Local and primary controls of a multi-terminal HVDC grid in an experimental setup

This paper focuses on the experimental implementation of local and primary controls for MT-HVDC in a real test bench (P
nom
= 6 kW). A local control with two different time scales, one for the current and the other for the voltage, and primary control (droop control), which is responsible to vary the reference voltage when a disturbance appears in the network, are addressed in this paper.
