LOAD FLOW EQUATION & THEIR SOLUTIONS | POWER SYSTEM II | LECTURE 04 BY MR. GAURAV SRIVASTAVA | AKG

**Course Introduction** Power System Analysis is one of the core courses in Electrical Engineering, and power flow computation serves as a pivotal link connecting foundational and advanced topics. This lecture, presented by Professor Gaurav Srivastava from AKG College of Engineering, focuses on the formulation and solution methods of power flow equations. As the fourth lecture in the "Power Systems II" series, this session begins with the bus admittance matrix and systematically derives the mathematical foundations and iterative procedures of classical numerical methods, including the Newton-Raphson method and Gauss-Seidel method. Through representative examples, the instructor progressively examines linearization techniques and convergence criteria, presenting clear logic and detailed derivations. **Target Audience:** Senior undergraduate students majoring in Electrical Engineering and Automation, graduate school applicants preparing for the electrical engineering direction, and engineers working in power system-related fields will all benefit from this course. **Viewing Recommendations:** It is recommended to preview the basic concepts of power flow equations before watching. Working through derivations with pen and paper will enhance understanding. This lecture is part of a series course; studying in sequential order is advised to build a complete knowledge system.
