Operational Frameworks for Utility and Integrated Microgrids

This paper provides an overview of the operational, planning, and control framework required for a utility-integrated community-based microgrid. Design, planning, and operational requirements are reviewed along with microgrid control hierarchy and technology enablers. Special focus is given to the integration of the microgrid with the utility grid system and how utilities can leverage microgrids to complement existing utility grids and customers.

 

The first part of the paper describes the various tasks involved in the design, engineering, and implementation of a utility microgrid project. The second part of the paper outlines the common operating practices and the challenges in control and protection system development for a microgrid. The third part of the paper describes microgrid functional requirements, emerging technologies, and the integration of the microgrid with the utility grid.
