Abstract
To maintain the reliability of power supply, proper functioning of all equipment is necessary. The distribution transformers constitute a major part of a distribution system and its remaining life should be properly investigated. Renewable energy sources are integrated into a distribution system to reduce losses, improving voltage profile and save energy cost. This may affect the life of equipment present in the existing system. In this paper, a practical distribution system with installed rooftop solar photo-voltaic (PV) units is considered for investigation. Total study periods has been divided into three parts. The benefits of PV in terms of the life of the transformers have been quantified for the each part. For PV integration and time-series load flow simulation, MATLAB component objective model (COM) interface of OpenDSS is used. The actual load, load shape, temperature and irradiation data have been collected to prepare input to the simulation model. The results show that there is a considerable decrease in the rate of aging of the distribution transformer.
