ROBUST LOAD FREQUENCY CONTROL IN A DEREGULATED ENVIRONMENT: A g-SYNTHESIS PPROACH

An approach based on u-synthesis tools Is proposed for the design of robust load frequency controller for eclectic power system In deregulated environments. The system is modeled as a collection of Independent distribution companies supplied by Generation companies either directly or trough transmission companies. The distribution companies are responsible for trackIng the load and hence they are in charge of the Load Frequency Control problem. Connections between distibution companies and the rest of the rest of the system are taken as disturbances. An example is given to illustrate the proposed approach. The resulting controller is shown to minimize the effect of disturbances and achieve acceptable frequency regulation.
