Abstract:
The whole county photovoltaic (PV) development will have an impact on the voltage level of the distribution network due to high penetration of PVs. Firstly, the mechanism of distributed PV to raise voltage level is explored. Then, based on Monte Carlo simulation, the analysis method of the influence of PV configuration uncertainty on voltage is proposed. Finally, the back/forward power flow calculation is adopted, taking a 10kV 88-node feeder in Jiangsu as an example. The voltage level under the current condition, the voltage level after adding planned PV capacity and the maximum PV hosting capacity are calculated and analyzed, which provides reference for the promotion of whole-county-PV development in China.
