Dynamic Correction Method for the Electricity Load Guarantee Supply Capacity of Thermal Power Units

Scientific dynamic evaluation of the power load supply capacity of thermal power units is crucial for the safe and economic dispatch of the power grid. This article constructs an evaluation index system for the power load supply capacity of thermal power units. A dynamic evaluation and correction method for the power load supply capacity of thermal power units is proposed based on entropy weight method, analytic hierarchy process, and differential theory, and case calculations are conducted using basic data from three thermal power units. Research has shown that for every 0.1 increase in equipment reliability indicators, the average power supply capacity increases by 1.2 - 3.5 percentage points. And optimizing coal quality indicators by 0.2 units can increase power supply capacity by 3.9 - 6.8 percentage points. The work done in this article has certain reference value for improving the power guarantee capability of thermal power units.
