ECE Master Project - Scalable Network-Based RL Environment for High-Level EV Natural Disaster Response Simulation
In situations of natural disasters/phenomenons, blackouts can occur. To combat this, EV (electric vehicles) drivers can use their vehicles as batteries for customers/ clients. To simulate the difficulty of this challenge of getting to as many customers as possible until the blackout period is over, a RL environment was created. This environment features random scenarios based on node network size, amount of the houses (can't be larger than node size), blackout data, and housing models to simulate a blackout response in a high level matter.
Example of an random agent in action.
Load represents the power needed at the moment from the node.
Current Charge represents the power the agent (or car) has.
Values on edges represents the miles of the edge cost to go through.
Blue node represents buffers. Green node represents homes. Grey node represent blackout out node.
More details can be found in Action & State Space section.
Clone the project
git clone https://github.com/Natemen96/ECEMasterProject.gitGo to the project directory
cd ECEMasterProject/RL python main.pyWARNING: This is a large install (~2GB) and will take approximately 30 mins depending on internet speed. Depending on your set up, you may find it easier to install the package yourself. The list can be found in the conda_env folder. See 'conda_env/rl_window.yml' for the most up to date package list. Works best on Windows.
For easy installing, using a conda first make sure you have conda installed.
After conda is installed do the following to set up the environment
conda env create -f conda_env/rl_window.yml --name rl_env #or any name you prefer
conda activate rl_env #verify it work make sure to run the program within the conda env.
Housing Data can be download from pecan street/dataport
Start at "Home" (a node) travel to each location in exchange for power (main resource for EV), unload power in exchange for reward, travel back to home in exchange for power. The agent can restore power at "Home" and earn more reward depending on how much power it got back. The more power it restores for itself the more it's rewarded.
Once power is restored in a node with a power charging station, the agent can restore energy there as well. Some nodes will be empty depending on parameters.

(0/6. 1/6 ... 6/6 0/6 ...) sample]. Defaults to 6.BasicAgent: Basic Agent that act as skeleton for other agent. Won't work by itself.
Args:
car ([dict]): [car information in the form of a python
dictionary. Required dict information: model, make, year,
avg_energy_consumption(kWh/mile), battery_capacity(kWh)]SmartQLAgent: Smart Agent that uses Qtable to make decisions
Args:
car ([dict]): [car information in the form of a python
dictionary. Required dict information: model, make, year,
avg_energy_consumption(kWh/mile), battery_capacity(kWh)]
sample_rate (int, optional): [decides how often a sample of the
qtable is taken. If left to default it's every 1/100 of total ep]
. Defaults to 100.
qtabletraining (bool, optional): [Flag for turning qtable
training on]. Defaults to True.
quiet (bool, optional): [Flag for turning data collection on].
Defaults to True.RandomDataAgent: Used for data collection of random agent. Doesn't
use Observation.
Args:
car ([dict]): [car information in the form of a python
dictionary. Required dict information: model, make, year,
avg_energy_consumption(kWh/mile), battery_capacity(kWh)]Reward given for unloading, recharging. Diversity of power restoration will result in more reward. Reward lost for running out of energy. Episode is over when EV is out of energy or network is completely powered.
Each Agent will have 24 actions per ep by default.
e+2 Actions:
e - Move (at cost) to Node if possible
1 - Unload (at cost)
1 - Recharge (no cost, expect an action)
2*n + 6*n + 300*n + c States:
n - Statuses of Each Node
Key - Assignment
0 - Buffer (Blue)
1 - Blackout (Darkgrey)
2 - Blackout with Solar (Lightgrey)
3 - Powered (Blue)
4 - Charging Station (Yellow)
5 - Home (Green)
n - Cost of each edge
n - Is the path reachable or not?
0 - No
1 - Yes
c - Charge State (400 possible values by default)
where n is the number of nodes states, e is the number of edges, and c number of is Charge states Each nodes was designed to be based on a house dataset. Some houses that are solar powered will need less power from EVs compared to non-solar powered homes. The cost of house node can be derived from the housing data.
Percentage of blackout based on texas blackout data, as well as change per day.
At a minimum a Q-Learning was used to find the best solutions.
Can be scaled to multiple EV (MARL would be needed), & a larger network. MARL has not been fully tested and is likely very buggy.
During a test run of 50k Eps the smart agent that was support with Qtables had 263.13% improvement compared to a random agent (that does random actions).
