Current Situation
According to IEA data, over half of the world’s electricity will come from low-carbon sources by 2030. Renewable energy—led by solar, wind, and hydropower—along with nuclear power, will meet all additional global electricity demand.
United States: Growth in manufacturing (e.g., new large loads from semiconductor production) and electrification of heating and transport.
India: Electricity demand is rising at a robust 6.3% annually.
European Union: New growth driven by the adoption of commercial heat pumps and electric vehicles, with data centers also contributing to growth, despite high energy prices and economic slowdown.
Developing Economies: accounting for a massive 85% of all new global electricity demand, with China alone contributing 54% of that total.
Hydropower and dispatchable thermal power plants will continue to play a vital role in ensuring grid reliability.

Scenario: Wind Power Generation
Direct-drive generators are classified by excitation type into two categories:
● Electrically Excited Synchronous Generators (EESG)
● Permanent Magnet Synchronous Generators (PMSG)
PMSG is the mainstream method.
Due to the intermittency of renewable energy, this approach often incorporates energy storage systems.
Integrated designs are increasingly used in lower-power projects.
Clustered configurations emphasize unified management and grid interaction.
● Doubly-Fed Induction Generators (DFIGs) exhibit poor low-voltage ride-through (LVRT) capability. During voltage fluctuations, they often fail to reconnect automatically after protection trips. Most grid-disconnection accidents in China’s wind farms involve DFIG-based systems.
● The gearbox is one of the main failure sources in the unit.
● The rotor lead-out terminals, slip rings, and carbon brushes represent the three major fault points in the generator.
Configuration-Wind Power Generation (Mode as Supplementary and Backup Power Sources)
Battery Energy Storage: The most common solution, including lithium-ion and lead-acid batteries. They enable rapid charging and discharging, absorbing surplus energy and releasing it during generation shortfalls to smooth power output and stabilize frequency.
Supercapacitor/Flywheel Storage: Ideal for handling fast, short-term power fluctuations and delivering instant power support.
Compressed Air Energy Storage (CAES): Used for long-duration, large-scale storage, though less common in small-scale applications.
