Knowra Load balancing Load balancing Load balancing is the coordination of electricity supply and demand to keep the power system operating reliably, despite changing consumption and generation.
Grid frequency control : The regulation of power-system frequency by adjusting generation and controllable demand to match electricity use. Frequency signals an immediate mismatch between supply and demand.
Electric power system : The interconnected generators, transmission networks, distribution networks, and controls that produce and deliver electricity. Load balancing coordinates the operation of this larger system.
Ancillary services : Grid services beyond energy delivery that support reliability, including frequency regulation and operating reserves. Balancing is delivered through several services procured by grid operators.
Electricity load forecasting : The estimation of future electricity demand using historical data, weather, and other predictors. Forecasting anticipates demand; balancing corrects actual mismatches.
Electricity reliability : The ability of an electric power system to deliver electricity continuously and within required quality limits. Effective balancing helps prevent frequency excursions and supply interruptions.
Automatic generation control : A control system that adjusts generator output to correct frequency deviations and scheduled power exchanges. It continuously corrects imbalances after fast frequency response.
Alternating current : Electric current that periodically reverses direction, used in most power grids. Grid frequency is the rate at which alternating current cycles.
Renewable energy integration : The incorporation of variable renewable sources, such as wind and solar, into electricity systems. Weather-driven output changes increase forecasting and balancing needs.
Unit commitment : The optimization of which power-generating units should be started or stopped over a future planning period. Commitment plans which plants are available, while balancing handles operational deviations.
Power outage : A loss of electricity service to part or all of an electrical system. Severe, unmanaged imbalances can contribute to outages and cascading failures.
