Amplitude-Sequence Decoupling Analysis Method for Evaluating Fluctuation Characteristic of Synthesized Multivariant Power Waveforms
摘要
Abstract
The power system with high proportion of renewable energy is the unique choice to achieve goals of carbon emission peak and carbon neutrality.Because the wind and photovoltaic power generations are all with large fluctuation range and difficult to be adjusted,the power balance mechanism of"source tracing load"will be no longer applicable in the future power system with high proportion of wind and photovoltaic power,and it will turn into a new power balance mechanism of"active power tracing passive power".As the main components of the passive power,the power waveforms of wind,photovoltaic and load are multifarious,and the differences of spatio-temporal distribution are obvious.Analyzing the fluctuation characteristics of the total passive power waveform is the key to achieve accurate assessment of adjustment ability.The traditional analysis methods focus on the study of power distribution characteristics of waveforms,which is difficult to directly study the sequential characteristics of power waveforms.An analysis method of amplitude-sequence decoupled waveform is proposed,which characterizes the waveform through two attributes:"amplitude"and"sequence".On this basis,the concept of the synthesized multivariant power waveforms is proposed,and an amplitude-sequence decoupling model is established for the relationship between the amplitude-sequence characteristics of synthesized multivariant power waveforms and the amplitude-sequence characteristics of each component waveform,which reveals the influences of the amplitude-sequence characteristics of the component waveform on the fluctuation characteristic evolution of the synthesized power waveform.The validity of the method is verified by a set of actual data.关键词
