loadFactor {antaresProcessing}R Documentation

Load factors of clusters

Description

This function computes the load factor and other related statistics for cluster of a study.

Usage

loadFactor(
  x,
  timeStep = "annual",
  synthesis = FALSE,
  clusterDesc = NULL,
  loadFactorAvailable = FALSE,
  opts = NULL
)

Arguments

x

Object of class antaresData created with function readAntares. It must contain hourly detailed results for clusters and has to contain the columns minGenModulation.

timeStep

Desired time step for the result.

synthesis

If TRUE, average surpluses are returned. Else the function returns surpluses per Monte-Carlo scenario.

clusterDesc

A table created with the function readClusterDesc. If is this parameter is set to NULL (the default), then the function attempts to read the needed data in the same study as x.

loadFactorAvailable

Should loadFactorAvailable be added to the result?

opts

opts where clusterDesc will be read if null based on data

Value

a data.table of class antaresDataTablecontaining the following columns:

area

Area name

cluster

Cluster name

mcYear

Only if synthesis=FALSE. Id of the Monte-carlo scenario

timeId

Time id and other time variables

loadFactor

Load factor of the cluster. It represent the proportion of the installed capacity of a cluster that is effectively generate

Formula: production / (unitcount * nominalcapacity)

#'

loadFactorAvailable

Load factor of the cluster. It represent the proportion of the capacity available of a cluster that is effectively generate

Formula: production / thermalAvailability

propHoursMinGen

Proportion of hours when production is positive and all units of a cluster are either off, either producing at their minimum. This situation occurs when units are kept producing above the optimal level to avoid future startup costs or to satisfy the constraints generated by parameters "Min. up Time" or "Min gen. modulation".

Formula: mean(1 if production > 0 and production = max(min.stable.power * unitcount, minGenModulation * nominalcapacity * unitcount) else 0)

propHoursMaxGen

Proportion of hours when all units started produce at their maximal capacity.

Formula: mean(1 if production > 0 and production = NODU * nominalcapacity * (1 - spinning / 100))

Examples

## Not run: 
# data required by the function
