Generates simulated photovoltaic (PV) power production and household consumption values and writes the results (in Kilowatts kW) to the disk.

• Docker
• RabbitMQ
• Pika
• Python 3.8

• To create and run the image use the following command, Make sure that docker is already installed in your system.

docker-compose up --build

• Copy storage file from docker container to the local system. Make sure that your docker containers are up and running.

docker cp simulator:/simulator/output.csv ./

The configuration will create a cluster with 3 containers:

• Meter container
• Simulator container
• RabbitMQ container

The Meter container will continuously generates a random consumption value between 0 to 9.0 KW and publishes meter data to RabbitMQ.

The Simulator container will read message from the RabbitMQ and parses the message. Then calculates the PV values using the PV Simulator.

The simlilation values are looks like this,

+------+-------+
| Hour | BasePV|
+------+-------+
|  4   |  0.1  |
|  5   | 0.15  |
|  6   |  0.2  |
|  7   |  0.3  |
|  8   |  0.5  |
|  9   |  1.0  |
| 10   |  2.0  |
| 11   |  2.5  |
| 12   |  3.0  |
| 13   |  3.5  |
| 14   |  3.5  |
| 15   |  3.2  |
| 16   |  3.0  |
| 17   |  2.5  |
| 18   |  2.0  |
| 19   |  1.0  |
| 20   |  0.2  |
| 21   |  0.1  |
+------+-------+

If hour less than 14:00

    Final PV value = BasePV + (0.01 * Minutes)

If hour greater than 14:00

    Final PV value = BasePV - (0.01 * Minutes)

Examples:

11:30 => 2.5 + (0.01 * 30) => 2.8
18:13 => 2.0 - (0.01 * 13) => 1.87

Sum up value = PV value - meter consumption value

Created sum up value with PV values and meter consumption values. Finally all values (timestamp, PV values, meter consumption value, sum up value) stored into a CSV file.

timestamp, pv_value, meter_consumption_value, sumup_value

RabbitMQ container is where messages flow through RabbitMQ and applications, stored inside a queue. A web browser access to the Dashboard is also provided for RabbitMQ message management and monitoring which can be accessed at http://localhost:15672.
