In this study, the potential of batteries to increase transformer efficiency is revealed. It is aimed to maximize the transformer efficiency depending on the demand and the installed power of the transformer. Based on this aim, optimization algorithms that can decide on the optimal battery size are developed. The daily charge-discharge cycle of the battery within the scope of transformer efficiency is explained. According to the pilot site studies carried out, up to 22% efficiency increase potential is discovered in a transformer with the battery. Considering this potential, the use of batteries to support transformer efficiency is recommended as a new local service concept.enginfo:eu-repo/semantics/restrictedAccessConference paper51251600085405640008810.1109/GPECOM55404.2022.9815695Grid-size battery usageMixed-integer quadratic programmingOptimal battery sizingTransformer losses2-s2.0-85134874954
