Droop Control in Microgrids Laura Ramrez Elizondo Learning Objectives How is droop control implemented in a voltage source converter? What are conventional and inverse droop control strategies? What is a virtual impedance?

  1. Droop Control in Microgrids Laura Ramírez Elizondo

  2. Learning Objectives • How is droop control implemented in a voltage source converter? • What are conventional and inverse droop control strategies? • What is a virtual impedance? • What are the advantages and disadvantages of droop control?

  3. Droop Control Implementation in a VSI • Frequency droop control

  4. Droop Control Implementation in a VSI • Voltage droop control

  5. Conventional and Inverse Droop

  6. Conventional and Inverse Droop Inverse droop: • Active power vs voltage • Reactive power vs frequency Conventional droop Opposite droop Compatible with HV Yes No Compatible with rotating Yes No generators Active power dispatch Yes No Direct voltage control No Yes

  7. Droop Control with Physical or Virtual Impedance

  8. Disadvantages of Droop-Based Methods • Unstable region • High frequency oscillations

  9. Standards for Voltage and Frequency Deviations

  10. Summary
