6 FAQs about [Solar power generation power attenuation curve]
Can China achieve a 1300 GW solar power capacity target?
As the goal is to explore the minimum cost path for achieving China's cumulative installed solar PV power capacity target of 1300 GW in 2050, the optimal development path may show a stable pattern with little difference in the early stage. The development path is highly dependent on the algorithm and seems a little strange.
Why is China reducing the investment ratio for solar PV power?
To make it competitive enough when competing with traditional power generation forms, and to reduce the fiscal expenditure at the same time, Chinese government has taken a series of measures to weaken the incentive policies in solar PV generation. Thus, the investment ratio for solar PV power is set to be a lower level of 0.5% of GDP.
How important is the proportion of investment in solar PV power generation?
No matter how high the proportion of investment is, when the solar PV power generation exceeds the absorptive capacity of the grids, it is an infeasible solution. Therefore, increasing the proportion of the investment plays a limited role in the development of solar PV power under current situations.
What are the constraints of solar PV?
Constraint (15) is the grid absorptive limitation, which thereby avoids explosive growth. Constraints (16) and (17) mean that the installed capacity of the solar PV power must achieve the target for 2020 and 2030, respectively. The equality constraints (18) represent the cost forecast by the learning curve.
What factors affect solar PV development?
(2) The factors concerning the construction costs, such as the GDP growth rate and investment ratio, have only a limited impact on solar PV power development, but the learning rate, grid absorptive capacity, and carbon permit price are critical factors affecting the development path in the later period.
What is the optimal development path for China's solar PV power?
Fig. 4 shows the optimal development path for China's solar PV power under the base case. The solar PV power development target for 2050 will be achieved in 2048, two years ahead of the schedule. The development trend will be maintained before 2040, but the a big vibration of the installed capacity appears after 2041.
