In this paper, the performance of voltage-source

converter-based shunt and series compensators used for load

voltage control in electrical power distribution systems has been

analyzed and compared, when a nonlinear load is connected

across the load bus. The comparison has been made based on

the closed-loop frequency response characteristics of the compensated

distribution system. A distribution static compensator

(DSTATCOM) as a shunt device and a dynamic voltage restorer

(DVR) as a series device are considered in the voltage-control

mode for the comparison.
