Uncertainty is the possibility of deference in real and forecasted values due to a lack of information [34]. This uncertainty in MG may be in operational parameters or in economic parameters. The operational parameters include the quantity of power generated and the quantity of power consumption. On the other hand, the economic parameter includes the effects on economic aspects such as production cost, financial growth and rate of interest, etc. [35].

The uncertain parameters can be predicted in various time ranges that are of the very small time period, a few minutes to a couple of days, which is called prediction of short term. In the prediction of mid-term, the time range is from several weeks to a few months. And in the prediction of the long term, it ranges from few months to several years [36]. The MG problems are considered for hourly intervals, so short term prediction is the best method for this.
