An automatic procedure for power oscillation dampers design of FACTS devices

In this paper, a procedure is presented to the design of supplementary oscillation controllers installed on FACTS devices. The power system and controllers are modeled in the linearized state-space, and the control problem is formulated through a set of linear and bilinear matrix inequalities, which are solved through the V-K iterations algorithm. The algorithm also presents the possibility of fixing the control structure as a design criteria. Tests were performed in a modified version of the IEEE two area benchmak power system, and include a comparison of fixed and non-fixed structures design, as well as results using an efficient computation through a dedicated computer. The results show that the proposed automatic procedure helps control specialists in enhancing the design of oscillation dampers in a fast computational tool, specially when efficient computing is performed.
