Balancing Power Systems with Large Shares of Wind and Solar Energy
Power system operation includes balancing supply and demand at each instant. Wind and solar energy increase uncertainty and variability in the system and thus balancing needs. Balancing is done by adjusting output levels of some of the power plants, by charging and discharging storage, or by adjusting demand via market signals to increase or decrease electricity usage. Just like the other options, wind and solar power plants can also be used to provide balancing.
