求翻译：当系统中存在大规模风电场或负荷波动较大时，需要考虑风速与负荷的不确定性，在线计算中可适当简化模型，选取风电场出力较预测值减小、负荷突增的不利场景做暂稳校验，从而既能保证较高的计算速度，也能得到更加全面的ATC信息。是什么意思？

When there is a large-scale wind farm or load fluctuations, the need to consider the uncertainty of wind speed and load, on-line calculation may be appropriate to simplify the model, select the wind farm output than the predicted value decreases, the load of the sudden increase in adverse scenes do

When the system existed in large-scale wind farm or load is more volatile, need to be taken into account when the wind speed and load of uncertainty in the calculation, the line may be appropriate to select simplified model wind contribute less than forecast, load sudden increase in the number of su

When in the system exists the large-scale wind electric field or the load undulation is big, needs to consider the wind speed and the load uncertainty, in the online computation may simplify the model suitably, the selection wind electric field output forecast the value reduces the disadvantageous s

When present in the system of mass or load fluctuations in wind farm is a large, need to take into account wind speed and load of uncertainties, may be appropriate to simplify the online calculation model, select more forecast value decrease of wind farm output, load the sudden adverse scenarios do
