Abstract :
This paper proposes the frequency control scheme for a stand-alone hybrid power system in presence of different controllers. The hybrid isolated power system consists photovoltaic (PV) system, micro hydro power system (MHP), diesel engine generator (DEG) and fuel cell system. Assuming that power produced from PV and MHP system remains constant during a load disturbance. A case study on the impact of FC operation in the frequency control of the integrated renewable power system has been carried out with PI and PID controllers. The hybrid system has been analyzed in MATLAB /Simulink environment with step load demand. A comparative evaluation of frequency deviation for proposed hybrid system in presence of different controlling techniques reflects the improvement in frequency stability in the presence of PID controller as compared to PI controller.
