Good morning one and all. I recently tried submitting a paper to a Journal. The submission process mandatory required suggesting one reviewer and one oppose reviewer. Is it a norm in Journal submissions? If yes, how should one choose reviewers since I do not personally know any experts in the field? I have been submitting papers to conferences and never found such conditions there. Now my request is could you please help me to find one reviewer and one oppose reviewer in the area of optimal location of distributed generation in radial distribution systems.
