ABSTRACT

  • Photovoltaic (PV) Electricity Generation in power distribution systems is increasing day by day.
  • PV power generation forecasting can result from weather data and Global Horizontal Irradiation (GHI) or simply the Irradiation data.
  • The weather data can be used to predict the power generation of a single day

Primary Idea Behind the Project

  • The GHI Data depends on several parameters such as Air Temperature, relative humidity, wind direction, and wind speed.
  • Using machine learning models to forecast the solar power generation.
  • A small-scale Battery Management System consisting of PV integration, distribution system, and loads is designed to estimate how much of the generated power is required on a particular day.

PREPROCESSING

Standard Scaling from Python Library Scikit-learn (Sklearn) was used to make the data suitable to feed into the models.

The data was split into 80-20 per cent as the training and testing data.
