Increasing the penetration of wind turbine generations, needs more study about

controlling frequency impacts of power system. Frequency control is changed with

unbalancing real-time system generation and load. ...

, the output feedback method is the

most rational technique with the best dynamic response. Also, with using a reduced-order observer, the dynamic

response of system is improved. In fact, using these methods is necessary for load frequency control...

This paper presents an investigation into the stability

enhancement of LFC problem in one area power system using a

power system stabilizer. A complete system model for lowfrequency

oscillation studies ...

A reduced-order state observer controller, with a pragmatic viewpoint, applied to interconnected

load frequency control problem in a deregulated power system is presented. In the practical

environment, access to all of the state...
