Since the early 1990s, open access (OA) scholarly publishing has become widespread in the international scientific community. Although there are numerous benefits of OA publishing, researchers experience a number of disadvantages related to the transition to the OA model. Article processing charges (APCs) paid by authors/institutions have become a key mechanism for funding full OA (the gold OA model). This paper addresses the issue of OA publication costs and attempts to find out what financial resources have been used by researchers at the University of Zagreb, faculty of electrical engineering and computing for publishing in gold OA journals over the last five years. The published OA articles indexed in the Web of Science Core Collection for the period from 2016 to 2020 were analysed. A quantitative analysis of Journal Citation Reports metrics for 163 journals was conducted to identify a relationship between APCs and journal rankings. In addition, a detailed study of gold OA articles was carried out by examining the websites of 31 publishers and identifying APCs for 64 journals. Funding and collaboration models were extracted for 174 gold OA articles as they provide insight into the extent of national funding in relation to financing based on international collaboration. Finally, a calculation of invested funds over the last five years is presented.

Given the area of their research, the students of the faculty of electrical engineering and computing (FER) need the latest scientific information from both domestic and foreign journals. That is why the Croatian Ministry of Science, Education and Sports has provided them with the access to various databases of scientific and technical journals. Furthermore, the faculty of electrical engineering and computing is a provider of one of the most important databases for engineers - IEEE Explore. Students can access these databases either from their homes or from the faculty premises; they can also attend seminars on information retrieval. The goal of this article is presenting the research on students of the faculty of electrical engineering and computing, their usage of available databases and their familiarity with the search tools for those databases.

Electricity price forecasting plays a vital role inthe strategy decision making for almost all power marketparticipants. This article investigates statistical background andpotential relations between different power market products (***-ahead prices, intraday prices, etc.). Danish and Croatianpower markets are used for the purpose of the case studyto present the methods used in this article. First, Danish andCroatian power market structures are shortly explained to clarifythe context of the problem. The data collection and preprocessingmethods are described, followed by the core focus of the study:statistical analysis. In addition to the presented histograms ofrespective power market components, we examine interrelationships through statistical analysis, demonstrating significantcorrelations both numerically and graphically. Furthermore,price spreads are investigated as a logical next step of the noticedcorrelations. Our comparative analysis of Danish and Croatianmarket peculiarities reveals three key findings: i) statisticallysignificant relationships between specific market components,ii) distinct behavioral patterns among observed factors, and iii) anopen-access analytical tool with accompanying dataset for futureresearch. Finally, the findings of this article present to marketparticipants an efficient tool to adjust business strategies andincrease profit.

This paper deals with reduction of losses in electric power distribution system through a dynamic reconfiguration case study of a grid in the city of Mostar,Bosnia and *** proposed solution is based on a nonlinear model predictive control algorithm which determines the optimal switching operations of the distribution *** goal of the control algorithm is to find the optimal radial network topology which minimizes cumulative active power losses and maximizes voltages across the network while simultaneously satisfying all system *** optimization results are validated through multiple simulations(using real power demand data collected for a few characteristic days during winter and summer)which demonstrate the efficiency and usefulness of the developed control algorithm in reducing the grid losses by up to 14%.
