Future Power Grid

Focus Area One – Networking and Data Management

From Grid Optics

The future power grid is expected to deploy 100 million smart sensors and meters with various data transfer speeds. The resulting data volume can be at peta scale (1015) over a one-year time period. Power grid planners and policy makers need to have tools to quickly retrieve and analyze these volumes of data to make real-time decisions.

This focus area will address the gaps in networking and real-time data management by developing advanced algorithms, techniques, and software tools. These tools and techniques will deliver solid outcomes that support the future power grids’ ability to:

  • identify, filter, and reduce data based on conditions and locations to ensure real-time performance,
  • define scientific principles, requirements and resources to enable large-scale information network modeling and simulation environments; enabling the evaluation of performance and scalability challenges under real-time constraints,
  • develop operational sensor prototypes that allow adaptive autonomous operation supporting new distributed control paradigms, and
  • address and develop capabilities for secure real-time data transfer (data in motion) and create new methods that ensure integrity, privacy and confidentiality of devices through new cryptographic and non-cryptographic management techniques.

To tackle these questions, we will expand the size and scope of the EIOC to include a flexible and reconfigurable network infrastructure design laboratory, which will validate the models, frameworks, algorithms and tools being developed within the FPGI.

Furthermore, we will develop a data management middleware that advances the state of the art and will be optimized for use in the power grid. The data management middleware will be flexible and scalable to allow data sources and consumers to be added easily and dynamically in response to changes in the power grid. This research will provide a solid foundation to deploy next generation real-time data management systems for the power grid.

We will also focus on simplifying the deployment challenges of large-scale power grid networks by addressing configuration and routing aspects relevant to efficiency and reliability. PNNL will perform research on extending multi-topology routing protocols to support richly connected mesh network topologies and enable multi-path, multi-criteria routing in wired and wireless networks. Another field of research in this focus area will be new routing protocols in order to prevent traffic diversion (false route injection) and denial of service attacks. Lastly, by tackling operational complexity associated with public key infrastructures, certificate revocation, identity and key management, we will improve cyber security.
