Analysis and Research on Frequency Regulation Operation of 1000 MW Unit with the Assistance of Energy Storage
With the continuous development of new energy sources,the operation mode of power grid is constantly chan-ging.The role of large thermal units gradually transforms into frequency regulation and peak shaving to facilitate maxi-mum absorption and consumption of new energy electricity.This results in significant fluctuations in unit load during nor-mal operation of large thermal units and gradual deterioration of unit indicators.In order to provide rapid respond to load demands of power grid,an actual power plant carried out design and construction of an 18 MW/9 MWh energy-storage-assisted frequency regulation project by comprehensively considering the units'intrinsic characteristics,the plant's geo-graphical characteristics,and the market demands of frequency regulation.This retrofit helps in ensuring grid's safe and stable operation and increasing profit from auxiliary frequency regulation.
