Energy Forecasting: A Review and Outlook

Energy forecasting is the process of predicting the future demand and supply of energy sources, such as electricity, natural gas, oil, and renewable energy. Energy forecasting is essential for planning, operating, and optimizing the energy system, as well as for informing policy decisions and market strategies.

In this blog post, we will review the main methods and applications of energy forecasting, as well as the current challenges and opportunities in this field. We will also provide some outlooks on the future trends and directions of energy forecasting research and practice.

Methods of Energy Forecasting

Energy forecasting can be classified into different categories based on the time horizon, the spatial resolution, the type of energy source, and the purpose of the forecast. Depending on these factors, different methods and models can be used to perform energy forecasting.

Some of the most common methods of energy forecasting are:

- Statistical methods: These methods use historical data and mathematical techniques to identify patterns and relationships between energy variables and other factors, such as weather, calendar, economic activity, etc. Statistical methods can be further divided into univariate methods, which only use past values of the energy variable to forecast its future values, and multivariate methods, which use additional explanatory variables to improve the forecast accuracy. Examples of statistical methods are regression models, time series models, exponential smoothing models, etc.

- Machine learning methods: These methods use algorithms that learn from data to find complex and nonlinear patterns and relationships between energy variables and other factors. Machine learning methods can be further divided into supervised learning methods, which use labeled data to train and test the models, and unsupervised learning methods, which do not require labels and can discover hidden structures and anomalies in the data. Examples of machine learning methods are artificial neural networks, support vector machines, decision trees, clustering algorithms, etc.

- Hybrid methods: These methods combine two or more methods from different categories to leverage their strengths and overcome their weaknesses. Hybrid methods can be implemented by using different methods for different time horizons or spatial resolutions, by integrating different methods in parallel or sequentially, or by using meta-learning techniques to select or combine the best models. Examples of hybrid methods are ensemble methods, switching models, hierarchical models, etc.
