TMH PV Simulator Challenge

This application generates simulated power values in two parts and uses RabbitMQ to connect them.

• meter.py generates random values simulating a power consumption of a household during 24 hours then sends them to a RabbitMQ queue
• simulator.py generates values based on a photovoltaic power curve and combines them with the household values received from the RabbitMQ queue

For a more detailed specification see the original task description.

The following instructions for setup and execution are tailored towards systems with apt and bash

Dependencies

RabbitMQ

https://rabbitmq.com/install-debian.html#apt-bintray-quick-start

Python 3 and pip

sudo apt update
sudo apt install python3-pip -y
pip3 install pika tqdm scipy

The software has currently been tested in the following configuration

• Ubuntu Focal
• Python 3.8
• RabbitMQ 3.8.14

Execution

python3 meter.py && python3 pvsimulator.py

The meter process can be followed on the progress bar, then the PV Simulator writes every item to the file output and also the items of each full hour to the console.

PV Simulator will continue to listen for messages until Crtl + C is pressed.

Unit Tests

python3 -m unittest tests/*.py -v

File output

The file is named output.csv. The last two columns are :

• Sum: The sum of the household consumption and the PV simulator values as per requested in the original task description
• Diff: The difference of the household consumption and the PV simulator values shows how much power the household needs to draw from the main power line (if positive) or how much reserve energy is generated from the photovoltaic module (if negative)
