🔋 Represent energy systems as Python data classes for improved modularity and readability

EnergyDataModel provides an open-source, Python-based data model that enables energy data scientists and modellers to write more modular and readable code. EnergyDataModel lets you:

• 🧱 Modularity - Represent energy assets, energy systems and other relevant concepts as object-oriented building blocks;
• 🏗️ Relationships - Structure your energy assets in graphs and hierarchies representing energy systems that can be serialized to files (e.g. .csv, .json, and .geojson files);
• 👀 Visualization - Visualise energy systems maps, graphs, flows and structure using built-in plotting functions;
• 🤓 Readability - Write more explicit Python code through human-readable expressions and built-in convenience methods;
• 🧩 Interoperability - Convert data format to other energy-relevant data models and ontologies; and
• 💬 Communicate - Communicate effectively in teams with a common energy system data vocabulary.

EnergyDataModel leverages Python's Data Classes to represent energy assets as Python objects. The table below gives a summary of the available modules and data classes.

The aim of EnergyDataModel is to provide the energy data and modelling community with a Python-based open-source tool to enable improvement of software engineering aspects like code quality, maintainability, modularity, reusability and interoperability. We believe that bringing more rigorous software engineering practices to the energy data community has the potential to radically improve productivity, collaboration and usefulness of software tools, utimately leading to better energy decisions.

Our philosophy is aligned on usefulness and practicality over maximizing execution performance or some kind of esoteric theoretical rigor. A well-know quote by Abelson & Sussman comes to mind:

"Programs [software] are meant to be read by humans and only incidentally for computers to execute"

Making code explicit, readable and intuitive counts.

Create an energy system made up of two sites with co-located solar, wind and batteries and save as a .json-file.

import energydatamodel as edm

pvsystem_1 = edm.PVSystem(capacity=2400, surface_azimuth=180, surface_tilt=25)
windturbine_1 = edm.WindTurbine(capacity=3200, hub_height=120, rotor_diameter=100)
battery_1 = edm.Battery(storage_capacity=1000, min_soc=150, max_charge=500, max_discharge=500)

site_1 = edm.Site(assets=[pvsystem_1, windturbine_1, battery_1],
                  latitude=46, 
                  longitude=64)

pvsystem_2 = edm.PVSystem(capacity=2400, surface_azimuth=180, surface_tilt=25)
windturbine_2 = edm.WindTurbine(capacity=3200, hub_height=120, rotor_diameter=100)
battery_2 = edm.Battery(storage_capacity=1000, min_soc=150, max_charge=500, max_discharge=500)

site_2 = edm.Site(assets=[pvsystem_2, windturbine_2, battery_2],
                  latitude=51, 
                  longitude=58)

portfolio = edm.Portfolio(sites=[site_1, site_2])

portfolio.to_json()
