Description: 

The concept of the microgrid has evolved to fully recognize the benefits of microgrids in terms of market participation, renewable integration, cost savings and reliability and resiliency to the grid. PAP 24 addresses these interrelated aspects of microgrids that are emerging as an important component of the power delivery system.

The microgrid connects to the macro-grid or other microgrids at the point of common coupling (PCC).  The IEEE 1547 series defines the interconnection requirements and basic requirements of transitioning to and from grid-connected mode and islanded mode. PAP 24 addresses the interrelated needs of the microgrid and the broader grid in terms of communicating and interacting with macrogrid operations and markets and with other microgrids, in addition to communicating with the individual resources within the microgrid.

Coordinated and consistent electrical interconnection standards, communication standards, and implementation guidelines are required for microgrids and their interaction with the macrogrid. Although there are standards that define the basic microgrid connection and disconnection process, there are no standards that define the grid interactive functions and operations of microgrids with the macrogrid. PAP 24 focuses on the grid facing functionalities and communications (e.g., microgrid to/from macrogrid). PAP 24 examines the interoperability of the information models and signals used by microgrid controllers.

A broad set of stakeholders and SDOs is needed to address this coordination and evolution in order to revise the IEEE 1547 electrical interconnection standard as appropriate to accommodate Smart Grid requirements and to extend the DER object models and communication requirements in IEC 61850-90-5 and IEEE 1547 to microgrids as distinct interconnected entities. PAP 24 coordinates interrelated activities with IEEE SA, IEEE PES, DOE, national laboratories, NIST, IEC, EPRI, UL, SAE, NEC-NFPA70, and regulatory bodies to ensure optimal implementation of standards supporting likely future scenarios across a wide range of use cases. The cooperative relationship between the microgrid, distribution utility, ISO and markets is given particular attention by PAP 24.

Goals: 

  1. Scoping Document: Develop a Scoping Document to identify the range of applications to be addressed and standards needed to address microgrid applications.
  2. Use Cases: Develop Use Case scenarios and business processes to define the different requirements for electrical interconnections, focusing on scenarios involving potential microgrid formation, grid operations with significant market involvement of aggregated DER systems, and adequate responses to frequency and voltage anomalies to avoid power system instabilities.
  3. Advanced grid-interactive interconnection standards for microgrids
  4. Unified microgrid controller standard: Develop an IEEE Standards Board Project Authorization Request (PAR) that can be used to define a new microgrid controller standards working group, addressing communications that implements functional performance and cooperative control between the microgrid and area EPS.
  5. Regulatory Framework: Examine the regulatory issues related to wide scale microgrid deployment and define technical solutions being considered for their integration into the power delivery system.
  6. Microgrid Information Model standards: Continue development of interoperable information model standards for DER and microgrids

Brief abstract: 

PAP 24 addresses the interrelated aspects of microgrids as they evolve as an important component of the power delivery system. It does this within a broad range of interrelated factors, including markets, renewable integration, economics and reliability and resiliency of the grid.

PAP 24 contributes to the revision of IEEE 1547 series with particular attention to interconnection requirements and basic requirements of islanded systems and their transition to and from grid-connected mode and islanded mode.

PAP 24 coordinates activities related to the electrical interconnection standards, communication standards, and implementation guidelines that are required for microgrids and their interaction with the macrogrid. PAP 24 focuses on the grid facing functionalities and communications (e.g., microgrid to/from macrogrid).

PAP 24 engages a broad set of stakeholders and SDOs for interrelated issues for Smart Grid requirements and communications for microgrids as distinct interconnected entities. PAP 24 coordinates interrelated activities with IEEE SA, IEEE PES, DOE, national laboratories, NIST, IEC, EPRI, UL, SAE, NEC-NFPA70, and regulatory bodies to ensure optimal implementation of standards. Encouraging the cooperative relationship between the microgrid, distribution utility, ISO and markets is fundamental to the work of PAP 24.
