Dynamic Simulation of Distribution Power Systems with Distributed Renewable Generation

The increased quantity and installed capacity of renewable energy generation at the distribution power system and their impact in the behavior of such network becomes a very relevant topic for planning and operating the grid. It is expected that the number of these distributed facilities continue to grow. By consequence, it is important to simulate and analyze the dynamic performance of the distribution network with Distributed Generation Units (DGs). This paper presents an example of a MATLAB/SIMULINK and RT-LAB-based dynamic simulation of an unbalanced distribution system and the integration of DGs. The IEEE 37 Node Test Feeder has been modified by connecting three DGs at different buses and by modeling the consumption with dynamic load profiles. The objective is to analyze this benchmark and the convenience of individual models of DGs and of the load to evaluate the dynamic performance of the system.
