Abstract

For continued reliability and stability of the modern power system, the new controls that are designed for it, must be functionally flexible and computationally advanced. In accordance with this realization, this paper presents the design of a coordinated wide-area damping controller (CWADC) that employs a partial state feedback control mechanism for damping inter-area oscillations. For developing the control, an enhanced version of selective modal analysis (SMA) is proposed, which is then combined with a linear matrix inequality (LMI)-based polytope. To ensure robustness of the control, the option of selecting PMU inputs from alternate locations is also explored. A 16 machine, 68 bus test system is used to illustrate the proposed technique, while a 29 machine, 127 bus equivalent model of the Western Electricity Coordinating Council (WECC) system is used to demonstrate its applicability to larger systems.
