Fig. 2 The work of load power variation supplied by G-35.
It can be concluded that the main factors causing the generator frequency variation are the work done by the mechanical power variation, the work of load power variation supplied by the generators, and the work of transmission power loss variation undertaken by the generators.
In any case, it is well recognized that populations of some wild progenitors, such as teosinte, exhibit remarkable levels of standing genetic variation, supplying ample raw material for the operation of artificial selection (e.g., Doebley 2004; Buckler and Stevens 2006).
Asakura [2] further categorized the sources of travel time fluctuations in to three factors which are from demand side such as day to day traffic variation, supply side such as road closure due to accidents and external factors such as adverse weather effects and natural disaster.
The model takes into account batch units available in discrete sizes, and both raw material and product inventories accounting for seasonal variations for supplies and demands.
These control actions consist of a distribution of the variation between supply chain members, using the plan's slack in a collaborative way.
There is a large seasonal variation of supply, demand and price of cashmere.
Unlike wind, solar, or hydroelectric power, it isn't subject to hourly, daily, or seasonal variation: you supply the fuel and the right conditions and nuclear delivers the power you need on demand.
The frequency components outside the boundaries of local spectra are usually caused by the modulation of load variation and supply frequency, and the synchronization of different harmonic series local bands.
Sunlight, the energy source for Prochlorococcus, undergoes a regular and dramatic variation in supply each day.
