Influence of PV Penetration on Distribution Transformer Aging

Banu Uçar, Mustafa Bağrıyanık, and Güven Kömürgöz
Abstract—Increasing power demand urged countries to seek out energy sources with higher efficiency and lower cost than the existing ones. Solar energy is an effective alternative source to the traditional energy sources. The photovoltaic distributed generation is an effective energy source since it combines the advantages of smart grid and solar energy. Depending on the season, photovoltaic generation connected to the distribution network shows different penetration that affects the network load distribution, which can lead to excessive loading at lines, cables and transformers in distribution systems. As the life expectancy of transformers and cables in the distribution system depends on the operating conditions, overloading caused by penetration of distributed photovoltaic systems speeds up the aging of the components. Therefore, investigating the effects of photovoltaic systems on the aging is important for providing insight on the efficient use of components in the distribution transformers. In this study, the impact of loss of life on the distribution transformer photovoltaic production is examined by taking the seasonal influences into account from the point of view of a consumer.

Index Terms—Distribution transformer, aging and photovoltaic generation.
