一种多时间尺度评估新能源弃电的方法及系统
By using a multi-timescale assessment method for renewable energy curtailment, renewable energy curtailment is decomposed into seasonal, inter-day, and intra-day multiple electricity volumes, solving the problem of undecomposed renewable energy curtailment in power system planning and supporting quantitative analysis and absorption issues.

AI Technical Summary
Existing technologies have failed to effectively decompose the situation of renewable energy curtailment in power system planning, which may lead to inappropriate measures and make it impossible to quantitatively analyze the distribution of renewable energy curtailment at different time scales and its dominant factors.
A multi-timescale assessment method is adopted. By acquiring power output data, production simulation is carried out to decompose the abandoned renewable energy into seasonal, daytime, and intraday power volumes. The abandoned renewable energy volume is calculated using monthly power balance and daily power balance.
It enables quantitative analysis of renewable energy curtailment at different time scales, provides support for the absorption problem, and features convenient and fast calculation.
