Literature Review on Modeling of Integrated T&D System using Dynamic Phasor Technique

With the advent of transitioning from conventional to the modern structure of electrical power systems, the systems are prone to numerous electrical dynamics that no longer have the luxury to be neglected. As a result , the existing time domain simulation software, such as Electromagnetic Transient (EMT) and Root Mean Square (RMS) programs, are becoming inefficient for larger and complex systems. Moreover, the need for integrated Transmission and Distribution (iT&D) research is becoming an obvious trend with more distributed energy resources connecting to the system. The previous researches in this area of modeling and simulation use different techniques but more assumptions and oversimplification have resulted in less accuracy. On the other hand, there is the Dynamic Phasor (DP) concept developed for the analysis of dynamics in power electronics components. With more power electronics components infusing into the power systems, this technique can become a powerful method to analyze the behaviors of the system. Therefore, this literature survey paper extends the idea to implement the DP technique in modeling iT&D systems owing to its multiple advantages over the other methods.
