Abstract

As distributed generation (DG) has been deployed in radial distribution networks, it changes their steady-state and transient behavior. To analyze the potential impact of DG on the distribution network, this study models a distribution network enhanced by the DG system, particularly the photovoltaic (PV) system, in the Digital Simulation and Electrical Network Calculation Program (DIgSILENT) and the Open Distribution System Simulator (OpenDSS). As a first case study, this study initially examines load models, voltage regulators, and single- and three-phase transformers provided by DIgSILENT and OpenDSS, adds a single-phase PV system to the IEEE 37-bus test feeder, and compares steady-state power-flow solutions of the IEEE 37-bus test feeder calculated by DIgSILENT to those calculated by OpenDSS. As a second case study, this study also models sufficiently complex feeders, or feeder J1 with the number of 3,434 buses. The test distribution network developed in DIgSILENT will be used in various fields for analyzing the steady-state or transient behavior of DG-enhanced distribution systems.
