In recent years, the increasing electricity demand leads energy operators to new grid investments. On the other hand, electricity grids are constantly extending and include different kinds of generation and consumption sources. In addition, the operating conditions of lines and equipments in the electricity transmission system are changed in consequence of increasing distributed generation resources on the grid. For these reasons, it is required to plan and analyze properly in power system establishments. In this study, the electricity transmission infrastructure of industry regions in Ankara, Turkey is modeled. The usage of large powerful loads, the constantly increasing electricity demand and the increment in microgrid applications are the main reasons for the preference of these industrial areas. In the stage of modeling the electricity transmission system, the actual data of grid, lines, substations and generation plants are used in the DigSilent program. The different case studies depended on load and short-circuit analyses are implemented on the developed grid model. As a result of the conducted case studies, the recent generation and consumption situations, the impacts of microgrids on the existing system and the possible grid reactions for the increasing demand and demand response in future years are evaluated in an effective manner. |
