Evaluation of Solar Power Plant Integration Effects on Medium Voltage Distribution Networks Using DIgSILENT Power Factory

Abstract

The integration of large-scale solar power plants (SPPs) into distribution networks brings significant technical challenges related to voltage profiles, reactive power balance, short-circuit currents, and protection coordination. In this study, the effects of adding two SPPs with capacities of 1.6 MW and 16 MW to a pilot feeder in the Diyarbakır region are analyzed using the DIgSILENT Power Factory software based on real grid data. The scenario-based analysis evaluates critical parameters such as power flow, voltage deviations, reverse power flow, and the expected impact on short-circuit levels. The results show that higher generation capacities contribute positively to voltage stability and load balancing but may require adjustments to relay settings and breaker capacities to maintain protection reliability. This study provides a practical framework for planners and operators considering similar renewable integrations in medium-voltage distribution grids and emphasizes the need for comprehensive protection and fault analyses in future work.
