A Prediction Method of Solar Power Generator using Machine Learning Techniques
We first purchased a solar power generator, installed it in the right place, and then collected power generation data for the next 12 months. First, we collected weather and power generation data to excel file. For the weather data, the data provided by meteorological agency was secured to ensure the reliability of the information. The collected data can be monitored anytime and anywhere using PC or mobile device. The user interface of these services is planned to be upgraded to be more usable after the accuracy of the service provided. The core development contents are collected data based power generation prediction technique. This is because system failure monitoring can be performed only when a power generation prediction system is configured. Our power generation prediction algorithm was developed based on machine learning. LSTM was used among linear regression and artificial neural network in machine learning. Experiments using the machine learning showed that the accuracy could be increased to 85% when compared with actual power generation.
