China”s renewable energy installed capacity has reached the world’s largest scale, and the country is now accelerating its transition from treating renewables as a supplementary source to making them the dominant energy supply — a shift that demands fundamental changes in how power grids operate, an expert said on Saturday.
Wang Weisheng, chief engineer at the China Electric Power Research Institute and director of the State Key Laboratory of Renewable Energy Grid Integration, made the remarks at an academic development lecture held on May 30 to celebrate the annual National Science and Technology Workers’ Day.
Wang pointed out two major challenges brought by the high proportion of renewable energy connected to the grid: ensuring reliable power supply and maintaining stable grid operation. Unlike conventional thermal power, wind and solar generation are inherently variable and weather-dependent, creating uncertainty that traditional grid management systems were not designed to handle.
To address these challenges, Wang outlined two critical technical pathways — precise renewable energy power forecasting and optimized grid-connection control — which together form the backbone of China’s strategy for integrating large-scale renewables into the national power system.
China has made major technical breakthroughs in recent years, Wang added. These include advances in renewable energy output forecasting that reduce uncertainty in generation planning, fault ride-through capabilities that allow wind and solar farms to remain connected during grid disturbances, wideband oscillation suppression technologies that prevent instability in power electronics-dominated grids, and active grid support functions that enable renewable energy plants to help stabilize voltage and frequency.
He emphasized that renewable energy grid integration and control are critical links in the energy transition. Precise forecasting is needed to reduce uncertainty,…
