Abstract
This invention presents a method of novel nonlinear control for designing Static Synchronous Compensators (STATCOM). A passivity-based approach is proposed for designing robust nonlinear STATCOM controller. The mathematical model of STATCOM will be represented by an Euler-Lagrange (EL) system corresponding to a set of EL parameters. By employing the Park's transformation, the differential geometry approach is used to investigate the power system dynamics with considering STATCOM under the synchronous d-q frame. The energy-dissipative properties of the proposed model derived in the synchronous d-q rotating frame are fully retained. This model also consider the dynamic response of the changable load. Finally, the passivity-based control is employed by using energy shaping and damping injection techniques to produce the proper control signals for Voltage Source Converter. So that the system embedded with STATCOM is more robust and stable.
