Integration of distributed generation into distribution networks introduces new challenges to distribution system operators while the penetration level increases. One of the challenges is the voltage rise issue as a part of the steady-state analysis of DGs during planning and operational stages. This issue should be analyzed in order to determine the hosting capacity of distribution feeders in the first instance. Accordingly, Turkey is a promising candidate to integrate high penetration of DGs and has recently started to publish regulations for DGs. This paper presents a method to calculate DG hosting capacity of MV distribution feeders in Turkey. The presented calculation is compared with the current regulations in terms of load flow results. Additionally, this paper aims to ease the technical reviews of the DG integration with the presented method, which helps to assess the steady-state voltage impacts introduced by DGs. Finally, a general flow chart of steady-state analysis is proposed for Turkish DSOs.
