Simulation and Analysis of Protection Issues in Distributed Generation Integrated Systems using Artificial Intelligent Controllers

In this paper, protection issues that arise due to distributed generation when integrated in the system are discussed. Protection of distribution system with the incidence of distributed generation can be achieved by designing the intelligent controllers that operate both under normal and faulted conditions. To analyze the issues related to protection and the performance of various distributed resources like wind turbines, microturbines, solar, PEMFC and SOFC units are considered in this paper. They are designed and modelled in MATLABSIMULINK environment. The wind power in this model is driven by an induction machine. To analyze deeply the performance of various distributed resources impact under normal and fault conditions a study has been done by simulating the various Artificial Intelligent Controllers. It can be seen from the simulation results that the performance of the DG units under normal and fault conditions is good with the AI controllers like Fuzzy, model reference adaptive controller compared to that of the conventional PID controller.
