Power Station Analytics: Algorithm Suite Delivered

Four distinct services were created on this platform, each responsible for a different calculation area. Three Celery workers operated in each of these services on different priority levels in order to have the calculations carried out efficiently and concurrently. The PostgreSQL database provided persistent storage for the data, while Redis acted as the task broker and caching mechanism. Metrics from each service were collected by Prometheus and monitored using Grafana dashboards. This kept each calculation area independent and easy to reason about.

Calculation algorithms for the specific domain were coded in Python, and a normalization algorithm was extended and refined. Automated tests were developed for all of the calculation logic. Celery worker priorities were set so the most important calculations ran first. In terms of monitoring, Prometheus exporters were integrated, along with Grafana dashboards. Together, these covered the full path from algorithm implementation to tested and observable calculations in production.

All services were containerized by using Docker in order to maintain consistency between all environments. Metrics were gathered for every individual service by using Prometheus, while operational dashboards were created by means of Grafana. The platform was deployed on the client’s own infrastructure, as opposed to being deployed in the public cloud. This setup kept the whole system reproducible and under the client's direct control.

The data integrity was guaranteed by ensuring that the input values were checked for their validity prior to running the calculations to prevent malformed input data from reaching the algorithm. The tests covered the edge cases in the numerical calculation logic to catch the silent errors that would go unnoticed otherwise. In a critical application in a power station, it was just as important to catch these errors as it was the outcome of the algorithm. Together, these checks protected the accuracy of every calculation the platform produced.
