Abstract
For an AC/DC coupled transmission system, the
change of transmission power on the DC lines will significantly
influence the AC systems’ voltage. This paper describes a
method to coordinated control the reactive power of power
plants and shunt capacitors at DC converter stations nearby, in
order to keep the voltage of the pilot bus tracking its set point
considering the DC system’s transmission schedule change. The
approach is inspired by model predictive control (MPC) to
compensate for predictable voltage change affected by DC side
transmission power flow and the potential capacitor switching at
DC converter stations. The control strategies are calculated
from a multi-step dynamic optimization problem that is solved
by mixed integer quadratic programming method. Time-domain
simulations showed positive results of the proposed voltage
controller.
