IEEE 2030.10-2021

This standard covers the architecture of a dc microgrid for rural and remote applications with a nominal distribution voltage of 48 V. It defines voltage and power quality metrics for power supplied to loads attached to such a microgrid. This standard focuses on the power distribution portion of a microgrid and addresses sources only in the way that they are attached to the grid. It does not impose either minimum or maximum current limits. Users of this standard are responsible for observing all applicable laws and regulations related to power grid and microgrid design, operation, and maintenance. Compliance with the provisions of this standard does not imply compliance to any such legal or regulatory requirements.

The purpose of this standard is to address the needs of the electrical power industry to provide access to electricity in areas where a national grid infrastructure may not be available. DC microgrid applications can also provide power where infrastructure costs or other issues prohibit connection to the national grid even in places where a national grid is available. This standard provides the framework to allow for deployment of distributed generation, storage, and use of electricity based on identified requirements and existing technology. Further, it has the goal of facilitating the use of clean renewable generation of electricity in these applications. The most important use of these microgrids is to supply electricity to people in remote locations without access to the primary ac grid. Low cost and safety are critical. Simplicity and reliability are important to their needs as well.

New IEEE Standard - Active. 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.
