Thermal power generation cost calculation method based on positive balance and negative balance

The invention provides a thermal power generation cost calculation method based on positive balance and negative balance, and the method is characterized in that the method comprises the following steps: carrying out real-time data collection, and obtaining fuel data; establishing a fuel inventory statistical model according to the fuel data, and counting the fuel inventory; real-time coal consumption is calculated in a positive balance mode and a negative balance mode; establishing a cost calculation knowledge base, calculating the evaluation index of each index of the fuel, and distinguishing the fuels with different qualities; and establishing a cost optimization module, optimizing the combustion strategy of the fuel, and generating a thermal power generation cost result and report. The fuel is counted through the fuel stock, the coal consumption is calculated in real time in a positive balance mode and a negative balance mode, and thermal power generation cost optimization is achieved by combining the fue
