Abstract:

With the rapid increase in the scale of new energy installations, the role of thermal power units in grid peak regulation has become crucial. Swift and precise prediction of the duration of the “startup-grid connection” process for thermal power units is essential for dispatchers to promptly adjust grid operation status. To address the current reliance on human experience for predicting the duration of the “startup-grid connection” process, this paper proposes a method for predicting the duration of this process for thermal power units. First, the startup-grid connection process of thermal power units is analyzed to identify key operational parameters at each stage. Then, logical calculations are leveraged to predict the duration of the “startup-grid connection” process. Results of a pilot test on a typical unit on the “Net-Source platform” indicate that the proposed model can accurately monitor the response state of the units during the “startup-grid connection” process and successfully predict its duration. This method provides timely decision support for dispatchers, helping to ensure the safety and stability of grid operations.
