The electric energy transmission and distribution characteristic by AC current is the real power with reactive power. The control on the reactive power of the AC power system has been achieved by the use of Flexible alternating transmission system devices like Thyristor Controlled Reactors (TCR), Static Synchronous Series Compensator (SSSC), STATic COMpensator (STATCOM), and Unified Power Flow Controller (UPFC). The sources of VAR have the disadvantages of slow response, reduced voltage ampere reactance support in fault conditions and High coast of STATCOMs Because of the large DC/AC inverters and High levels of energy storage.
