get_dist_angles: Calculate distances and angles of possibly influencing...

In windfarmGA: Genetic Algorithm for Wind Farm Layout Optimization

Description

Calculate distances and angles for a turbine and all it's potentially influencing turbines.

Usage

get_dist_angles(t, o, wnkl, dist, polYgon, plotAngles = FALSE)

Arguments

t	A data.frame of the current individual with X and Y coordinates
o	A numeric value indicating the index of the current turbine
wnkl	The angle from which wake influences are considered to be negligible
dist	A numeric value indicating the distance, after which the wake effects are considered to be eliminated.
polYgon	A shapefile representing the considered area
plotAngles	A logical variable, which is used to plot the distances and angles. Default is FALSE

Value

Returns a matrix with the distances and angles of potentially influencing turbines

library(sf)

## Exemplary input Polygon with 2km x 2km:
Polygon1 <- sf::st_as_sf(sf::st_sfc(
  sf::st_polygon(list(cbind(
    c(4498482, 4498482, 4499991, 4499991, 4498482),
    c(2668272, 2669343, 2669343, 2668272, 2668272)))),
  crs = 3035
))

## Create a random windfarm with 10 turbines
t <- st_coordinates(st_sample(Polygon1, 10))
wnkl <- 20
dist <- 100000

## Evaluate and plot for every turbine all other potentially influencing turbines
potInfTur <- list()
for (i in 1:(length(t[,1]))) {
  potInfTur[[i]] <- get_dist_angles(t = t, o = i, wnkl = wnkl,
                                    dist = dist, polYgon = Polygon1, plotAngles = TRUE)
}
