Facing the dual demands of sustainable energy development and environmental protection, how to realize the multi-energy compatibility and optimal allocation of comprehensive energy has gradually become the focus of the energy industry. The diversity and intelligence of energy allocation and increasingly serious environmental impact promote the development of plant and control models in a more complex manner. Modelica is an advanced acausal, object-oriented modeling language in the world. It can easily realize the modeling of complex energy system across different fields. With Modelon hydro power library, thermal power library, Dassault wind power library and ClaRa Plus library, SIMTEK can provide plant and control models modeling and simulation services, development of distributed energy network system model, smart city multi-energy comprehensive utilization solutions and professional technical consult services to meet the different demands of customers.
Comprehensive Utilization of Multi-type Energy Resources in Smart Cities
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.
