Overview of Mechanism and Suppression Method of Transient Over Voltage in Distributed New Energy Access
摘要
Abstract
The high randomness and strong volatility caused by a large number of distributed new energy connected to the grid will lead to transient over voltage behavior in the distribution network,which is one of the chronic problems in the development of distributed energy.The author summarizes the transient o-ver voltage in the distributed new energy grid-connected access system,summarizes the over voltage suppression methods,and analyzes the transient over voltage mechanism in the distributed new energy ac-cess system,including power change,asymmetric fault,operating frequency and resonance.On this ba-sis,the methods of distributed suppression of transient over voltage,including bus regulation and inverter control,are summarized,and the advantages and disadvantages of the suppression methods are pointed out.Finally,the high permeability of distributed new energy and a large number of random load access angles are prospected.The research helps to better understand the transient over voltage problem of dis-tributed new energy access,and provides a reference for the grid connection of distributed new energy.关键词
