Advanced Microgrid FunctionalitiesAdvanced microgrid functionalities must be addressed from the interconnected utility perspective as well as for the independent system.

The technical challenges are widely varied and comprehensive, but some have already been addressed by the industry and utilities. Technical solutions will be implemented within the system microcontroller, within some inverters or within ancillary devices. They include*:

Function 1. Frequency controlFunction 2. Volt/VAR controlFunction 3. Grid-connected-to-islanding transitionFunction 4. Islanding-to-grid-connected transitionFunction 5. Energy managementFunction 6. ProtectionFunction 7. Ancillary services (grid-connected)Function 8. Black startFunction 9. User interface and data management

The Functional Use Cases for Control and Operations of Advanced Microgrids

• Frequency control • Voltage control (grid-connected & islanding)• Grid-connected to islanding transition – intentional • Grid-connected to islanding transition – unintentional• Islanding to grid-connected transition• Energy management (grid-connected & islanding)• Protection• Ancillary services (Grid-connected)• Black start• User interface and data management

The Scope of IEEE PAR 2030.8

8/30/2016

• The scope is to develop a set of testing procedures allowing the verification, quantification of the performance and a comparison of the performance with expected minimum requirements of the different functions of the microgrid controller that are common to the control of all microgrids, regardless of topology, configuration or jurisdiction

• Microgrid controller system specifically controls the energy management– Includes control functions that define the microgrid as a system that

can manage itself, and operate autonomously or grid connected– Includes metrics for a comparison of the required control functions

• controller system enables connects and disconnects with the main distribution grid for exchange of power & the supply of ancillary services

• It is recognized that microgrid components and operational solutions exist in different configurations with different implementations

Ward Bower Innovations LLC 11

The Purpose of IEEE PAR2030.8

8/30/2016

• The purpose for establishing 2030.8 for testing microgrid controller systems is to enable interoperability of different controllers and components needed to operate controllers through cohesive /platform-independent interfaces

• It will establish standardized testing procedures to allow for flexibility and customization of components and control algorithms while ensuring minimum requirements are met

• It will strive to establish comparative performance indices. • The standardization focuses on testing functional requirements and

interoperability with various Distributed Energy Resource (DER) interfaces

• Other electrical system interfaces within the microgrid are considered• A standardized set of generic testing procedures will facilitate the wide

adoption of microgrid controller functional requirements .
