Series Capacitive Compensation
Series capacitive compensation method is very well known and it has been widely applied on transmission grids; the basic principle is capacitive compensation of portion of the inductive reactance of the electrical transmission, which will result in increased power transfer capability of the compensated transmissible line.
The Need for Reactive Power Compensation
Reactive power compensation in a power system is of two types—shunt and series. Shunt compensation can be installed near the load, in a distribution substation, along the distribution feeder, or in a transmission substation. ... The difference in how series and shunt capacitors regulate the voltage and reactive power flows.
Series compensation goes the distance
In places like South America series compensation is proving a very cost-effective way of increasing capacity and maintaining stability in long distance transmission corridors - avoiding the expense of new lines.

Reactive Power Role and Its Controllability in AC Power Transmission …
The above expression shows that an ideal line (with zero resistance) loaded at its surge impedance loading does not produce or consume reactive power, so it will have the same voltage at both ends. When a line is loaded above its SIL, it acts like a shunt reactor which are absorbing the reactive power from the system, and when a line is …
