Thus, for the metropolitan area of Amman / Jordan characterized by a strong increase in electrical energy demand, the effects of selected variants of such an installation strategy of decentralized PV / PVT systems is assessed in detail. Additionally, for the various PV / PVT installation variants a DC power flow analysis focused on the degree of capacity utilization of the most important transmission lines providing electricity for the metropolitan area of Amman / Jordan is carried out. The results show a positive impact for higher installed electrical capacities of decentralized PV / PVT systems related to the capacity utilization of the existing lines. In this context, PVT systems lead to more efficient overload reductions than PV for the investigated case.en1995-666520192131140Journal ArticleOther
