Stand-alone ac power supply system such as isolated islands is subject to large frequency and voltage fluctuations caused by power deviations of wind turbine generator and load demand. The autonomous decentralised frequency control system of parallel operated decentralised generators based on droop characteristic is presented in this study. The conventional droop control methods proposed in past researches...
The output power fluctuation of renewable energy power plants such as wind turbine generator and photovoltaic system result in frequency deviation and terminal voltage fluctuation. Furthermore, these power fluctuations also affect the turbine shafting of diesel generator and gas-turbine generators which are the main power generation systems in isolated islands. This paper presents a control strategy...
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...
Wind turbine generators and PV system causes fluctuating power condition. Therefore, the fluctuating power causes frequency and voltage fluctuations. In order to solve this problem, we propose a new power supply system by using renewable energy power production plant in isolated island. The feature of this system is to use hydrogen production unit and fuel cell. The operation of suggested system absorbs...
