  "textContent": "An optimized control method for a primary frequency regulation based on an exergy storage correction of a thermodynamic system of a coal-fired unit is provided. Through measuring and recording temperatures and pressures of working fluids and metal heating surfaces of the coal-fired unit thermodynamic system in real-time, an exergy storage amount of the thermodynamic system is obtained. During a transient process, according to an exergy storage variation before and after acting of each regulation scheme, a maximum power output of each scheme is obtained. Thereafter, through comparing the maximum power output with a maximum power regulation quantity required by a current frequency regulation, an optimal primary frequency regulation control scheme is selected, and a primary frequency regulation control logic is corrected, so as to be high-efficiently and accurately involved in the primary frequency regulation control and maintain a fast and stable grid frequency. The present invention improves a predictive accuracy of an actual effect of the various thermodynamic system regulation schemes and reduces a selection blindness of the primary frequency regulation schemes, so that an operation flexibility of the coal-fired power unit during the transient processes is greatly improved.",
