Over the past year, the Department of Energy has been putting an increased focus on technology to integrate renewable energy into everyday grid operations. This work has included opening loan guarantees to distributed renewables, grants to support field tests of distributed energy integration, and future funding plans to support the development of grid modernization technologies. Now the DOE’s blue-sky research agency, ARPA-E, is getting into the action — or, as befits its mission, ahead of the action. Last month, ARPA-E announced $33 million in grants for its Network Optimized Distributed Energy Systems (NODES) program, meant to help 12 university, corporate and DOE laboratory projects that are trying to turn grid-edge assets into networked “virtual storage” systems. These projects are meant to “enable real-time coordination between distributed generation, such as rooftop and community solar assets, and bulk power generation, while proactively shaping electric load.” That could allow utilities to manage greater than 50 percent renewable penetration on the grid, “by developing transformational grid control methods that optimize use of flexible load and distributed energy resources.” This is not a unique concept. Distributed energy resource management software, or DERMS, platforms are being developed to tackle this challenge in one way or another, with grid giants like Siemens and Toshiba and startups such as Spirae, Enbala, Integral Analytics and Smarter Grid Solutions providing different pieces of the puzzle. Beyond that, there’s work being done by consortia such as Duke Energy’s Coalition of the Willing and Pacific Northwest National Laboratory’s transactive energy pilot project to allow lots of distributed energy assets to communicate and act in concert to solve local and system-wide grid challenges. Some of the projects funded by ARPA-E’s NODES program would help support these kinds of ongoing distributed energy resource (DER) integration efforts, while others would go several steps beyond what today’s utility grid control platforms and DERs are built to handle. Here’s a short description of each project and its aims. Greentech Media (GTM) produces industry-leading news, research, and conferences in the business-to-business greentech market.

Methods of operating a communication node are provided. A method of operating a communication node may include transmitting a first power line communication signal from the communication node to a sensor device that is at or adjacent an electric grid device. The method may include receiving from the sensor device a second power line communication signal that is responsive to the first power line communication signal, at the communication node. Moreover, the method may include determining a distance between the communication node and the electric grid device by measuring an electrical parameter of the second power line communication signal, at the communication node. Related communication nodes are also described.

Methods of operating a communication node are provided. A method of operating a communication node may include receiving data from an electric grid device via a network interface. The method may include processing the data from the electric grid device at the communication node. Moreover, the method may include transmitting a filtered portion of the data to an electric utility head end system, after processing the data at the communication node. In some embodiments, a method of operating a communication node may include using a message broker controlled by a virtual machine in the communication node to provide a protocol to interface with a field message bus that includes a standards-based or open-source Application Programming Interface (API). Related communication nodes and computer program products are also described.
