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.

In this study, we aim to (1) develop an integrated approach that combines image segmentation and object-based algorithm for extracting PV power stations at 30-m resolution using Landsat time-series images; (2) quantify the temporal and spatial development in PV power stations from 2007 to 2019 and analyze what types of land have been converted .

When the wind is too strong, the sunlight too intense, or the rainfall too heavy, absorption capacity cannot keep up, resulting in wasted wind, solar energy and hydropower. Conversely, power generation would be difficult if the wind is too weak or if there is insufficient sunlight or rainfall.

For instance, photovoltaic power plants in Northwestern China (capacity of 43.87 GW in 2019, 1/3 of China’s total) were punished for providing intermittent energy to the Northwest Grid with.

6 FAQs about [Photovoltaic power generation and energy storage in the northwest are difficult]

Does the spatial distribution of PV power generation potential decrease from northwest to southeast?

The results show that the spatial distribution characteristics of the capacity factor decrease from northwest to southeast, which is basically consistent with the spatial distribution of PV power generation potential.

Why are PV power stations growing so fast?

The rapid expansion of PV power stations within the past few years was mainly driven by national renewable energy policy. However, this rapid expansion of PV power stations also raises many problems such as low utilization and land-use changes.

Why is it difficult to forecast on-site power generation?

It is difficult to precisely forecast on-site power generation due to the intermittency and fluctuation characteristics of solar and wind energy. Solar and wind generation data from on-site sources are beneficial for the development of data-driven forecasting models.

Can photovoltaic energy storage systems be used in a single building?

Photovoltaic with battery energy storage systems in the single building and the energy sharing community are reviewed. Optimization methods, objectives and constraints are analyzed. Advantages, weaknesses, and system adaptability are discussed. Challenges and future research directions are discussed.

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.

Does PV power generation potential affect population distribution and electricity demand?

Meanwhile, there were clear spatial dislocations between the PV power generation potential and the population distribution and electricity demand in China. In areas that accounting for about 75% of the PV potential, population and electricity demand only accounted for about 16% of the total population and total electricity demand in China.
