Based on the findings from our previous research, we have identified an exceptionally unique self-enhancing mechanism within the process of technology catch-up in China's PV industry. This mechanism is a positive feedback loop among three key variables: R&D effort, government subsidies, and domestic demand.
With the increased integration of PV generators into the grid, the system operators start to require PV generators have capabilities to stay online during the fault, and provide the active power and the reactive power supports when being required to do so.
Indeed, the installed capacity of grid-connected PV generators in China has ranked the first in the world since the end of 2015, and still shows a strong growing trend (Ding et al., 2016, Kang and Yao, 2017, National Energy Administration of the People's Republic of China, 2019).
R&D efforts are the underlying logic of China's photovoltaic industry technology catch-up. The unexpected success of China's PV industry in technology catch-up has been noted. However, existing research has overlooked the multidimensional nonlinear complexities in its underlying mechanisms.
By controlling the instantaneous three-phase inverter output voltages , and , the PV generator controls the active power output and the reactive power interchanges with the external grid.
There are two typical configurations of PV generator in power system applications, namely, single-stage and two-stage as shown in Fig. 1a, Fig. 1b. A single-stage PV generator uses only one converter to complete both the maximum power point tracking (MPPT) and the power grid connection.
