  2. Ancillary services (electric power) - Wikipedia

    en.wikipedia.org/wiki/Ancillary_services...

    Ancillary services are specialty services and functions provided by actors within the electric grid that facilitate and support the continuous flow of electricity, so that the demand for electrical energy is met in real time. The term ancillary services is used to refer to a variety of operations beyond generation and transmission that are ...

  3. Demand response - Wikipedia

    en.wikipedia.org/wiki/Demand_response

    Economic demand response is employed to allow electricity customers to curtail their consumption when the productivity or convenience of consuming that electricity is worth less to them than paying for the electricity. Ancillary services demand response consists of a number of specialty services that are needed to ensure the secure operation of ...

  4. Virtual power plant - Wikipedia

    en.wikipedia.org/wiki/Virtual_power_plant

    Virtual power plant. A virtual power plant (VPP) is a system that integrates multiple, possibly heterogeneous, power sources to provide grid power. [1] A VPP typically sells its output to an electric utility. [2][3][4][5][6][7] VPPs allow energy resources that are individually too small to be of interest to a utility to aggregate and market ...

    In addition to Day-Ahead and Real-Time markets, MISO operates an ancillary services market that began on January 6, 2009. This market provides energy and operating reserves and regulation and response services supporting reliable transmission services. [12] The name was changed in April 2013.

  6. Vehicle-to-grid - Wikipedia

    en.wikipedia.org/wiki/Vehicle-to-grid

    Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles (PEVs) sell demand response services to the grid. Demand services are either delivering electricity to the grid or reducing the rate of charge from the grid. Demand services reduce the peaks in demand for grid supply, and hence reduce the probability of disruption from ...

  7. Electricity market - Wikipedia

    en.wikipedia.org/wiki/Electricity_market

    A simple "energy-only" wholesale electricity market would only facilitate the sale of energy, without regard for other services that may support the system, and experienced problems once implemented alone. To account for this, the electricity market structure typically includes: [7] ancillary services not

  8. Power system operations and control - Wikipedia

    en.wikipedia.org/wiki/Power_system_operations...

    Power system operations is a term used in electricity generation to describe the process of decision-making on the timescale from one day (day-ahead operation[1]) to minutes [2] prior to the power delivery. The term power system control describes actions taken in response to unplanned disturbances (e.g., changes in demand or equipment failures ...

  9. Voltage control and reactive power management - Wikipedia

    en.wikipedia.org/wiki/Voltage_control_and...

    Voltage control and reactive power management are two facets of an ancillary service that enables reliability of the transmission networks and facilitates the electricity market on these networks. Both aspects of this activity are intertwined (voltage change in an alternating current (AC) network is effected through production or absorption of ...
