My apologies for such a late reply to this question, but HOMER Energy (where I work) has just increased its online training opportunities in response to the COVID pandemic. You can find course listings here: https://www.homerenergy.com/services/training/index.html
Our training teaches you how to design microgrids with either of our two software pre-feasibility design and analysis tools: HOMER Pro, for off-grid and unreliable grid situations and HOMER Grid for grid-tied distribured energy projects that can be islanded for improved resilience.
As someone below mentioned, we are having a virtual conference in October with microgrid professionals from around the world. See www.microgridconference.com. Also if you want to read about different types of microgrids please check out some of the case studies on the HOMER Microgrid News (search for story about microgrids in Chile and Argentina that include hydro, since you're from South America!)
Hope to see you at the conference!
