ABOUT THE COURSE :
This course offers a comprehensive study of electrical distribution systems, emphasizing the fundamental differences from transmission systems in terms of structure and load patterns. With the rapid transition from passive to active networks, driven by the integration of distributed generation, energy storage, and smart-grid technologies, traditional transmission system analysis tools have proven to be insufficient. This
course addresses these emerging challenges by introducing specialized modeling and analysis techniques tailored specifically for distribution systems.

The curriculum encompasses the modeling of essential components, including feeders, distribution transformers, voltage regulators, capacitors, loads and distributed generation. It covers advanced analysis methods, such as load flow and short-circuit analysis, which are crucial for the effective design, planning, and operation of contemporary distribution networks. A particular focus is placed on voltage and reactive power (volt-var) control (VVC), utilizing both traditional and advanced technologies. The course also includes a case study on a practical distribution system, such as the distribution network at IIT Roorkee, providing real-world insights into the operation of distribution systems.

INTENDED AUDIENCE: 
UG and PG Students, Research Scholars, Distribution Utility Engineers, College Teachers, and Industry Professionals.

PREREQUISITES: Power System Analysis.

INDUSTRY SUPPORT: 1. Power distribution utilities.  2. Load dispatch centers.  3. Distribution system equipment manufacturers.
