shunt capacitors are used in power systems since the 1910s and are popular due to low cost and relative ease of deployment. The amount of reactive power supplied by a shunt capacitor is proportional to the square of the line voltage, so the capacitor contributes less under low-voltage conditions (frequently caused by the lack of reactive power).
A power transformer, usually used to change the utility distribution voltage to a lower voltage for use on the customer premises. Dolby A trademark for a noise reduction technique for analog sound recordings. dot convention A system for marking terminals on instrument transformers to maintain correct polarity. doubly fed electric machine
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially
In the field of power electronics the reduction of the effect of changes of influence quantities on the output quantity. stabilized power supply In the field of power electronics an equipment which takes electrical energy from a source and supplies it stabilized by means inside the equipment to one or more pairs of output terminals.
The amount of fuel energy required to produce electrical energy. Heat rate is the inverse of efficiency, incorporating a factor of 3600 due to the differing units of fuel energy (kJ) and electrical energy (kWh) – there are 3600 kJ in 1 kWh. Efficiency

The energy that a physical body possesses due to its motion, defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. The body continues to maintain this kinetic energy unless its velocity changes. Contrast potential energy. Kirchhoff's circuit laws. Also called Kirchhoff's rules or simply Kirchhoff's laws.
The decisions ("economic dispatch") are based on the dispatch curve, where the X-axis constitutes the system power, intervals for the generation units are placed on this axis in the merit order with the interval length corresponding to the maximum power of the unit, Y-axis values represent the marginal cost (per-MWh of electricity, ignoring the ...
