Tutorials and Advanced Concepts for Architecture of Electric Power Grids

System Architecture

A system architecture is the conceptual model that defines the structure, behavior, and essential limits of a system. An architectural description is a representation of a system whose purpose is to help think about the overall shape of the system, its attributes, and how the parts interact. System architectures are written, composed or specified. The discipline of System Architecture provides the formal principles and methods for writing system architectures.

Grid Architecture

Grid Architecture is the application of system architecture, network theory, and control theory to the electric power grid. A grid architecture is the highest level description of the complete grid, and is a key tool to help understand and define the many complex interactions that exist in present and future grids.



Prime Uses of Grid Architecture

  • Help manage complexity (and therefore risk)
  • Assist communication among stakeholders around a shared vision of the future grid
  • Identify and remove barriers and define essential limits
  • Identify gaps in theory, technology, organization, regulation
  • Provide a framework for complex grid-related development activities
