  2. Unit commitment problem in electrical power production

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

    generation is distributed across a vast geographical area (e.g., a country), and therefore the response of the electrical grid, itself a highly complex system, has to be taken into account: even if the production levels of all units are known, checking whether the load can be sustained and what the losses are requires highly complex power flow ...

  3. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

    An important factor that influences tariff levels is the mix of energy sources used in power generation. For example, access to cheap federal power from hydropower plants contributes to low electricity tariffs in some states. Average residential electricity consumption in the U.S. was 936 kWh/month per in 2007, and the average bill was US$100/month

  6. Load duration curve - Wikipedia

    en.wikipedia.org/wiki/Load_duration_curve

    A load duration curve (LDC) is used in electric power generation to illustrate the relationship between generating capacity requirements and capacity utilization. A LDC is similar to a load curve but the demand data is ordered in descending order of magnitude, rather than chronologically. The LDC curve shows the capacity utilization ...

  7. Energy economics - Wikipedia

    en.wikipedia.org/wiki/Energy_economics

    Energy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. [1] Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. [ 2 ]

  8. Electric power industry - Wikipedia

    en.wikipedia.org/wiki/Electric_power_industry

    The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the ...

  9. Merit order - Wikipedia

    The economic dispatch problem can be thought of as maximising the economic welfare W of a power network whilst meeting system constraints. For a network with n buses (nodes), suppose that S k is the rate of generation, and D k is the rate of consumption at bus k .
