Optimizing power line connections between stations and consumers
Introduction
Electrical grids connect power plants to millions of homes and businesses through a complex network of transmission lines and substations. These networks can be modeled as graphs where power stations are vertices and transmission lines are edges. Engineers face optimization problems: What's the minimum total cable length needed to connect all locations? How can power flow be maximized through the network? What happens when a line fails? Graph theory provides powerful tools to answer these questions, using concepts like minimum spanning trees, network flow algorithms, and connectivity analysis.
