Abstract
A general assessment of the wind energy potential from the eastern part of Romania was carried out in this work by taking into account onshore and offshore wind conditions. First, a perspective of the importance of the renewable resources into the Romanian electricity system was provided, from which was noticed that the wind production cover almost 15% from the demand (reported to 2017). From the analysis of the wind data significant differences were noticed between the onshore and offshore regions, the last one presenting more important wind resources, that significantly increase during the winter time (with almost 22%). According to the performance reported by an offshore wind turbine (rated at 3 MW), such generator will operate at full capacity in a maximum 9% from the time, if we consider a hub height of 119 m.
Highlights
The onshore wind energy is one of the most dynamical sectors, being estimated that this is one of the cheapest renewable solutions that can compete at this moment with the conventional generation solutions in terms of the costs [1]
The aim of the present study is to identify the differences between the Romanian onshore and offshore regions and to estimate the performances of some offshore wind turbines that may operate in this coastal sector
It is important to mention that, Romania entered in the European Union (EU) at the beginning of 2007
Summary
The onshore wind energy is one of the most dynamical sectors, being estimated that this is one of the cheapest renewable solutions that can compete at this moment with the conventional generation solutions in terms of the costs [1]. The vast water areas allow the development of large capacity projects, being expected more important wind resources than onshore [2,3,4,5]. The offshore regions seem to be defined by similar wind resources as onshore, the only difference being related to the decision of the developers to assembly larger farms in order to cover the higher costs associated to such projects [6]. Reported to electricity demand, was estimated that almost 12.2% is covered at this moment from the operating wind farms [7]
