Nonlinear Control Design of Shunt Flexible AC Transmission System Devices for Damping Power System Oscillation | Science Publications

摘要

> Problem statement: The disturbance in the complicated network of power system may cause in nonlinear response. Static Synchronous Compensator (STATCOM) is a power electronic based device that has the capability of controlling the line current. This study applies the STATCOM to decrease the over line current in power system during dynamic state. Approach: This study proposes the control strategy of a STATCOM to enlarge the stability region of a simple power system. The control is determined very carefully to satisfy the Lyapunov
