Electrical Distribution System Analysis

Participants should join this course to gain a clear understanding of modern electrical distribution systems and their unique challenges. It equips learners with practical modeling and analysis skills needed for active, smart distribution networks. The course also bridges theory and practice through real-world case studies.

This course provides a clear and practical understanding of electrical distribution systems and explains how they differ from transmission systems in terms of structure and load behavior. With the growing use of distributed generation, energy storage, and smart-grid technologies, distribution networks are changing from simple, passive systems into active and complex ones. Because of this, conventional analysis methods used for transmission systems are no longer sufficient. This course introduces analysis and modeling techniques specifically developed for modern distribution systems.The course covers the modeling of important distribution components such as feeders, transformers, voltage regulators, capacitors, loads, and distributed generation units. It also explains essential analysis techniques like load flow and short-circuit analysis, which are necessary for the planning, design, and operation of today’s distribution networks. Special attention is given to voltage and reactive power control (volt-var control) using both conventional and advanced approaches. In addition, the course includes a real-world case study of a practical distribution system, such as the distribution network of IIT Roorkee, to help learners connect theory with real-life applications.
