Zhang Jianhua pointed out that as the installed scale of wind power photovoltaic power generation continues to expand, the role played in energy supply is becoming more and more obvious. First of all, wind power photovoltaic has become the main body of new installed capacity in China. According to statistics, in 2022, the new installed capacity of wind power photovoltaic accounted for 78% of the new installed capacity in the country; Second, photovoltaic power generation has become the main body of new power generation in China. In 2022, the new wind power photovoltaic power generation accounted for more than 55% of the country's new power generation. Third, the role of wind power photovoltaic power supply is becoming more and more obvious. According to the dispatching data of the power grid company, the average output of wind power photovoltaic power generation in most areas of the country in 2022 accounts for about 15% of the average electricity load, and up to 40%. During the summer peak in 2022, the average output coefficient of photovoltaic power generation in Jiangsu, Shandong, Zhejiang and other large installed provinces reached 0.5 during the noon peak electricity consumption, which strongly supported the energy security supply.
