Agent-based modeling

Definition

Agent-based modeling is a computational method that simulates the interactions of autonomous agents to assess their effects on the system as a whole. This approach allows researchers to explore complex behaviors and outcomes in systems where individual entities, or agents, interact with one another based on defined rules. It is particularly useful in understanding uncertainty and stochastic behavior in power systems, where the actions and decisions of various entities can lead to unpredictable results.
