IEEE: The expertise to make smart grid a reality

IEEE Smart Grid Newsletter - June 2014

Quantifying the Reliability of a PMU Network

The wide area measurement system (WAMS) is gradually becoming an important guarantee of security and stability in smart transmission grids. In the utility industry, WAMS is sometimes referred to as a PMU (phasor measurement unit) network, as synchronized PMUs are the most crucial elements in collecting real-time monitoring information. A PMU network provides much better observability and controllability in smart grid operations. However, like any other physical system, a PMU network itself can fail. The consequences of PMU network failure are serious and can include a large blackout. Therefore, the reliability of PMU networks should be quantitatively evaluated and assured.

Distributed Resource Integration with Transactive Control

One of sixteen smart grid demonstration projects funded under the U.S. stimulus bill of 2009, the Pacific Northwest Smart Grid Demonstration is focused squarely on transactive control technology. The control technology developed in the project can be thought of as a distributed decision-making technique. Decisions at nodal points are informed by both local and global information, as represented in transactive control signals shared by neighboring nodes.

A New Architecture for Distributed Energy Management

It is proposed that the utility be put at the center of the distributed energy equation and manage the output of all the distributed energy in its territory. The key to this approach is to use principles of transactive energy all the way down to the retail/premises level and to optimize all available sources of energy based on their pricing characteristics and user preferences.

SPIDERS: A Model for Utility Microgrids

The limited penetration of microgrids into the nation’s electric infrastructure can be attributed to uncertainty, both true and perceived, associated with designing, building and operating the systems. The Smart Power Infrastructure Demonstration for Energy Reliability and Security aims to develop and demonstrate a cyber-secure microgrid architecture that can be used to supply critical end-use loads when the bulk power system is not available. SPIDERS is strongly focused on transitioning the technologies, concepts and lessons learned to a broad number of stakeholders.

About the Smart Grid Newsletter

A monthly publication, the IEEE Smart Grid Newsletter features practical and timely technical information and forward-looking commentary on smart grid developments and deployments around the world. Designed to foster greater understanding and collaboration between diverse stakeholders, the newsletter brings together experts, thought-leaders, and decision-makers to exchange information and discuss issues affecting the evolution of the smart grid.
