New challenges with solar and wind (Brazil)

Countries that have significantly increased the share of solar and wind in their power matrices have seen the emergence of new challenges, especially regarding the dispatch of their generation systems.

Although the sun and the wind have relatively predictable average characteristics, they show significant seasonal variations (they change with the seasons) and also on a daily basis.

The need to harmonize the dispatch of the available power plants by the System Operator is a new challenge. 

It is a "novelty" because the bulk of the plants were designed to be dispatched "on a regime basis". And so, in this new environment, there is an associated "new", additional cost, which needs to be recognized, planned and paid for. The alternative is to improvise - which is always more expensive!
