The present work investigates the performance of the Fantanele-Cogealac wind farm through the application of a neural-network-based modeling approach, aiming to capture the correlations between various meteorological parameters and the performances of a wind turbine. As a first step, the meteorological conditions from the vicinity of this site were evaluated from a statitiscal and seasonal point of view, by considering MERRA-2 dataset covering the time interval 2018-2025. The results are indicated in terms of surf...

The Romanian electricity market has undergone substantial structural transformations during the last decade as a consequence of energy transition policies, increasing integration of renewable energy sources and geopolitical developments affecting European energy systems. The period between 2024 and 2025 represents a relevant timeframe for evaluating the evolution of electricity generation, consumption patterns and the balance between supply and demand within the national energy system. This study provides an asses...

In this study, based on a relatively high resolution wind database (ERA5), an assessment of the nearshore wind conditions in the western part of the Black Sea was conducted. From the reanalysis of the wind datasets provided by the ERA5 product, significant differences between the onshore and offshore wind power were identified, with the offshore regions being more resourceful than the onshore ones. Generally, the appeal of a site for a wind farm project is determined throughout a classification of the wind classes...

The present study's primary purpose is to evaluate and provide a more comprehensive, unbiased and helpful picture of the Romanian energy potential, highlighting the emerging renewable resources. Firstly, several indices are taken into consideration to underline the Romanian energy portfolio structure. The installed capacities and the country's power generation, carbon dioxide emissions, nuclear generation and consumption, and renewables power are among the critical indices used in this project. The data and result...

The wind energy is substantially growing in the last decade, but the biggest challenge remains the prediction of the performances of the wind turbines. The increasing energy demand and climate changes forced us to commit quick decisions and to develop efficient solutions. One of the solutions can be repowering and significant changes in transmission systems to deliver it through the electric grid. Fantanele Cogealac is the largest onshore wind farm in Romania. The wind farm exist since 2012, so in at least 10 year...

Being an almost landlocked sea, the Black Sea has a particular situation regarding water exchange and circulation. Moreover, the anthropogenic pressure and shipping related activities worsen the situation of this sea from the pollution point of view. The introductory part of the article presents the role of the ballast water system onboard ships in a few words. Then, the paper presents the environmental context of the Black Sea with the focus on the wind and waves, factors which can affect the ship stability. The ...

Making marine renewable energy projects in the Black Sea is a subject discussed more and more lately because of the potential of this area. Various studies show that the western part of the Black Sea basin is characterized by high potential from point of view of the wave and wind energy. Because of the favorable wind conditions, offshore wind farm projects can be implemented in this area. In order to make all the maintenance activities in safe conditions, and also the shipping operability between the offshore wind...
