*4.2. Cases Studied*

In this paper, three different cases studied are performed for each system, and these cases are described as follows:

Case 1: this is considered the basic system condition without adding DGs units.

Case 2: in this case, the MG is operated without considering the optimal control settings of BGs, WT, and PV with daily load variations.

Case 3: this case develops the optimal operation of the MG with optimal control settings by using the EO algorithm for BGs, WT, and PV, simultaneously with considering the daily load variations.
