random_search_single: Randomize the location of a single turbine

In windfarmGA: Genetic Algorithm for Wind Farm Layout Optimization

Randomize the location of a single turbine

Description

Perform a random search for a single turbine, to further optimize the output of the wind farm layout.

Usage

random_search_single(
  result,
  area,
  runs = 20,
  plot = FALSE,
  max_dist = 2.2,
  terrain = NULL,
  weibull = NULL,
  weibull_src = NULL,
  ccl = NULL,
  ccl_roughness = NULL,
  turbine = NULL
)

Arguments

result	The resulting matrix of the function genetic_algorithm
area	Site polygon (sf, SpatialPolygons, or coordinate matrix). Must be projected in metres.
runs	How many jittered layouts to try per best start. Default is 20.
plot	Draw the random-search layouts
max_dist	A numeric value multiplied by the rotor radius to perform collision checks. Default is 2.2
terrain	NULL (default) follows the GA and reuses result$terrainModel. TRUE downloads only if nothing is stored. A DEM rebuilds the model. FALSE skips terrain.
weibull	NULL follows the GA flag. Weibull rasters are not stored; pass weibull_src (or a speed raster as weibull) again. Giving weibull_src is enough; you do not also need weibull = TRUE.
weibull_src	list(k, a) shape and scale rasters (e.g. Global Wind Atlas combined-Weibull-k / combined-Weibull-A).
ccl	Path to a Corine Land Cover raster when terrain is on.
ccl_roughness	Path to the CLC legend CSV (Rauhigkeit_z column).
turbine	Grid cell ID of the turbine to move. If NULL, the function asks interactively.

Value

Returns a list
