Participation of electrochemical energy storage in secondary frequency regulation of thermal power units

In recent years, new energy power and other new energy power and other new energy power generations such as wind power and solar energy have led to a large number of thermal generators for a long time to hear heavy AGC regulatory tasks. And more and more pure coagulating thermal units are transformed into a heating unit, this increases grid Frequency adjustment difficulty. With the decline of lithium ion battery costs, the energy storage assisted heating thermomechanical unit involved in frequency modulation has become the best choice for improving the frequency modulation capability of thermal generators. The energy storage assisted heating thermomechanical unit involved in the frequency modulation, which not only improves the load adjustment energy of the thermal power unit, but also enables the unit to obtain more benefits in the auxiliary service market, but also helps the power grid in the new energy power generation, help China to achieve carbon-up peaks and Carbon neutralization. This paper analyzes the characteristics of energy storage and frequency modulation, which introduces the engineering and access to thermal power unit and control strategy. This paper analyzes the characteristics of energy storage participation in frequency modulation, and introduces method and control strategy of energy storage access to thermal power units.
