This advantage allows for applying VSC-based HVDC in weak systems and removes the need for additional reactive compensation from harmonic filters and other reactive voltage
A SSSC operated without an external Electric Energy source as a Series compensator whose output Voltage is in quadrature with, and controllable independently of, the line current for the purpose of increasing or decreasing the overall reactive Voltage
drop across the line and thereby controlling the transmitted active power.

In larger systems, grid support features such as fault ride-through and reactive voltage
support will make it more desirable for utilities and grid operators to integrate PV into the electric grid.
