Gird-connected Photo-Voltaic (PV) systems rated as 5-10 kW level have advantages of scalability and energy-saving, so they are very typical for small-scale household solar applications.
The Chinese National Development and Reform Commission has published Strategy to Revolutionize Energy Production and Consumption (2016–2030) (No. 2795) , which has proposed to further develop the renewable energy with the grid-connected technologies.However, the inherent uncertainties in weather-driven renewable power sources
The intermittent nature of energy acquired from solar PV array poses a challenge for the researchers and power generating industries to provide uninterrupted power supply.
If we want more new energy consumed, we must consider the systemic nature of electricity, that is to develop the new energy power system. First, it is critical to strengthen technological innovations such as power prediction and control technology to enhance the predictability and controllability of the new energy power generation.
For China, some researchers have also assessed the PV power generation potential. He et al. utilized 10-year hourly solar irradiation data from 2001 to 2010 from 200 representative locations to develop provincial solar availability profiles was found that the potential solar output of China could reach approximately 14 PWh and 130 PWh in the lower
