AI Technical Summary

Problems solved by technology

However, the intermittency, uncertainty, and volatility of solar and wind energy make the output of PV and WT unstable, leading to its uncontrollability
At present, my country's wind power development is concentrated in the "Three North" regions. At the same time, due to the inflexible output of cogeneration units, the problem of wind curtailment is becoming more and more serious, resulting in serious waste and economic losses.
