Power Hardware in the loop is a next step in simulation world... there are a lot of innovation happening in the field of sensors, measurements, ICT and other smart grid related fields. But just simulink simulation alone does not help us ... also we cannot just go to utility and ask them to connect our new technology into existing power system. So solution is Power Hardware in the loop technique. I would like to discuss about this technology in this knowledge community. Those who are wants to learn and share their knowledge please comment ...
