Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO039: Investigation of shadow/flickering in operational windfarms in Greece
Konstantinos Gkarakis, Energy Engineer MSc, MA, MBA, University of West Attica
Abstract
In recent years, the size and capacity of windturbines have been increased, which causes more difficulties in their integration into the natural landscape. At the same time, however, the distance between them increases so that there are smaller energy losses between them and their total installation density is reduced. An additional effect is the shadow created by the blades during movement and depending on the sunshine this shadow falls on the ground or on any nearby object. The term "shadow flicker" is used for shadow flickering as "alternating changes in light intensity caused by rotating vanes that cast shadows on the ground on static objects such as a window in a residence." It is a phenomenon that is caused only during the hours when there is sunshine and the position of the sun is low, but nevertheless it makes the daily life of citizens who live or work in areas within the radius of influence of this shading difficult. The research team in this work investigates the induced moving shading in twenty (20) operating wind farms across Greece, with different sized wind turbines (with diameters from 44 - 163m) and draws conclusions on the areas of influence, the hours per year observed, the number of days, the maximum number of minutes of moving shadow in a day in a given area. The aim is to determine the shading created by the wind turbines in wind farms and how it changes in relation to the sizes of the wind turbines, the layout of the wind turbines and the orography. The results of the twenty representative wind farms are evaluated and investigated whether this parameter should now also be controlled in the environmental impact studies and whether the distance of 500m from the nearest settlements that exists today is sufficient.
