System impact analysis of photovoltaic (PV) systems interconnected to distribution networks is an essential task prior to the installation of these systems. Thus, the main purpose of this paper is to establish a standard system impact analysis procedure for PV systems interconnected to distribution networks. First, the PV system structure and related interconnection guides for distributed energy generation systems were discussed in detail. Second, a Taipower distribution feeder in the southern region of Taiwan was employed as the sample system, and a 406 kW PV system was interconnected to its secondary feeder. Then, the system impact analysis was accomplished using theoretical analysis, and simulation and rigorous calculation under the OpenDSS framework. Finally, the outcomes are useful for the distribution engineer and related study to realize the system impact of the PV systems interconnected to distribution networks.
