As the power system is moving toward an inverter-dominated system, this course is intended to inform the audience on the need for grid-forming inverters, including the definition, use cases, and performance requirements of these inverters. 

Attendees should acquire:

  • System needs from inverter-based resources in an inverter-dominated system 
  • The definition of a grid-forming inverter and how it differs from a grid-following inverter 
  • Grid-forming control methods and their high-level operation principles 
  • Use cases for grid-forming inverters in the distribution and transmission grid 
  • Performance requirements of grid-forming inverters in utility-scale microgrids 

Who should attend:

  • Engineers and consultants working in the areas of 
  • Transmission planning and operations 
  • Distribution planning and operations 
  • Microgrid design and operation 
  • Owners of inverter-based generation resources 
  • Inverter vendors 

Prerequisite skills, knowledge, certifications:

Basic understanding of power system operation and grid support from inverter-based resources


  1. Educate the audience on the definition of grid-forming inverters and how they differ from grid-following inverters 
  2. Inform the audience on the potential use cases of grid-forming inverters in T&D systems 
  3. Inform system planners and operators on the performance requirements of grid-forming inverters and key considerations in developing grid-forming inverter specifications 
  4. Inform plant owners about design considerations to meet grid-forming requirements


  1. Grid-forming inverters should be defined based on performance requirements rather than control design 
  2. Besides enabling inverter-based microgrids, alleviating inverter stability issues in weak transmission and distribution grids is another use case for grid-forming inverters 
  3. In a utility-scale microgrid, the performance requirements of grid-forming inverters should be designed such that if there are more than one grid-forming inverter, they can work collectively to satisfy the system requirements of the microgrid
