Data Architecture for the Next-Generation Power Grid: Concept, Framework, and Use Case

To support next-generation power grid monitoring, protection, and control, we re-view and synthesize the new requirements and challenges of the enabling data architecture. We outline the necessary elements and a framework for the data architecture including the data path, synchronization and alignment layer, high-speed stream processing, databases, data service layer, and the interaction with analytics & control applications. We select and discuss wide-area damping control, a representative real-time closed-loop control application, as a use case to demonstrate the proposed data architecture.
