In an electrical grid, contingency is an unexpected failure of a single principal component (e.g., an electrical generator or a power transmission line) [1] that causes the change of the system state large enough to endanger the grid security. [2]
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 ...
Diagram of an electrical grid (generation system in red, transmission system in blue, distribution system in green) An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric ...
Applying electric power to a process that was previously done by other means, or, development of an electric power system in a region that previously had none. electroactive polymers A polymer that significantly changes size or shape when exposed to an electric field. electrocardiograph A record of the electrical activity of the heart.
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
Balance of plant (BOP) is a term generally used in the context of power engineering to refer to all the supporting components and auxiliary systems of a power plant needed to deliver the energy, other than the generating unit itself.
pandapower is a power system analysis and optimization program being jointly developed by the Energy Management and Power System Operation research group, University of Kassel and the Department for Distribution System Operation, Fraunhofer Institute for Energy Economics and Energy System Technology (IEE), both of Kassel, Germany.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
