Abstract

It is expected that increasing amounts of distributed generation (DG) will be connected to the power system in the future. Advances in technology, deregulation in the market and the changes brought about by the government in many countries to end the monopoly of the vertically integrated power utilities led to the birth of this new technology. The other incentive being the alternative energy sources which are becoming more cost effective. Although there are many advantages with the interconnection of the DG into the network, there are many problems that it brings with its interconnection. There are many issues to be considered for the interconnection of DG?s, like the sizing and siting of the DG. The size and site of the DG will have an effect on the voltages and operations of the distribution power system. Since it is necessary that the voltages be within a specified limit, this problem of the siting and sizing of the DG has taken top priority. This thesis discusses a procedure for evaluating the impact of the site, size of the DG and also a change in the loading conditions of the system before and after the reconfiguration of the system due to the fault. This contingency analysis work is validated using the I 13 and I 37 node distribution feeder. Many feasible combinations of the size and site of a DG are analyzed, which resulted in large number of data, while the load flow is run for each feasible combination. The results and trends are presented.
