eprllib: use EnergyPlus as an environment for RLlib

This repository provides a set of methods to establish the computational loop of EnergyPlus within a Markov Decision Process (MDP), treating it as a multi-agent environment compatible with RLlib. The main goal is to offer a simple configuration of EnergyPlus as a standard environment for experimentation with Deep Reinforcement Learning.

Installation

To install EnergyPlusRL, simply use pip:

pip install eprllib

Key Features

• Integration of EnergyPlus and RLlib: This package facilitates setting up a Reinforcement Learning environment using EnergyPlus as the base, allowing for experimentation with energy control policies in buildings.
• Simplified Configuration: To use this environment, you simply need to provide a configuration in the form of a dictionary that includes state variables, metrics, actuators (which will also serve as agents in the environment), and other optional features.
• Flexibility and Compatibility: EnergyPlusRL easily integrates with RLlib, a popular framework for Reinforcement Learning, enabling smooth setup and training of control policies for actionable elements in buildings.

Usage

1. Import eprllib.
2. Configure EnvConfig to provide a EnergyPlus model based configuration, specifying the parameters required (see eprllib.Env.EnvConfig).
3. Configure RLlib algorithm to train the policy.
4. Execute the training using RLlib or Tune.

Example configuration

# Import the libraries needed.
import ray
from ray.tune import register_env
from ray.rllib.algorithms.ppo.ppo import PPOConfig
import eprllib
from eprllib.Env.MultiAgen.EnvConfig import EnvConfig, env_config_to_dic
from eprllib.Env.MultiAgent.EnergyPlusEnv import EnergyPlusEnv_v0

# Configure eprllib.
BuildingModel = EnvConfig()
BuildingModel.generals(
    epjson_path=‘path_to_epJSON_file’,
    epw_path=‘path_to_EPW_file’,
    output_path=‘path_to_output_folder’,
)
BuildingModel.agents(
   agents_config = {
       ‘Thermal Zone: Room1’:{
           ‘Agent 1 in Room 1’: {
               ‘ep_actuator_config’: (),
               ‘thermal_zone’: ‘Thermal Zone: Room 1’,
               ‘actuator_type’: 3 ,
               ‘agent_id’: 1,
       },
   }
)

# Start a Ray server.
ray.init()

# Register the environment.
register_env(name="EPEnv", env_creator=lambda args: EnergyPlusEnv_v0(args))

# Configure the algorith and assign the environment registred.
algo = PPOConfig ( )
algo.environment(
    env = "EPEnv",
    env_config = env_config_to_dict(BuildingModel)
)
algo.build()

# Train the policy with Tune.
tune.Tuner(
    'PPO',
    tune_config=tune.TuneConfig(
        mode="max",
        metric="episode_reward_mean",
    ),
    run_config=air.RunConfig(
        stop={"episodes_total": 10},
    ),
    param_space=algo.to_dict(),
).fit()
