A Load Frequency Control is important in electrical power system design and operation. Due to unexpected large power consumption in industries and other sectors, power deficiency fulfillment is great task to be accomplished for the generation side. So to make counter balance for generation and expected demand, Load frequency control is used. For the reliable operation of a large interconnected power system an automatic generation control (AGC) is required; its main role is to maintain the system frequency and to maintain the tie line flow at their scheduled values during normal period in an interconnected system. The output from conventional methods i.e. performance of the controllers like PI, PID (proportional, integral and derivative and their combination) are studied and compared among different aspects and at the most Fuzzy Logic is proposed to for power system because the limitations of the Conventional controls possess deficiency to optimal value as requisite and variation in load and frequency analysis point of view while handling non-linearity in system. The fuzzy logic controllers found to be better one and it provides almost appropriate dynamic responses over the conventional PI, PID controller. System simulation is realized through numerous matlab-Simulations.
