Continuous Lifetime Optimisation of Variable Electricity Resources

CLOVER

CLOVER minigrid simulation and optimisation for supporting rural electrification in developing countries.

CLOVER Quick Start Guide

This guide provides a very brief introduction to get your CLOVER installation up and running as quickly as possible following the initial download. The file structure has two main branches:

• a python branch, src, which contains CLOVER's source code which is used to perform simulations and generate outputs,
• and a data branch, locations, which contains informaiton describing the locations being modelled and contains parameters to outline the simulations and optimisations that should be run.

An example location, "Bahraich," in India, is included in the initial download for reference.

Downloading CLOVER

CLOVER can be downloaded from Github or installed via the Python package manager. If you intend to use CLOVER, but not develop or edit any of its code, then it is recommended that you install CLOVER from the Python package manager as this will guarantee that you install a stable version. If you intend to develop or edit any of the code contained within CLOVER as part of your research, then it is recommended that you download CLOVER directly from Github.

The Python package manager

Installing

To install the CLOVER package, from anywhere on your system, run:

python -m pip install clover-energy

This will download and install the latest version of CLOVER into the current virtual environment that you have running. If you are using Anaconda, please note that this will install CLOVER only for the virtual environment that you are currently in, not for your system as a whole. CLOVER can now be run by calling clover from a terminal anywhere on your system, though you will need to set up a location in order for it to run successfully. See 'Setting up a new location' below.

Upgrading

To update the version of CLOVER that you have installed, from anywhere on your system, run:

python -m pip install clover-energy --upragde

This will fetch the latest stable version of CLOVER and install it into your current virtual environment.

Downloading from Github

To download the CLOVER source code directly from Github, simply click the green Code button near the top of this page, and select Download ZIP. Once downloaded, unpack the zip file into a directory of your choice. You will now be able to run CLOVER from a terminal in this directory. Use the cd command to change the directory of your terminal to the extracted folder in order to run CLOVER.

Setting up your Python environment

CLOVER is a scientific package and, as such, uses Python packages that may not have come installed by default on your system. These packages can be easily installed, provided that you are connected to the internet, either using pip, the python package manager, or conda, a virtual-environment-based system. Instructions for conda are provided below:

Anaconda method

To install using conda, from the root of the repository, run:

conda install --file requirements.txt

Note, on some systems, Anaconda is unable to find the requirements.txt file. In these cases, it is necessary to use the full and absolute path to the file. E.G.,

conda install --file C:\\Users\<User>\...\requirements.txt

Pip install

The CLOVER package is published as an installable package, clover-energy, which can be installed using the python package manage, pip, in the usual way:

python -m pip install clover-energy

This should install all of the relevant dependencies for CLOVER as well as providing three installable executable files: new-clover-location, update-api-token and clover, which are described in more detail below.

Note, installing CLOVER in this way will install the package to your conda environment or local computer and will not provide you with easy access to the source code files. To develop CLOVER and have access to the source code, ensure that you download the code from GitHub.

Setting up a new location

New locations can be set up in one of two ways:

• By creating a new location from scratch and inputting all necessary information. To do this, call the new_location helper script with just the name of your new location:

  python -m src.clover.scripts.new_location <new_location_name>
  

  or, if on a Linux machine,

  ./bin/new_location.sh <new_location_name>
  

  or, if you have installed the clover-energy package:

  new-clover-location <new_location_name>
  

• By basing the location on an existing location. To do this, call the new_location helper script with the --from-existing flag:

  python -m src.clover.scripts.new_location <new_location_name> --from-existing <existing_location>
  

  or, if on a Linux machine,

  ./bin/new_location.sh <new_location_name> --from-existing <existing_location>
  

  or, if you have installed the clover-energy package:

  new-clover-location <new_location_name> --from-existing <existing_location>
  

Updating an existing location

As part of the ongoing development of CLOVER, new features will be introduced. In order to incorporate these into existing CLOVER locations on your system, you can use the new_location script provided to update these locations:

python -m src.clover.scripts.new_location <location_name> --update

or, if you have installed the clover-energy package:

new-clover-location <location_name> --update

CLOVER will search through your location and attempt to replace missing files and include new files that have been brought in by an update. Note, CLOVER will not correct missing or invalid fields within files, these must be corrected manually and the User Guide should be consulted for more information.

