Training was held in CESI premises in Milan, and there were 12 trainees.

Duration: 2 and 3 days

Contents (Part 1):

  1. Quick review of WIND FARMS and PHOTO-VOLTAIC theory
  2. Review of the available library models
  3. Quick review of the typical issues related to the usage of WIND FARMS an PHOTO-VOLTAIC
  4. Examples-exercises in the usage of WIND FARMS and PHOTO-VOLTAIC aimed at representing the typical issues included in the previous point
  5. Quick review of BATTERY STORAGE
