The voltage profile of the system can be controlled by either injecting into the system reactive power or absorbing reactive power from the system. Literature review f 2 introduction voltage control in an electrical power system is important for proper operation of electrical power equipment, to prevent damage such as overheating of generators and motors, to reduce transmission losses, and to maintain the ability of the system to withstand and prevent voltage collapse.

In a real power system, voltage instability is caused by a combination of many additional factors which includes the transmission capability of the network, generator reactive power and voltage control limits, voltage sensitivity of the load, characteristics of reactive compensation devices, action of voltage control. In voltage reduces starting torque.
