Influence of PV Access on Power Quality and Predictive Control of Distribution Network SAG Area
This paper mainly studies the influence of photovoltaic access on power quality and predictive control of distribution network sag.Firstly,the influence factors of sags,such as sags amplitude,sags duration and sags,are analyzed,and the influence of different access capacities and locations of distributed photovoltaic on the superposition of power quality and sags is analyzed.Secondly,the range of fault point is discussed,and the critical distance of fault point is calculated by simulation to reduce the range of fault point.Finally,in order to evaluate the effect of distributed photovoltaic access on the prediction results of the distribution network sag,the different factors of the sag area were superposed to obtain the accurate prediction results.
