Probabilistic modeling

Definition

Probabilistic modeling is a statistical approach that uses probability distributions to represent uncertainties in complex systems. It allows for the incorporation of various sources of uncertainty, providing insights into potential outcomes and their likelihoods, which is particularly useful in forecasting renewable energy generation and demand.
