  2. Unit commitment problem in electrical power production

    en.wikipedia.org/wiki/Unit_Commitment_Problem_in...

    This has, in turn, very significantly increased the impact of uncertainty in the system, so that ignoring it (as traditionally done by taking average point estimates) risks significant cost increases. [22] This had made it necessary to resort to appropriate mathematical modeling techniques to properly take uncertainty into account, such as:

  3. Generator (circuit theory) - Wikipedia

    en.wikipedia.org/wiki/Generator_(circuit_theory)

    A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. [1] These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor.

  4. Capability curve - Wikipedia

    en.wikipedia.org/wiki/Capability_curve

    Due to high cost of a generator, a set of sensors and limiters will trigger the alarm when the generator approaches the capability-set boundary and, if no action is taken by the operator, will disconnect the generator from the grid. [3] D-curve expands with cooling. The D-curve for a particular generator can be expanded by improved cooling.

  5. Cost estimate - Wikipedia

    en.wikipedia.org/wiki/Cost_estimate

    A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost ...

  6. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder), the electrical polarity depending on the direction of rotation and ...

  7. Nameplate capacity - Wikipedia

    en.wikipedia.org/wiki/Nameplate_capacity

    Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or gross capacity, [1] is the intended full-load sustained output of a facility such as a power station, [2] [3] electric generator, a chemical plant, [4] fuel plant, mine, [5] metal refinery, [6] and many others.

  9. Direct current - Wikipedia

    en.wikipedia.org/wiki/Direct_current

    This symbol which can be represented with Unicode character U+2393 (⎓) is found on many electronic devices that either require or produce direct current. DC is commonly found in many extra-low voltage applications and some low-voltage applications, especially where these are powered by batteries or solar power systems (since both can produce ...
