The increased concern about the financial losses due to voltage sags and interruptions plus the advancements in power electronics technology have led to the innovation of very fast acting intervening equipment that can mitigate such disturbances. However, the high cost of these custom power devices can offset their technical benefits. In this paper, a procedure is proposed to find a compromised solution that makes technical and financial sense. A case study of an oil refinery in Alexandria, Egypt is considered to illustrate the proposed procedure.
