Challenges of modeling electrical distribution networks in real-time

This paper describes the challenges associated with real time modeling of electrical distribution networks. Distribution networks are tightly coupled electrically which makes it more difficult to model them using parallel processing techniques. Power electronic devices and distributed energy resources are continually increasing the complexity of distribution networks and consequently the task of simulating them in real time is more difficult. Detailed and accurate models need to be made available to represent distribution loads as well as protection and control equipment. In addition, a wide variety of communication protocols with significant bandwidth are required. Finally the trend to apply Power Hardware in the Loop simulations to test distribution equipment is a challenge in of itself.
