portable-app-framework A framework for Energy Management solutions

portable-app-framework is a Python package that provides a toolkit for developing, scaling and maintaining energy management and information systems (EMIS) applications using an ontology-based approach. Key contributions include an interoperable layer based on Brick schema, the formalization of application constraints pertaining metadata and data requirements, and a field demonstration. The framework allows for querying metadata models, fetching data, preprocessing, and analyzing data, thereby offering a modular and flexible workflow for application development.

Main Features

Here are just a few of the things that portable-app-framework does.

Command Line Interface (CLI)

You can use the CLI to to create, manage and update applications

```

portable-app-framework -h

usage: portable-app-framework [-h] {new,update} ...

Utils CLI for the afdd framework.

positional arguments: {new,update} new Create a new application folder from template. update Update README of an application.

options: -h, --help show this help message and exit

```

Application class

A python class that helps to create a portable application. Once you created a new application in your project you can set up and run an application with the following lines of code

```python import pandas as pd import brickschema from portableappframework import Application

app = Application( metadata=brickschema.Graph(), appname='appname' ) qualifyresult = app.qualify() # True/False fetchresult = app.fetch() # Dict of mapped variables df = pd.DataFrame() # get df according to your logic dfpreprocess = app.preprocess(df) finalresult = app.analyze(df_preprocess) ```

Installation

Work on portable-app-framework started in 2021 as an internal project at BAEDA Lab to deploy energy management and information systems application in a most reliable way instead of solving implementation issues from scratch every time. We found that the framework enabled faster deployment of such solutions thanks to the builtin methods that allowed the analyst to skip ripetitive data integration tasks. Moreover allowed non analyst expert of metadata schema to exploit the power of such tools. So we decided to create this package to share our experience with the scientific community and not only.

Its effectiveness is demonstrated through a case study involving the development and implementation of a data-driven anomaly detection tool for the photovoltaic systems installed at the Politecnico di Torino, Italy. During eight months of testing, the framework was used to tackle practical challenges including: (i) developing a machine learning-based anomaly detection pipeline, (ii) replacing data-driven models during operation, (iii) optimizing model deployment and retraining, (iv) handling critical changes in variable naming conventions and sensor availability (v) extending the pipeline from one system to additional ones.} }
