Intermittent Sources
Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or bioenergy, or relatively constant sources, 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. Options to absorb large shares of variable energy into the grid include using storage, improved interconnection between different variable sources to smooth out supply, using dispatchable energy sources such as hydroelectricity and having overcapacity, so that sufficient energy is produced even when weather is less favourable. More connections between the energy sector and the building, transport and industrial sectors may also h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar Energy
Solar energy is the radiant energy from the Sun's sunlight, light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include designing a building for better daylighting (architecture), daylighting, selecting materials with favorable thermal mass or light-dispersing properties, and organizing spaces that ventilation (architecture), naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technolo ...

Reliability Engineering
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time. The ''reliability function'' is theoretically defined as the probability of success. In practice, it is calculated using different techniques, and its value ranges between 0 and 1, where 0 indicates no probability of success while 1 indicates definite success. This probability is estimated from detailed (physics of failure) analysis, previous data sets, or through reliability testing and reliability modeling. Availability, testability, maintainability, and maintenance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synoptic Scale Meteorology
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of or more. This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones). Most high- and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere. Low-pressure areas and their related frontal zones occur on the leading edge of a trough within the Rossby wave pattern, while high-pressure areas form on the back edge of the trough. Most precipitation areas occur near frontal zones. The word '' synoptic'' is derived from the Ancient Greek word (), meaning "seen together". The Navier–Stokes equations applied to atmospheric motion can be simplified by scale analysis in the synoptic scale. It can be shown that the main terms in horizontal equations are Coriolis force and pressure gradient terms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aralvaimozhy Station
Aralvaimozhi is a panchayat town in Kanniyakumari District in the state of Tamil Nadu, India. It is a small town situated in southern India. The town was earlier called as ''Aramboly'' during the colonial period. History Aralvaimozhi Pass was a strategically important gap or mountain pass in the southernmost end of the Western Ghats. It connected erstwhile Travancore with the Madras Presidency. Many of the invasions faced by the Chera and the successor kingdoms came via this ghat. The name "Aral" was derived from the fort built and maintained by the rulers of Venad and later by the kingdom of Travancore to defend the kingdom from invasions from the eastern regions. It is also said that Aralvaimozhi means whispering wind. The whistling sound of wind in the region might have led to such a name. Aralvaimozhi Fort was one of the most important forts of Travancore. It was constructed around 1740 by Eustachius De Lannoy along with Udayagiri Fort, Vattakottai Fort and Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Its nicknames include "Gem City", a reference to its fine natural harbor, the "Gem of the Great Lakes"; and more recently, "Flagship City", from a local marketing effort to play up the homeport of Oliver Hazard Perry's flagship ''Niagara''. Manufacturing continues to play a large part in Erie's economy, with rising contributions from insurance, healthcare, higher education, technology, service industries, and tourism. Like the other Great Lakes port cities, Erie is acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power Forecasting
A wind power forecast corresponds to an estimate of the expected production of one or more wind turbines (referred to as a wind farm) in the near future, up to a year. Forecast are usually expressed in terms of the available power of the wind farm, occasionally in units of energy, indicating the power production potential over a time interval. Time scales of forecasts Forecasting of the wind power generation may be considered at different time scales, depending on the intended application: * ''very short-term'' forecasts (from seconds up to minutes) are used for the real-time turbine control and electrical grid management, as well as for market clearing; * ''short-term'' forecasts (from 30 minutes up to hours) are used for dispatch planning, intelligent load shedding decisions; * ''medium-term'' forecasts (from 6 hours up to a day) are used for to make decisions for switching the turbine on or off for safety or conditions on the market; * ''long-term'' forecasts (from a day up ...

Tidal Power
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed and that economic and environmental costs may be brought down to competitive levels. Historically, tide mills have been used both in Europe and on the Atlantic coast of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
