Suitable power transformers for solar farm applications

This paper presents a suitable power transformer for solar farm applications. Losses and economic value of the proposed transformer are compared to those of the standard transformer, for the application to a 1 MW solar farm, to help the solar farm owners select the best solution for their business. In this paper, a power electronics transformer called a Solid State Transformer (SST) is also proposed for the application to the solar farm because of its light weight, small size and varieties of functions. There are no core losses during no operation period which is about 15-16 hours a day.
