turbine_influences: Find potentially influencing turbines

Description

Find all turbines that could potentially influence another turbine and save them to a list.

Usage

turbine_influences(t, wnkl, dist, polYgon, dirct, plotAngles = FALSE)

Value

Returns a list of all individuals of the current generation which could potentially influence other turbines. List includes the relevant coordinates, the distances and angles in between and assigns the Point ID.

Arguments

t

A data.frame of the current individual with X and Y coordinates

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

dirct

A numeric value indicating the current wind direction

plotAngles

A logical variable, which is used to plot the distances and angles. Default is FALSE

Examples

## Exemplary input Polygon with 2km x 2km:
library(sf)

Polygon1 <- sf::st_as_sf(sf::st_sfc(
  sf::st_polygon(list(cbind(
    c(0, 0, 2000, 2000, 0),
    c(0, 2000, 2000, 0, 0)
  ))),
  crs = 3035
))

t <- st_coordinates(st_sample(Polygon1, 10))
t <- cbind(t, "Z" = 1)
wnkl <- 20
dist <- 100000
dirct <- 0

res <- turbine_influences(t, wnkl, dist, Polygon1, dirct, plotAngles = TRUE)
