Power-system automation is the act of automatically controlling the power system via instrumentation and control devices.Substation automation refers to using data from Intelligent electronic devices (IED), control and automation capabilities within the substation, and control commands from remote users to control power-system devices.
Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.
Each of these devices begins conducting at a specified voltage and will conduct as much current as required to hold its terminal voltage to that specified voltage by diverting excess current from a non-ideal power source to ground, often through a relatively low-value resistor to dissipate the excess energy. The power supply is designed to only ...
A subsystem of a computer or other electronic device that turns electric power from a wall plug or batteries into a form suitable for use by the system. power-system automation The implementation of power-operated switching and control that allows automatic operation of power system elements, instead of manual operation. power-system protection
Adaptive voltage scaling is used to address the energy-saving requirements of application-specific integrated circuits, microprocessors and system on a chip circuits. It is also well-suited for high-volume systems such as data centers and wireless base stations, as well as power-constrained applications such as portable devices, USB peripherals ...

A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
