A framework for technico-environmental optimization of small wind turbines

Abstract

Small Wind Turbines (SWTs) can provide energy access and participate to energy transition by enabling local electricity production at a low environmental cost. However, there is a lack of comprehensive approaches to address the challenge of reducing the electricity footprint of SWT systems. In this article, a technico-environmental framework is proposed to enable the optimization of the environmental footprint of the electricity provided by a SWT system. The compromise between energy harvest and environmental impacts is studied by establishing and coupling life-cycle and energy models taking into account the system configuration (grid-tied, off-grid), design parameters (tower height, battery sizing), the site characteristics (roughness length, wind resource), and the user behavior aspects (load-shifting). For considered scenarios, the results indicate that the tower height that minimizes the footprint of the provided electricity is identical for grid-tied and off-grid systems. It is in the range of 12-24 m for roughness lengths (0.1-0.5 m) and heavily depends on roughness length and wind resource. Interestingly, increasing the load shifting from 20% to 80% could help reduce by a factor two the footprint of the provided electricity in grid-tied configuration. Following these results, some recommendations are proposed regarding the scaling of the tower and the load shifting. Some perspectives are also given to improve the technico-environmental framework. The data and the source codes used in this article are provided on a public repository.
