Load Flow Analysis is a key planning tool used by power system engineers to understand how electricity moves through power networks, like the electrical grid. Think of it as a traffic map for electricity that shows how power flows from power plants to homes and businesses. Engineers use this analysis to make sure the power system is working safely and efficiently, predict potential problems before they happen, and plan for future electricity needs. You might also see this called "Power Flow Analysis" or "Power Flow Study" in resumes and job descriptions.
