Number of distributed generation (DG) plants integrated to utility network increases due to rising of electricity consumption. DG plants have a big impact on voltage level of network in accordance with this increasing. Especially DG plants based on renewable resources may cause voltage rise and drop because of their intermittently energy generation. Generally, the voltage level is regulated by reactive power control technique and On-load tap changer (OLTC). Generally, HV/MV transformers use OLTC to regulate the voltage level under load. The conventional voltage control techniques depend on current of branch at the main substation end. If the rising of DG installation is taken into consideration, the conventional methods can be inadequate. Artificial intelligence techniques can be used to mitigate this problem. In this paper, an Artificial Neural Networks (ANN) model is designed for determination of OLTC best tap position. ANN model is trained by using different values of network voltage level, DG generation values and amount of load demand. Designed model is applied on electrical network of Selcuk University. The electrical network of Selcuk University is modeled by using PSCAD/EMTDC. 1MW Photovoltaic (PV) power plant is determined as DG plant.

The journal is currently an open access journal.
The articles receive both rigorous peer-review and expedited online publication.
The journal encourages young researchers to submit their unpublished papers.
The authors retain their article’s copyright.
The authors retain publishing rights without restrictions.
Thus, authors may use their own articles for the following non-commercial purposes without asking our permission (and subject only to acknowledging first publication in Journal of Communications Technology, Electronics and Computer Science and giving a full reference or web link, as appropriate).
Authors cannot submit a manuscript for publication to other journals simultaneously. It is a waste of valuable resources because editors and referees spent a great deal of time processing submitted manuscripts. It is also unethical to republish similar research articles (text/figures/tables) again because journals have limited page space and it most likely violates copyrights which have already been transferred to the first journal. Therefore, all journals require a signed author's copyright transfer agreement stating the originality of the research work submitted through a manuscript. As stated above that authors should submit original, new and unpublished research work to the journal. The ethical issues such as plagiarism, fraudulent and duplicate publication, violation of copyrights, authorship and conflict of interest are serious issues concerning ethical integrity when submitting a manuscript to a journal for publication.
The contents of papers are the sole responsibility of the authors, and publication shall not imply the concurrence of the Editors or Publisher.
