1. An apparatus of a power flow control unit comprising:
a plurality of capacitors connected in parallel to form a DC capacitor;
at least one liquid cooling block configured to recirculate a liquid coolant; and
at least one high-power switching assembly thermally coupled to the at least one liquid cooling block and electrically connected to the DC capacitor, wherein the power flow control unit is configured to inject at least 1 MVA (mega-volt-amp) of reactive power into a power transmission line.
