision of flexibility and grid services, is the aggregation of DER. This aggregation function, as well as the functions required to enable grid services, are provided by DER management systems (DERMS). A functional specification for a DERMS and a description of the grid services that aggregated DER can provide the distribution and transmission systems is provided by this guide. Implementation issues and the interoperability requirements of a DERMS with…

IEEE 1679.1-2017

Guidance for an objective evaluation of lithium-based energy storage technologies by a potential user for any stationary application is provided in this document. IEEE Std 1679-2010, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications is to be used in conjunction with this document. Secondary (rechargeable) electro-chemistries with lithium ions as the active species exchanged between the electrodes during charging and discharging are included in the category of lithium-based batteries for the purposes of this document. Lithium-ion, lithium-ion polymer, lithium-metal polymer, and lithium-sulfur batteries are examples of secondary lithium-based batteries. Primary (non-rechargeable) lithium…

IEEE C62.43.1-2020

Covered in this guide is the application of surge protective devices (SPD) and surge protective circuits (collectively called surge protectors) used to protect information and communication technology (ICT) circuits, including smart grid. This guide is not intended to cover individual surge protective components. Specifically excluded from this guide are stand-alone ac power protectors.

IEEE 2030.1.1-2021

Direct-current (dc) charging is a method of charging that facilitates rapid energy transfer from the electric grid to plug-in vehicles. This method of charging allows significantly more current to be drawn by the vehicle versus lower rated alternating-current (ac) systems. A combination of vehicles that can accept high-current dc charge and the dc supply equipment that provides it has led to the use of terminology such as “fast charging,” “fast charger,” “dc charger,” “quick charger,” etc. DC charging and ac charging vary by the location at which ac current is converted to dc current. For typical dc charging, the current…
