Abstract :
[en] In this paper, a simplified multi-step recedinghorizon
controller is introduced to control the violations in
transmission voltages and stop developing long-term voltage
instabilities. The system model is derived from the context of
quadratic dynamic matrix control and is represented as a set
of linear constraints derived from sensitivity analysis and bias
terms acting as modelling error corrector. Resulting multi-step
optimization is highly structured convex quadratic programming
problem for which reliable standard codes are available. The
goal of proposed controller is to achieve high performances
with simplified system model relying on reliable optimization
solver. The Nordic32 test system is used for evaluating the
performance of proposed controller and its comparison with
existing closely related approaches focusing on minimization of
expensive controls (load shedding).
