The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behavior. It is, in essence, the âcontrol panelâ of our personality and our ability to communicate.
In order for the power grid to function, demand for energy must exactly match supply. Power demand is relatively predictable and conventional power plans, like nuclear plants and natural gas, can adjust output accordingly. Solar and wind power, however, cannot easily adjust output. They also provide power unpredictably relative to conventional power sources.
The smart grid will create a power network that is more reliable, flexible, secure and efficient. One of the challenges of renewable power generation like wind and solar power is that it can be interrupted, and this variability affects the stability of the power produced. FACTS devices address network capacity and stability as more renewable energy is brought online.
