Wind Farm Layout Optimization Using a Viral Systems Algorithm

2. Previous Work

Renewable energy sources such as wind, solar and biomass, among others have gained importance and several efforts are being made to improve the efficiency of the different renewable energy technologies. When designing a wind farm and analyzing the optimal placement of the wind turbines in the wind farm, the wake and its impact on the power output of the wind turbine has to be taken into account, several models for the analysis of the wake have been developed in the past by many researchers, these models are usually divided into two main categories which are; 1. analytical models (Jensen, 1983, Larsen, 1988; Ishihara et al., 2004) and 2. computational models (Crespo et al., 1999; Crasto and7 Gravdahl, 2008).
