Analysis of Harmonic Active Power Characteristics of Distributed Photovoltaic and Wind Power Grid-Connected

This paper analyzes the active power characteristics of common harmonics and ultra-high harmonics of distributed photovoltaic and wind power grids, and explores their different effects on energy metering, which has great guiding significance for achieving more fair and reasonable metering schemes. For the harmonic acquisition data of a wind power grid-connected point, the data characteristic analysis method is used to quantitatively analyze the harmonic characteristics, summarize the variation characteristics of the harmonic energy of the new energy grid-connected, and compare the different characteristics of the common harmonic and the super-high harmonic active power. Provide methodological guidance for the study of its predictive analysis of the impact of energy metering. (paper)