Renewables.ninja

Go to https://www.renewables.ninja/register to register a free account to gain your API token. This will be needed in order for CLOVER to correctly fetch and utilise solar profiles.

Once you have created a new location, you can input your API token using a CLOVER helper script:

python -m src.clover.scripts.update_api_token --location <location_name> --token <renewables_ninja_api_token>

or, if you have installed the clover-energy package:

update-api-token --location <location_name> --token <renewables_ninja_api_token>

Completing input files

Within your location folder you will find a subfolder named inputs. This contains the various input files which are used by CLOVER. These need to be completed in order for CLOVER to run. Some files are needed only for optimisations while some are needed for both optimisations and simulations.

Simulation and optimisation files

• Ensure that inputs/generation/generation_inputs.yaml contains your renewables.ninja API token and that the other parameters within the file are set correctly;
• Complete inputs/location_data/location_inputs.yaml with the details of your location;
• Complete the inputs/generation/grid/grid_times.csv template with the details of your location:
  • Grid profiles are a 1x24 matrix of hourly probabilities (0-1) that the grid is available,
  • Input all grid profiles at the same time;
• Complete inputs/generation/diesel/diesel_inputs.yaml with information about your diesel generator;
• Complete inputs/load/devices.yaml with the devices that your location needs and the parameters as appropriate. NOTE: CLOVER considers kerosene as a mitigated source. The best practice for leaving kerosene out of your location is to set the initial_ownership and final_ownership of the kerosene device included by default to 0.
• In the inputs/load/device_utilisation folder, complete the utilisation profiles for each device e.g. light_times.csv:
  • Utilisation profiles are a 12x24 (monthly x hourly) matrix of probabilities that the specified device is in use in that hour,
  • Each device in “Devices.csv” must have a corresponding utilisation profile;
• In the inputs/simulation folder, complete the energy_system.yaml file with the details of your location's energy system;
• In the inputs/simulation folder, complete the simulations.yaml file with the details of the simulation bounds that you wish to run.

Optimisation-only files

• Complete the inputs/impact/finance_inputs.yaml with the financial details of your location;
• Complete the inputs/impact/ghg_inputs.yaml with the GHG-emission details of your location;
• Complete the inputs/optimisation/optimisation_inputs.yaml with the various parameters used to define the scope of the optimisations;

See the user guide, available within the repository, for more information on these input files.

Running CLOVER

The operation of CLOVER can be broken down into two steps:

1. Fetching and generating profiles
2. Carrying out simulations and optimisations as appropriate.

When running a CLOVER simulation or optimisation, profiles will be generated if they are not present. However, these can also be generated on their own, without running a simultaion.

Profile generation

To generate the profiles on their own, run CLOVER with the name of the location only:

python -m src.clover --location <location_name>

or, on a Linux machine:

./bin/clover.sh --location <location_name>

or, if you have installed the clover-energy package

clover --location <location_name>

Running a simulation

When running a CLOVER simulation, the size of the PV and storage systems needs to be specified on the comand-line:

python -m src.clover --location <location_name> --simulation --pv-system-size <float> --storage-size <float>

or, on a Linux machine:

./bin/clover.sh --location <location_name> --simulation --pv-system-size <float> --storage-size <float>

or, if you have installed the clover-energy package

clover --location <location_name> --simulation --pv-system-size <float> --storage-size <float>

where <float> indicates that a floating point object, i.e., a number, is an acceptable input. The number should not have quotation marks around it.

Running an optimisation

When running a CLOVER optimisation, the size of the PV and storage systems are optimised based on the information inputted in the optimisation_inputs.yaml file. To run an optimisation, simply call CLOVER from the command line:

python -m src.clover --location <location_name> --optimisation

or, on a Linux machine:

./bin/clover.sh --location <location_name> --optimisation

or, if you have installed the clover-energy package

clover --location <location_name> --optimisation

Analysis

When running CLOVER simulations, in-built graph plotting can be carried out by CLOVER. To activate this functionality, simply use the --analyse flag when initialising a CLOVER simulation from the command-line interface.
