As part of its ongoing effort to improve the safety and reliability of its electric system, PG&E routinely uses a specialized helicopter to wash a targeted set of power lines that tend to accumulate significant amounts of contamination throughout the year such as dirt, salt and bird excrement.
Today, volt/VAr optimization is one of the key investment areas of the smart grid. It not only controls reactive power flow with drives losses on distribution feeders, but it also reduces peak demand which is critical for utilities. For more information, download Model behavior: Using distribution models to deliver smart grid volt/VAr control.
Renewables. Wind and solar are increasing their presence and importance on the grid, thanks in part to advances in technology at all levels of the power system. Download Advances in wind energy technologies in the context of smart grid to learn about some of these advancements, and how they are bringing greater control, mitigating intermittencies, and reducing the effect of electrical disturbances.
