Electricity demand predicting is essential for grid operations by making sure that stability between electricity supply and demand. We utilize machine learning (ML) for this work which leads to more accurate and adjusted predictions frameworks compared to existing time series models.

A lot of machine learning projects are going on now a day we also update ourselves to change in trend. More over our research squad will provide enhancements and adjustments can be done if you are locked in any phases of research. More than 120+ countries we are providing support so stay connected with us to know more.

The following is a process guide to deploy ML for electricity demand forecasting:

  1. Data Collection:
  • We gather previous electricity demand data more often basically in hourly intervals.
  • Identical external variables like weather data (temperature, humidity), calendar variables (holidays, day of the week), and other relevant activities can assist us.
  1. Data Pre-processing:
  • We manage missing values by imputation and elimination techniques.
  • Normalization and standardization the data when we need.
  • Feature engineering: Retrieving features such as hour of the day, month, weekday/weekend, etc. Lagged values (for instance: demand from past hours) also support us in our work.
  1. Time Series Split:
  • We utilize a time-based segment for instructing and test sets. For example, when we get data from 2010 to 2020, we train on 2010-2018 and test on 2019-2020.
  • For model validation we consider using a rolling forecast origin and time series in cross-validation.
  1. Selecting Model: There are several famous frameworks can be used for forecasting which we includes:
  • Linear regression models with time features and exogenous variables.
  • Random forests and gradient boosting machines
  • For series like time sequence data we employ Recurrent Neural Networks (RNN) and Long Short-Term Memory (LSTM) networks which give effectiveness.
  • To perform well for datasets with strong seasonal formats we use Prophet by Facebook.
  1. Model training:
  • We instruct our framework on the training dataset.
  • For improving the hyperparameters we implement cross0validation on the training set.
  1. Evaluating Model:
  • Validating the framework’s effectiveness on the test set. We utilize some general metrics for time series forecasting including Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE).
  • To make sure there is no design left which would show our model is losing some structure in the data we examine the residuals’ plots.
  1. Deployment of Model: Once we get fulfilled with our model’s efficiency we apply it for real-time and batch predictions. We make sure that our techniques used to retrain the framework regularly with latest data.
  2. Review Loop: We constantly track the model’s forecasting and differentiate them with the real demand. This supports us in finding when the model begins to drift and requires retraining.
  3. Retraining: When the model’s efficiency gets worse we retrain it. This process includes extending new features, updating hyperparameters, and sometime selecting the latest framework.

Tips:

  • Implementing domain skills assist us to enhance our framework. For instance, we knowing peak demand times, interpreting the significant of particular activities and analyzing the relationship between temperature and demand are useful in our project.
  • We group techniques where multiple frameworks detections are integrated and lead to more powerful and accurate predictions.
  • The deep learning structures like LSTMs can be very robust that they need more data and difficult to instruct and understand than earlier ML models.

     Finally, our choice of model and features hugely based on the state of data, the predicting horizon (short-term vs. long-term), and the particular needs of the electricity grid operation in our problem. So if you want more support contact our team and make you research work simply extraordinary by giving professional touch.
