Variable-Generation Integration in China: An Update

Wind and solar power represent more than 99% of China's gridconnected variable generation (VG). In recent years, VG power has grown rapidly. At the end of 2018, the cumulative installed capacity of VG was 359 GW, which was 19% of the national total installed capacity (Figure 1). The ge neration capacity of wind and solar power was 184.3 and 174.6 GW, respectively, accounting for 9.7% and 9.2% of the national total installed capacity (Figure 2). As of the end of 2018, the installed VG capacity in 13 provinces, including Qinghai, Gansu, Ningxia, Hebei, and Xinjiang, accounted for more than 20% of their total installed generation capacity.
