3.3.1 Generation Technologies for Smart Grid
In addition to allowing better management of the legacy electric system, smart grid has
the potential to better integrate different kinds of generation. Enabling the integration
of renewable energy - both distributed renewable generation and large-scale renewable
generation - is among the most prominent and influential smart grid promises. The specific
technologies associated with this important smart grid function include specific electricity
generation technologies at boththe largescale andthe distributed small scale, aswell asthe
technologies required to effectively interface between the grid and renewable generation.
Although different renewable technologies are often grouped together and considered
as a single set of technologies (wind, solar, geothermal, etc.), it is important to recognize
that different technologies are often involved in large-scale renewable power generation
and distributed-small-scale renewable installations. Technologies, policies, and activities
to promote large-scale renewables are in some cases very different than those involved in
