Wind is defined as the horizontal motion of air across the surface of the Earth, described by convention, as the direction from which the wind is blowing. Consequently winds blowing from the north are called northerly winds. Wind direction is usually indicated by a wind vane and is usually shown on a wind rose in steps of 10 degrees. However, most winds also have a vertical component, w hich is normally much smaller, but will gain some importance under certain conditions.
'Low-Cost' Renewable Energy Is Breathtakingly Expensive
Variable renewable energy VRE also called intermittent renewable energy sources IRES is a renewable energy source that is non- dispatchable due to its fluctuating nature, like wind power and solar power , as opposed to a controllable renewable energy source such as dammed hydroelectricity , or biomass , or a relatively constant source such as geothermal power. The use of small amounts of intermittent power has little effect on grid operations. Using larger amounts of intermittent power may require upgrades or even a redesign of the grid infrastructure. Several key terms are useful for understanding the issue of intermittent power sources. These terms are not standardized, and variations may be used. Most of these terms also apply to traditional power plants.
Penetration level of Wind Energy and Impact on Grid
Gravity exerts a pull on the planet's atmosphere just as it keeps us tethered to its surface. This gravitational force causes the atmosphere to push against everything it surrounds, the pressure rising and falling as Earth turns. The force exerted by an air mass is created by the molecules that make it up and their size, motion, and number present in the air. These factors are important because they determine the temperature and density of the air and, thus, its pressure. The number of air molecules above a surface determines air pressure.
Distribution systems are typically designed to operate in a single power flow direction: from the substation to the load. However, the integration of distributed energy resources, such as wind energy systems, can change the direction of the power flow, leading to a voltage rise in the feeder. In systems with high penetration of wind, overvoltage can occur, which is one of the major concerns regarding power quality issues.
