Because of the high integration of electric power, information and business flow in smart grid, it is necessary to have a complete grid infrastructure to promote the development of clean energy, realize the optimal allocation of renewable energy resources, such as hydropower, wind power, solar energy, etc, and improve the operational ability of grid-connected energy. In the modern power system network, there are many unstable factors, and the actual operating conditions are changing at all times. As the power system is complex and nonlinear, the traditional method based on system identification or engineering experience is always limited by the environment, which can't meet the requirements of smart grid any more.
- Development and optimization of distributed multi-energy network model
- Real-time simulation of smart grid
- Health management of smart grid
- Design and development of control system
The smart grid model contains a 400 MW thermal power station, a 50 MW nuclear power station, a 50 MW geothermal power station, a 10 MW solar thermal power station, a 2 MW wind turbine and a 1 MW small hydroelectric power station. Based on the smart grid model, customers can study the frequency fluctuation of the hydroelectric power stations, wind power stations and solar thermal power stations caused by the environmental impact, the large frequency variation caused by the failure of thermal and nuclear power stations and the isolation of transmission lines in geothermal power stations. Besides, the design of power grid control system can ensure the stable operation of power grid.
