Wind power and photovoltaic green power generation

What is the wind and PV power generation potential of China?

The wind and PV power generation potential of China is about 95.84 PWh, which is approximately 13 times the electricity demand of China in 2020. The rich areas of wind power generation are mainly distributed in the western, northern, and coastal provinces of China.

Should solar PV be integrated into existing wind power plants?

Furthermore, the results of this study suggest that the integration of solar PV into existing wind power plants, although increasing the overall renewable capacity, it maintains the forecast errors in the range of the values previously observed in the wind power plants, and, in some cases, could enable to reduce the forecast errors.

How much power is generated by solar and wind power?

The annual cumulative power generation of wind and PV power reached 978.5 billion kWh, up 35% year-on-year, accounting for 11.7% of the total power generation, an increase of 2.2 percentage point over the previous year (Fig. 1). 3. Policies of integrated development in solar and wind power generation

Are wind power and photovoltaic power generation complementary in time?

Thus, wind power and photovoltaic power generation are complementary in time. In the hybrid power generation cluster, integrated energy complementary power generation can effectively improve the new energy consumption capacity of power system [ 30 ].

What is the power-use efficiency of PV and wind power plants?

By considering the flexible power load with UHV and energy storage, the power-use efficiency for PV and wind power plants is estimated when the electrification rate in 2060 increases from 0 to 20%, 40%, 60%, 80% and 100% (a) and the power generation by other renewables in 2060 increases from 0 to 2, 4, 6, 8 and 10 PWh year −1 (b).

How are PV and wind power plants estimated?

The installed capacity (a) and costs (b) of PV and wind power plants built during 2020–2060 are estimated in our model by optimizing the construction time of individual power plants at a temporal interval of 5 years (bars) or 10 years (stars).
