Accumulated storage level (energy) — get_storage

Each value represents the energy level at the beginning of the time slot, starting from the provided initial State-of-Charge.

Usage

get_storage_level(
  power,
  init = 0,
  charge_eff = 1,
  discharge_eff = 1,
  time_resolution = 60
)

Arguments

power: numeric vector, being positive when charging and negative when discharging
init: numeric, initial storage level (in kWh, not %)
charge_eff: numeric, charging efficiency (from 0 to 1, default to 1)
discharge_eff: numeric, discharging efficiency (from 0 to 1, default to 1)
time_resolution: numeric, time resolution of the time-series (in minutes)

Value

numeric vector of energy stored

Details

power is interpreted as the grid-side battery power: positive when the grid is charging the battery, negative when the battery is supplying the grid. Pass charge_eff / discharge_eff to convert grid-side power to actual stored energy (grid draws power / charge_eff when charging; storage releases |power| / discharge_eff when discharging).

If power is already storage-side (e.g. from add_battery_optimization()), call with the default efficiencies of 1.
