Abstract
The aim of the present work is to assess the electricity production coming from an offshore wind farm that may operate in the northern part of the Romanian coastal area. In the first part, a complete description of the Romanian energy sector is presented considering the t ime interval from January 2008 to December 2018. In general, the elect ricity sold is negat ive (exports exceed imports), with the ment ion that a significant cont ribution comes from hydroelect ric and coal generat ion. It is important to ment ion that , if one of these two sectors willno longer perform on full capacity, the elect ricity balance will be shifted to the elect ricity imports. As for the wind energy, the average values from the vicinity of Sulina site may vary between 5.6 m/s and 8 m/s depending on the season, these results being reported at a wind turbine level (80 m). By using an offshore win d farm which replicates the Greater Gabbard project (504 MW), England, was possible to est imate the annual energy product ion and to indicate the expected impact on the energy sector. For example, a single wind farm may cover 1.7% of the total production, which may be further associated with 9.6% from nuclear, 7.6% from hydroelect ric or 6.4% from coal, respectively.
Highlights
The renewable energy sources represent an important part of any energy market, being possible at this mo ment to implement smart energy systems in order to develop a sustainable future [1]
Th is is located at appro ximately 23 km offshore fo r which correspond a water depth of 32 m, all these characteristics replicat ing the conditions reported by the Greater Gabbard wind farm fro m England
The expected benefits that may occur from the imp lementation of an offshore wind project near the Sulina site (Ro mania – north) was evaluated
Summary
The renewable energy sources represent an important part of any energy market, being possible at this mo ment to implement smart energy systems in order to develop a sustainable future [1]. Ro mania is located in such region, being defined by 245 km of coastline facing the north–western part of the Black Sea. Co mpared to some other renewab le sources, the evolution of onshore wind is visible, starting fro m 1.32 MW in 2005 and being expected a 4000 MW for the year 2020. Regarding the electricity coming fro m fossil fuels, more precisely fro m coal production, we can see that as in any other countries, the Ro manian electricity market is heavily supported by this sector. The impact of the restructuring measurements performed in the min ing sector in 2012, w more v isible in 2016 when the production was reduced with almost 39% and 49% in the case of the lignite and bituminous coal, respectively
