Influence of distributed photovoltaic power generation on distribution network and the design of optimal access scheme

“…When the distributed PV power station is connected to the power distribution network below 10 kV, the peak period of distributed PV power generation will be transmitted to the upper level power grid since the capacity of the transformer station in rural villages is not large, generally from 30 to 200 kVA, and the capacity of the PV connected to the distribution network may exceed the load capacity [8–10]. Then a large number of household PV power generation need to go through the 220 V–380 V–10 kV grid to be consumed, this network is more complex, and the power transmission path may be long, which actually brings trouble to reduce the loss, improve the efficiency of enterprises, line loss management and calculation of the 10 kV and the following distribution system.…”
