Wider wind-solar complementarity would mean less need for storage
The scientists said, although solar and wind complementarity may not solve structural challenges, it could help reduce the need for energy storage and grid enhancement.
Accelerating energy transition towards renewables is central to net-zero emissions. However, building a global power system dominated by solar and wind energy presents immense challenges. Here, we demonstrate the potential of a globally interconnected solar-wind system to meet future electricity demands.
Couto and Estanqueiro have proposed a method to explore the complementarity of primary wind and solar resources and the demand for electricity in planning the expansion of electrical power systems.
The intermittent nature of wind and solar sources poses a complex challenge to grid operators in forecasting electrical energy production. Numerous studies have shown that the combination of sources with complementary characteristics could make a significant contribution to mitigating the variability of energy production over time.
Han et al. have proposed a complementarity evaluation method for wind, solar, and hydropower by examining independent and combined power generation fluctuation. Hydropower is the primary source, while wind and solar participation are changed in each scenario to improve power system operation.
