当考虑到发电机报价曲线的影响时，发电计划偏差优化问题是一个高维、离散、约束条件复杂的非线性最优化问题。

Considering the generators bidding prices curves, the generation scheduling error optimization problem is high dimensional, disperse, complex constrained, non-liner problem.

超短期负荷预测结果与原有的发电计划之间难免出现偏差。

The deviation between ultra short term-load forecast and the original generation plan is unavoidable.

考虑到超短期负荷预测偏差的情况下，以购电费用变化量最小为目标函数重新调整发电计划，从而导致电网可用输电能力(atc)发生变化。

Because of super short-term load forecast error, ATC is changing with the adjustment of the generation scheduling by the object function that purchasing charge is least.
