Abstract:Deployment of data generation devices, such as sensors and smart meters, has been accelerating towards the vision of Smart Grid. With insufficiencies of the legacy power grid communications protocols, increased data generation and communications bring about new challenges in collecting the data securely, efficiently and in a scalable fashion. Power operators are increasingly concerned about the data collection and processing to ensure smooth and effective operations. In this paper, we present a secure, and scalable data communications protocol for Smart Grid data collection. Under a hierarchical architecture, relay nodes (aka data collectors) collect and convey the datam securely from measurement devices to the power operator. While the data collectors can verify the integrity, they are not given access to the content, which may pave the way for third party providers to deliver value-added services or even the data collection itself. We further present optimization solutions for minimizing the total data collection time. An optimal, but intractable solution is complemented with two fast heuristics. Extensive simulations show that heuristics provide a good approximation to the optimal formulation with fast running times.
