Horizontal line of photovoltaic power generation support

Why is it important to assess photovoltaic power generation potential in China?

Clear spatial dislocations between PV power generation potential and population distribution and electricity demand. Accurate assessment of the photovoltaic (PV) power generation potential in China is important for the reduction of carbon emission intensity and the achievement of the goal of Carbon Neutral.

Which horizon is used for forecasting a photovoltaic power plant?

The forecast cycles of medium- and long-term forecasts are classified as days and weeks ahead. These kinds of approaches are primarily employed for photovoltaic power plant operation in maintenance and management control [28, 29, 30]. Table 1 shows the type of horizon widely used for forecasting.

Can photovoltaics be installed on the roof of HSR stations?

Mounting photovoltaics (PV) on the roofs of HSR station houses and platforms can potentially provide electricity for high-speed trains, change the energy mix, and reduce emissions. Therefore, it is crucial to assess the technical potential and economic environmental performance of PV for the HSR infrastructure.

Which power grid is most suitable for PV installations?

At the same time, the available land area of the Northwest Power Grid far exceeds other power grids are approximately equal to the sum of the available land area in other regions. In summary, the Northwest Power Grid is most suitable for installing PV facilities, especially the centralized PV facilities that require a large amount of land.

Should centralized PV power generation continue to receive subsidies?

If energy storage technology, cross-regional power allocation, and energy complementation can effectively improve the problems of transmission difficulties and the massive loss of light in these regions, then centralized PV power generation in these regions should continue to receive subsidies or other policy supports.

What is the share of PV and wind in power supply?

The share of PV and wind in power supply increases from 12% to 59% during 2021–2060 at an annual rate of 1.8%, 1.4%, 1.0% and 0.7% in the 2020s, 2030s, 2040s and 2050s, respectively, which requires acceleration relative to an annual rate of 1% for China in the 2010s 40.
