Modeling of a small distribution grid with intermittent energy resources using MATLAB/SIMULINK

Renewable Energy resources are growing exponentially, demanding for more studies in the field of integration. The penetration of these resources has grown to a level which demands structural and functional changes to the grid system to accommodate variable energy resources resulting in smart grid topology. Behavior of the grid depends upon the type of intermittent energy resources being added, point of coupling impedance and the load distribution along the system. As most of these integration activities take place on the distribution side of power network, it is desired to conduct a comprehensive analysis at the low voltage level. This paper presents the results on modeling and dynamic analysis of a distribution grid system with different levels and types of renewable energy resources using IEEE 34 bus system as a candidate testbed. The complete system is modeled and analyzed using Matlab/Simulink.
