Electric Vehicle Charging

Optimize an electric vehicle charging station using epl.EVs.

Control a number of EV chargers to charge a number of charge events.

Chargers are configured by their size given in charger_mws.

A charge_event is a time interval where an EV can be charged. This is given as a boolean 2D array, with one binary digit for each charge event, interval pairs.

Each charge event has a required amount of electricity charge_event_mwh, that can be delivered when the charge_event is 1. The model is constrained so that each charge event receives all of it's charge_event_mwh.

Optimize two 100 MWe chargers for 4 charge events over 5 intervals:

import energypylinear as epl

electricity_prices = [-100, 50, 30, 50, 40]
charge_events = [
    [1, 0, 0, 0, 0],
    [0, 1, 1, 1, 0],
    [0, 0, 0, 1, 1],
    [0, 1, 0, 0, 0],
]

#  2 100 MW EV chargers
asset = epl.EVs(
    chargers_power_mw=[100, 100],
    charge_events_capacity_mwh=[50, 100, 30, 40],
    charger_turndown=0.1,
    electricity_prices=electricity_prices,
    charge_events=charge_events,
)
