Abstract

This paper presents three phase Distributed Generations (DGs) model in unbalanced three-phase distribution power-flow and analyzes their effect when they are connected in distribution networks. The DGs can be modeled as a voltage-controlled node (PV node) or as a complex power injection (PQ node). The unbalanced threephase distribution power-flow has been developed on the basis of the symmetrical components. Newton Raphson method has been chosen for well known excellent convergence characteristics. The three-phase power-flow program has been tested using a practical 37 node distribution feeder. The solution of the base case of the 37 node feeder is compared with the radial distribution analysis package (RDAP). Then the three-phase power-flow method is used to analyze distribution networks with DGs. The analysis is carried out with various size, quantity and location of DGs. The simulation results show that the integration of DG into an existing distribution network can improve the voltage profile as well as reduces the total system losses.
