Study on Active Frequency Control for Large-scale Grid Connection of Photovoltaic Power Plants
With the transformation of global energy structure and the demand for sustainable development,the large-scale grid connection of photovoltaic(PV)power plants has become an important development aspect in power system.Howev-er,the grid-connected operation of PV generations also brings a series of technological challenges,among which active fre-quency control is a key issue.Therefore this work conducts in-depth study on methods of active frequency control for large-scale grid connection of PV sources from three aspects:constructing large-scale PV generation arrays,establishing PV ar-ray circuit models under different shadow modes,and actively controlling grid connection frequencies.It is expected to fa-cilitate promotion of development and application of PV generation and transformation and sustainable development of en-ergy structure.
