voltagecontrol
Voltage control refers to the set of methods and devices used to regulate electrical voltage levels in electrical systems, ensuring voltages stay within specified limits for safe operation and system performance. In alternating-current power systems, the goal is to maintain bus voltages close to their nominal values while minimizing losses and preserving power quality. Voltage control relies on managing reactive power and network impedance through various technologies and control schemes.
Common methods include transformer tap changing (on-load and off-load) to raise or lower voltage at substations,
Control strategies can be centralized or distributed. Voltage measurements feed feedback control loops, which may use
In direct-current systems and microgrids, voltage regulation is achieved with DC-DC converters and regulated DC buses,
