A comparative study on the dynamic response of three semisubmersible floating offshore wind turbines

2019

Abstract Currently, there is a great interest to globally develop offshore wind energy due to the greenhouse effect and energy crisis. Great efforts have been devoted to develop reliable floating offshore wind energy technology to exploit the wind energy resources in deep seas. This paper presents a comparative study of the dynamic response of three different semisubmersible floating wind turbine structures. All the three platforms support the same 5MW wind turbine. The platforms examined are: a V-shaped Semi, an OC4-DeepCwind Semi and a Braceless Semi at 200 m water depth. A dynamic analysis is carried out in order to calculate and compare the performance of these platforms. The comparison…

Verification of Numerical Weather Prediction Model Results for Energy Applications in Latvia

2014

Abstract Wind power forecasting greatly relies on wind speed forecasts. Numerical Weather Prediction (NWP) models are a reliable source of meteorological forecasts and they can also be used in wind resource assessment. In this work we carry out the verification of wind speed results from the NWP model Weather Research and Forecast (WRF), grid resolution - 3 km. Results from 172 model runs in May and November 2013 are compared with meteorological observations in 24 stations in Latvia. The model usually predicts wind speed values that are larger than the observed and the diurnal cycle has a large impact on verification results. Verification results obtained by interpolating model results betw…

influence of raw data analysis for the use of neural networks for wind farm productivity prediction

2011

In the last decade wind energy had a strong growth because of cost effectiveness of the technology and the high remunerative of investments. The increase of wind power penetration in power grids, however, makes necessary the development of instruments for prediction of productivity of a wind farm. This paper presents a study dealing with the capability of neural network to forecast short term production of a wind farm by the correlation of wind and energy production data. Available measures of wind parameters were related to productivity data of a real wind farm. Also wind data not strictly related to the site have been used in order to assess their possible influence on the production. Aft…

Potential of New and Renewable Energy in Merauke Regency as the Future Energy

2020

Electricity consumption in Merauke Regency increases every year in line with economic growth and population growth. Meanwhile, fossil energy reserves as fuel for power plants have decreased. To reduce dependence on fossil energy and offset the increase in electricity consumption it is necessary to develop alternative electrical energy sourced from renewable energy. Merauke Regency has great potential for renewable energy derived from biomass, solar, and wind. A study or analysis is needed to be able to estimate the energy potential that can be developed in an area. This study uses data collection techniques and analysis of the potential for renewable energy in Merauke Regency using RETScree…

ENERGY FOR ROMANIA FROM RENEWABLE RESOURCES

2012

The European Union admits the fact that energy is essential, for the development of the European economy, but that it also constitutes a challenge, due to the impact on climate change. In Romania, as well as in all the countries of the European Union, which have chosen to promote renewable energy, governments have come up with support frameworks for investors in this field. In Romania’s case, the option for green schemes and compulsory quotas was selected, meaning that each energy producer, which produces renewable energy, receives a number of green certificates for each MW produced, depending on the technology it uses. The price of such a green certificate varies between 27 – 55 Euros. The…

A Cost–Benefit Based, Parametric Procedure to Screen Existing Irrigation and Municipal Supply Reservoirs for Wind Energy Storage

2018

Pumped hydro storage (PHS) is one of the more suitable energy storage technologies to provide bulk storage of intermittent renewable energy sources (RES) such as wind. Since the main limiting factors to the expansion of this mature technology are environmental and financial concerns, the use of an existing reservoir can help mitigate both types of impacts. In addition, the high number of reservoirs for municipal and irrigation supply in many areas of the world makes the idea of using PHS as a relatively diffuse, open-market, technology for RES management attractive. These arguments in favor of PHS must, however, be convincing for investors and regulators from an economic standpoint. To this…
