The task of additional reactive power compensation (also known as voltage compensation) is assigned to compensating devices: [7] passive (either permanently connected or switched) sinks of reactive power (e.g., shunt reactors that are similar to transformers in construction, with a single winding and iron core [ 9 ] ).
A unified power flow controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer. [ 1 ]
In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.
This feature can provide controllable voltage compensation. [2] In addition, SSSC is able to reverse the power flow by injecting a sufficiently large series reactive compensating voltage. [2] The SSSC consists of a voltage source converter (VSC) connected in series with the transmission line through a transformer.

These services include reactive power compensation, voltage regulation, flicker control, active power filtering and harmonic cancellation. [6] Wind turbines with variable-speed generators have the potential to add synthetic inertia to the grid and assist in frequency control.
If this is the case, then the load banks used for testing require reactive power compensation. The ideal solution is a combination of both resistive and reactive elements in one load bank package. Resistive/reactive loads are able to mimic motor loads and electromagnetic devices within a power system, as well as provide purely resistive loads.
