Currently, the automatic generation control（AGC） frequency modulation technology for the combination of thermal power unit and energy storage system is booming in the power industry of China. This study introduces the basic principle, the typical scheme, control process and practical engineering effect of this technology. And the impact of energy storage system access on the electrical system of thermal power units and the selection of energy storage batteries are discussed. In addition, the investment and profit of the engineering application of this technology are analyzed. The results show the AGC frequency modulation technology for the combination of thermal power unit and energy storage system has a significant effect and good economic benefits. And the energy storage system access has basically no effect on the control system and the electrical system of thermal power units. Besides, lithium iron phosphate battery has advantages as a battery of energy storage system. This study provides a reference for engineering application of the AGC frequency modulation technology for the combination of thermal power unit and energy storage system.
