Abstract

Aligned with international trends, fluctuating renewable energy generation is planned to be continuously increased in the Chinese electricity market. For existing power plants, representing integral parts of the electricity infrastructure as well as large financial investments, this results in a demand for optimization and potential re-design. Transient power plant models based on first-principle physical equations have proven to be an efficient tool to investigate process and control system adaptions to prepare field testing and implementations. This paper will give insights into first-principle, component-based modeling using the open standard programming language Modelica. A comprehensive system model of a Chinese reference plant will be presented. The model will be used to simulate off-design transient scenarios for fast load response activation such as primary frequency controls to illustrate how the model-based approach can be used to develop control strategies. In addition, the same model will be used to demonstrate scenarios of component failures that can be used for the development of risk mitigation strategies.
