6 FAQs about [Solar photovoltaic power generation regional distribution]

Do distributed PV systems predict regional power?

For the distribution network with large-scale distributed PV access, it is more important to predict the regional power of the total output of multiple distributed PV systems in a certain area.

What is the regional distribution of photovoltaic power stations in China?

In general, the regional distribution of photovoltaic power stations in China is quite different, and the regional competition patterns are variable. Provinces with high installed photovoltaic power stations and high regional competition are mainly located in Northwest and North China.

Is there a short-term regional distributed PV power forecasting method based on sub-region division?

Therefore, this paper proposes a short-term regional distributed PV power forecasting method based on sub-region division considering spatio-temporal correlation. Firstly, the representative power plant is selected after dividing the sub-region by the AP clustering algorithm.

How accurate is the spatial distribution of rooftop PV power generation potential?
