“…Efficient solutions of these complex nonlinear problems are made possible via the fixed-step Generalized-α integrator. Several publications documented the verification studies of the Bladed code performance and accuracy [9,14,15]. Bladed version 4.14.0.3 is utilized in the present studies.…”

“…The early design phases of the turbine designs usually adopt IEC [4] or DNV [5] standards or both, where the incorporation of the farm effects is not taken into account in detailed manner due the dependence on the layout. Despite that, there is a growing need to incorporate the wind farm effects in time accurate simulations in wind turbine design process to enable a correct estimation of the wind turbine loads and performance [6].…”

“…In the present work, an attempt to incorporate the wake effects into the wind turbine design tool Bladed [9,14,15] will be documented. The wind farm effects are extracted from a wind farm solver LongSim [1,16] and these are incorporated into Bladed simulations to obtain time accurate load analyses.…”

A new framework “BladedFarmWake” to include the upstream wake effects into a wind turbine design tool Bladed was developed in the present work. The effects of neighboring turbines in a wind farm are extracted from a wind farm flow solver LongSim, which has been developed for designing wind farm controllers and evaluating wind farm performance, taking account of atmospheric conditions and wake effects including the importance of turbine layouts and individual turbine or wind farm control strategies. These wind farm effects are incorporated into Bladed simulations to obtain time accurate load analyses. BladedFarmWake is designed to work with less human interaction as much as possible, allowing the tool to be adopted in large scale load analyses within the wind turbine design load cases (DLCs). It is demonstrated that the timeseries of the wind flow field and the wake meandering effects are successfully modelled in the framework. The effects of velocity deficit and the wake added turbulence are well captured in the generated turbulent data. As a consequence of the velocity deficit from the upstream turbine, the hub load changes considerably due to the wake meandering effects. The newly developed integrated framework will be of value for wind turbine engineers to incorporate wind farm effects in the design process.

“…The success story of wind energy is inextricably linked to its long history in research and development in many aspects. This includes ongoing efforts spent on improving the reliability of wind turbine designs and site assessments [33]. The design of wind power plants (PLTB) has among others been carried out for the Savonius vertical axis wind turbine type [29]- [32], [34] - [37] and horizontal axis wind turbine [31][36] - [42].…”

Bomo Beach, which is managed by community groups to become a tourist attraction, has the potential for renewable energy in the form of solar and wind energy. This potential can be harnessed and converted into electrical energy. This study aims to design energy education media for solar power plants and wind power plants at Bomo beach, Banyuwangi regency. The design is carried out in accordance with the natural management of tourist beach. The power plant designed is the integration of the solar power plant system (PLTS) and the wind power plant system (PLTB). Solar power plants use solar panels while PLTB uses horizontal shaft wind turbines and vertical shafts. The energy housing is made as a power store with a 12 volts battery. The design results show that the integration design of solar power plants and PLTB can be applied as an energy education media.

This paper presents comprehensive investigations into idling instability occurring on the IEA 15 MW reference turbine. The systematic studies are carried out by means of Blade Element Momentum (BEM) and free wake vortex (Vortexline) methods. Two state-of-the-art dynamic stall models are tested in the present investigations, namely the Beddoes-Leishman and the IAG dynamic stall models, implemented into a development version of the wind turbine design code Bladed. The studies highlight the importance of unsteady aerodynamic modeling to predict idling instabilities and emphasize the characteristics of each modeling strategy. It is demonstrated that the IAG dynamic stall model predicts a more physically reasonable idling instabilities. Furthermore, Vortexline enables the calculations of the induced velocities even under idling conditions in contrast to BEM. The combination of the Vortexline method and the IAG model is considered to provide the most reasonable turbine response. The studies will be helpful for load engineers to select appropriate modeling strategies and shed some light into future engineering modeling improvements of wind turbines.
