The successful grid connection of a 54-MW/100-kWp wind-solar complementary power plant in Nan’ao, Guangdong Province, in 2004 was the first wind–solar complementary power generation system officially launched for commercialization in China.
At present, most hydro-wind-PV complementation in China is achieved by compensating wind power and PV power generation by regulating power sources, such as a unified dispatch of hydropower and pumped-storage power stations on the grid side.
Hydro–wind–solar complementary energy system development, as an important means of power supply-side reform, will further promote the development of renewable energy and the construction of a clean, low-carbon, safe, and efficient modern energy system.
China has made considerable efforts with respect to hydro- wind-solar complementary development. It has abundant resources of hydropower, wind power, and solar power and shows promising potential for future development.
After hydropower or pumped-storage hydropower regulation, the total output of wind–solar–hydro complementation should have the least volatility, that is, in turn, beneficial to the consumption of wind and solar power in the grid.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually.
