Test systems for dynamic stability studies in electric power system

Electric power system is one of the largest and complex infrastructures made by mankind during the last century. The total investment associated with it in trillions of dollars. As it is a very expensive, large and complex physical system, secure network operation without having any system wide instability issue and catastrophic consequences is sought. As a result power system educators and researchers are constantly scrutinizing power system with changing scenarios and coming up with the new solutions to keep the most important infrastructure intact in order to make the economy and society sustainable. It is tough, but not impossible, and expensive to build physical test power systems to perform various researches. Hence, the test power systems models have been playing a key role for better understanding, development, and deployment of new solutions in power system problems. There have been many test systems with varying complexities and sizes used all around the world. However, there is no common platform where the most of these test systems are documented so that the educators and researchers can chose an appropriate test system suitable for their studies. The paper presents a collection of commonly used test systems for various dynamic stability studies.
