Fractalgrid
In electric power distribution, a fractalgrid is a system-of-systems architecture of distributed energy resources or DERs. In a fractalgrid topology, multiple microgrids are strategically arranged to follow a fractal or recursive pattern. Fractals, or self-similar patterns, can be seen in nature. Clouds, river networks, and lightning bolts are a few examples of natural phenomena that display fractal features. In a fractalgrid, a microgrid may be composed of smaller microgrids or “fractal units”. In such a configuration, the network becomes one of simplified power flows and communications through distributed substations. Variations There are two main variations of the fractalgrid concept. Though not mutually exclusiveCleanSparks FractalGrid architecture is a bottom-up implementation while NRECA's flows from the top-down to reach similar architectural quality attributes. CleanSpark's FractalGrid This variation is a command-and-control platform that integrates energy storage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fractal
In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly smaller scales is called self-similarity, also known as expanding symmetry or unfolding symmetry; if this replication is exactly the same at every scale, as in the Menger sponge, the shape is called affine self-similar. Fractal geometry lies within the mathematical branch of measure theory. One way that fractals are different from finite geometric figures is how they scale. Doubling the edge lengths of a filled polygon multiplies its area by four, which is two (the ratio of the new to the old side length) raised to the power of two (the conventional dimension of the filled polygon). Likewise, if the radius of a filled sphere i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power Distribution
Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between and with the use of transformers. ''Primary'' distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through ''secondary'' distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level. The transition from transmission to distribu ...

Load Management
Load management, also known as demand-side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. This can be achieved by direct intervention of the utility in real time, by the use of frequency sensitive relays triggering the circuit breakers (ripple control), by time clocks, or by using special tariffs to influence consumer behavior. Load management allows utilities to reduce demand for electricity during peak usage times (peak shaving), which can, in turn, reduce costs by eliminating the need for peaking power plants. In addition, some peaking power plants can take more than an hour to bring on-line which makes load management even more critical should a plant go off-line unexpectedly for example. Load management can also help reduce harmful emissions, since peaking plants or backup generators are often dirtier and less efficient than base load pow ...

Network Segmentation
Network segmentation in computer networking is the act or practice of splitting a computer network into subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting performance and improving security. Advantages * Reduced congestion: Improved performance is achieved, because on a segmented network there are fewer hosts per subnetwork, thus minimizing local traffic * Improved security: ** Broadcasts will be contained to local network. Internal network structure will not be visible from outside. ** There is a reduced attack surface available to pivot in if one of the hosts on the network segment is compromised. Common attack vectors such as Link-Local_Multicast_Name_Resolution, LLMNR and NetBIOS poisoning can be partially alleviated by proper network segmentation as they only work on the local network. For this reason it is recommended to segment the various areas of a network by usage. A basic example would be to split up web servers, database ...

NRECA
The National Rural Electric Cooperative Association (NRECA) represents the interests of over 900 electric cooperatives in the United States. Cooperatives are not-for-profit and are owned by their membership. Founded in 1942, NRECA unites the country's generation, transmission, and distribution cooperatives found in 47 states, serving over 40 million people. It is headquartered in Arlington, Virginia, and its CEO is Jim Matheson. Electric cooperatives serve 12 percent of the nation's population, yet own 42 percent of America's distribution lines covering three-quarters of the country. Currently, over 90% of electric cooperatives include renewable generation in their portfolios, receiving 11 percent of their total power from renewable sources compared to 8 percent for the entire utility sector. In December 2020, co-ops under NRECA won $1.6 billion from the FCC's Rural Digital Opportunity Fund to provide rural broadband service to approximately 900,000 locations. In February 2021, ...

Energy Consumption
Energy consumption is the amount of energy used. Biology In the body, energy consumption is part of energy homeostasis. It derived from food energy. Energy consumption in the body is a product of the basal metabolic rate and the physical activity level. The physical activity level are defined for a non-pregnancy, pregnant, non-lactation, lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her basal metabolic rate (BMR): :\text=\frac Demographics Topics related to energy consumption in a demographic sense are: * World energy supply and consumption * Domestic energy consumption * Electric energy consumption Effects of energy consumption * Environmental impact of the energy industry ** Global warming * White's law Reduction of energy consumption * Energy conservation, the practice of decreasing the quantity of energy used * Efficient energy use See also * Efficient energy use, Energy efficiency * Energy efficiency in transpor ...

Camp Pendleton
Marine Corps Base Camp Pendleton is the major West Coast base of the United States Marine Corps and is one of the largest Marine Corps bases in the United States. It is on the Southern California coast in San Diego County and is bordered by Oceanside to the south, San Clemente and Orange County to the north, Riverside County to the northeast, and Fallbrook to the east. The base was established in 1942 to train U.S. Marines for service in World War II. By October 1944, Camp Pendleton was declared a "permanent installation," and by 1946 it became the home of the 1st Marine Division. It was named after Major General Joseph Henry Pendleton (1860–1942), who had long advocated setting up a training base for the Marine Corps on the West Coast. Today it is home to myriad Operating Force units, including the I Marine Expeditionary Force and various training commands. History Prior to World War II In 1769, a Spanish expedition led by Captain Gaspar de Portolá explored northward fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
