There are different technologies for reactive power compensation, these includes; Capacitor Bank, Series Compensator, Shunt Reactor, Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), and Synchronous Condenser.
Fast acting device for reactive power compensation gives better results of voltage regulation in system but at the same time they increase system compensation cost much. On the other side, static compensator has very low cost but alone cannot be suitable for reactive power compensation in system.
In the past, rotating synchronous condensers and fixed or mechanically switched inductors or capacitors have been used for reactive power compensation. Today, static Var generators employ thyristor-switched capacitors and thyristor-controlled reactors to provide reactive power compensation.
The static synchronous compensator (STATCOM) that is usually defined as self-commutated or static VAR compensator is a voltage source converter (VSC) based on controllable switches to control the reactive power Q continuously. Furthermore, STATCOM is shunt connected to the utility grid or system at the point of common coupling (PCC) .
For deciding the optimize participation of static and dynamic compensators, number of samples for reactive power generation from fixed capacitor and STATCOM are developed satisfying Eq. ( 52) by gradually increasing reactive power generation through fixed capacitor and decreasing reactive power generation through STATCOM.
But, as soon as the disturbances occur in IHES at t = 1 s, FC alone is not capable to support the system for this dynamic compensation requirement. On the other side, if cost of compensation is not a constraint for adopting reactive power compensation method, STATCOM can alone be used for providing reactive power compensator.
