Multiple SVS system for voltage regulation by using direct self tuning regulator

Voltage control in power system is done by regulating voltage at desired level by using reactive power compensators. The compensator performance is depending on the power system. To overcome this drawback adaptive control technique can be used. Here direct self tuning approach is designed with multiple static var system (SVS). The concept of direct self tuning voltage regulator is presented in which least square estimation technique is adopted for parameter estimation. Control technique is developed with the help of self tuning library. The aim of direct self tuning regulator is to regulation of the voltage at desired level in the presence of load variation.
