Oscillation frequency control based on H/sub /spl infin// controller for a small power system using renewable energy facilities in isolated island

Output power from wind turbine generators occurs a large frequency fluctuation on small power systems. In order to solve this problem, we propose an oscillation frequency control for a new power supply system with using renewable energy facilities in isolated island. The proposed system can supply a high-quality power using aqua electrolyzers, fuel cells, renewable energy, and diesel generators. The feature of proposed system is to use an aqua electrolyzers and fuel cells. The hydrogen generated by the aqua electrolyzers is used as fuel of fuel cells. The simulation results and the efficiency of proposed system are shown in this paper
