Abstract

With the mature of synchronized phasor measurements technology, developing a phasor measurement units (PMUs) based wide-area damping control system becomes feasible. This paper discusses two practical considerations in the design of a PMU-based wide-area damping control system for power grid inter-area oscillations. The first consideration is the selection of PMU measurements. The second consideration is the selection of PMU data reporting rates. In this work, the synthesis of the damping controller is defined as a problem of mixed H₂/H∞ output-feedback control with regional pole placement and solved by the Linear Matrix Inequality (LMI) approach. A two-area four-machine test system is used to illustrate these issues.
