Nonlinear control for static VAR compensator

A nonlinear control design approach based on differential geometric control theory is presented briefly. It is taken the nonlinearity of a power system with static VAR compensator (SVC) into account by the mathematical model of the system for the SVC controller design. The SVC nonlinear control strategy thus obtained is implemented by purely local measurements. The effects for enhancing the stability and dynamic performance of a power system by using the SVC nonlinear control law is illustrated by simulation on a one-machine infinite-bus system. It manifests the validity and the significant advantages of the design approach proposed.<>
