Review on Frequency Regulation Technology with High Wind Power Penetration

doi:10.11930/j.issn.1004-9649.202003132

Abstract

Abstract: In recent years, the global wind power penetration rate has continued to increase, and wind turbines have gradually replaced traditional synchronous units, which is one of the main reasons that cause power system frequency regulation difficulties and affect grid safety. By upgrading the control design, wind power can provide rotational inertia and frequency regulation capabilities, turn damage into benefits, and improve system frequency safety. Combined with the frequency regulation time scale, this paper details the principles and characteristics of each control method of wind turbine participation in frequency regulation, and analyzes the advantages and disadvantages of different methods and the adaptation process. The influence of high penetration caused by wind power grid integration on the frequency stability of the power system is analyzed. In combination with many recent power system frequency safety accidents involving wind power, it is pointed out that many countries and regions have raised the wind power frequency regulation technology standards. Finally, it is proposed that in-depth research should be conducted on issues such as technical and economic evaluation, market and access, in order to promote wind power to play important role in future power system frequency regulation.

Key words: wind power, frequency regulation, control strategy, energy storage technology, coordination control
