Coordinated voltage control

Definition

Coordinated voltage control is a strategy used in power systems to maintain voltage levels within desired limits by adjusting reactive power resources in a synchronized manner. This technique is crucial for ensuring the stability and reliability of the grid, especially as renewable energy sources are integrated, which can lead to fluctuations in voltage levels. By effectively managing reactive power and voltage across multiple devices and locations, coordinated voltage control helps optimize performance and enhances the overall efficiency of the electrical network.
