One of the most important criteria for the stability of electrical networks, is the frequency of the voltage produced. This frequency is subjected to the hazards of the load connected to the turbo generator group. Indeed, the balance of the frequency results from the balance between active power produced by the turbo alternator group and power demanded by the load connected to the network. This paper presents a comparative study of three methods of regulation to solve the problem of frequency fluctuations in hydroelectric plants: modified Proportional–Integral–Derivative (PID) control, Internal Model Control (IMC) and Infinite Horizon (H∞) Control. Simulation model in the presence of these has been established in Matlab / Simulink. The results of the simulation have subsequently revealed their robustness, which demonstrates once again their reliability.
