Impact of Distributed Photovoltaic Access on Voltage and Line Loss of Low-Voltage Distribution Networks(Terrace Area)
The impact of distributed photovoltaic(PV)access on voltage and line loss of low-voltage distribution networks(substations)under a new type of power system is investigated.With the promotion of national poverty alleviation work and"double-zero and double-carbon"strategic development requirements,to accelerate the promotion of distributed photovoltaic power in the rural low-voltage distribution network application demand is becoming more and more significant.However,a large number of distributed PV accesses will cause structural changes in the distribution network,thus changing the voltage distribution of the network and line loss management requirements.At present,there are fewer analyses and researches on improving the economic operation efficiency of 380 V/220 V distribution grids after distributed PV access,and the demand for how to build PV poverty alleviation projects and carry out grid adaptation is increasingly urgent.To this end,through the construction of predictive analysis model research combing various types of T-connection mode distributed PV access scenarios on the low-voltage distribution network,and combined with the actual calculation of the case of engineering on the low-voltage distribution network voltage and line loss changes by access to the PV capacity,access to the PV location and the power factor and other factors affecting the extent of the analysis,to reasonably carry out the construction of distributed photovoltaic access projects in the low-voltage power grid to provide theoretical support and guidance.
