Advancements and challenges of a multi-platform real time simulation lab for power applications

Real-time simulation and its use in Hardware in the Loop and Power Hardware in the Loop testing may not be realized with one single hardware platform. Instead, multiple systems are needed to realistically address the analysis and testing needs of the smart grid. This is particularly the case when the target system is the future electrical distribution grid, with its multi-physic, hybrid nature, its pervasive power electronics and communication. The approach adopted at the authors´ laboratory is presented to exemplify the interface and integration challenges when such platform is extended to realize relevant scenarios.
