Hello Adriana,

My answers is yes, provided that the variable sources (wind, and solar) are hosted in a grid that contains sufficient other energy sources for instantaneous power balance. Such other sources may be nuclear generators, or advanced energy storage such as hydrogen. I will list some relevant publications in another comment.

Thanks Dear Dr. EL-Shimy.

You are welcome Adriana. There some chapters in the following book that may be useful elaborated answers to your question. Chapter 3 in the first book, chapter 1 in the third book, and significant parts of the second book.

The following article also considers several advanced issues related to the impacts of variable generation, and low/zero interia generators of the dynamic performance of power grids.

May I ask you the reasons of selecting the coal instead of all fossil fuels in your question?

I have set this example because it was the first thing that came to my mind. Thanks, Dr. El-Shimy.

It is OK. Good luck with your study

Thanks Dr.

I hope so

Yes,

Dear Adriana, I think that it is one of goals today to replace fossil fuels by renewable energies. Yes, we should start from coal, because it has the worst CO2 impact per unit of energy. But since coal is cheap, it is difficult to do that in free market. People were talking about carbon tax, but it should be at least $50 per ton to replace coal with more expensive but more eco-friendly natural gas. Free trade in carbon permits in Europe was not successful because price varied between 0 and 30 $, giving no incentive for change.
