Electromagnetic Design Considerations for Fast Acting Controllers

With very fast controllers now being applied to electric power and distribution systems, interaction between controllers is always a possibility. A simple method for testing the sensitivity for controllers to interact was developed through the concept of “Global Gain Margin” analysis:
