The fundamental course of power system modeling is designed to expose participants to the development of models of major power system components such as synchronous generators, transformers, transmission lines, excitation systems, and speed governors. In addition to this, modeling of converter-based renewable energy sources, loads, and prime movers shall be introduced. An insight into the mathematical modeling of power system components is necessary to comprehend when goes behind when a power system is modeled in any power system modeling and analysis software.
