**4. Results**

The ANNs are trained for the first intervals (time 0). Thus, Section 4.1 focuses on assessing the results for the same time interval, which the ANNs are trained for. Section 4.2 focuses on the subsequent multistep forecast intervals. The aim is to verify if the hypothesis that the same ANNs can be used to forecast subsequent multistep intervals successfully even though they were trained for the first interval.
