This paper presents an application of rule-based proportional integral (PI) controller for the load frequency control (LFC) taking into account the effect of power transmission network. The analysis is carried out considering a six-bus system and genetic algorithm (GA) is used to optimize the gains of conventional as well as rule-based PI controller. The results show that dynamic response of frequency deviation improved significantly using rule-based PI controller compared to conventional PI controller.
