A tremendous effort is taking place worldwide to increase the amount of wind and solar generation interconnected to the grid, and it is very successful. Today’s power system has more renewable generation than ever before. With all the financial enticements, regulatory motivations and environmental inducements, tomorrow’s grid will only integrate more of it.
As the 21st century power system builds out, it is going to include a lot more wind and solar generation than it does today. To make it all work, there are big changes taking place on the grid and the application of energy storage systems is one of those. They are going to play a critical role in the successful integration of renewable energy resources into the grid.
Years ago, Charlie Smith, executive director of the Utility Variable-Generation Integration Group, summed it up in a past discussion by saying, “The Stone Age didn’t end because we ran out of stones.” The industry must move out of the Stone Age and take advantage of energy storage technology.
Following are images from T&D World's "Taming Renewables with Storage" feature, from the August 2014 Renewables supplement. The article discusses how renewable resources can become dispatchable with sufficient energy storage systems. See the full article text...
