Pulverized coal-fired power plants are increasingly operated cyclically for the compensation of fluctuating load in the electric grid caused by intermittent production of wind and solar power plants. Dynamic simulation is a powerful tool for investigating the transient behavior of a power plant that is operated cyclically. New solutions, e.g. process changes and control strategies can be tested with a computer-aided dynamic simulation software. This paper introduces a model and dynamic model validation of a commercial pulverized coal-fired power plant that is used in grid load compensation. The model is developed using dynamic simulation software Apros, and it includes all the main processes and control loops of the plant, but also some significant simplifications have been made compared to the real plant process. The model is validated against measurement data from the plant. Simulated dynamic validation cases include typical load changes that are used in grid load compensation. The model can be used for further investigations regarding flexibility and controllability of the plant.
