Digital control and communication are playing an ever more important role in the field of power electronics and power system. C-HIL (Controller Hardware In the Loop) technology can strongly support this technological evolution when applied in the learning process at undergraduate and graduate level.
Moreover it makes power engineering more hands on and interactive as well as accessible to undergraduate students because there are no dangers, costs and tight supervision requirements of the power laboratory.
For example, a well-designed C-HIL system can directly interface with a number of Smart Grid control systems at all levels, and at the same time the control functionality at all time scales and levels of interest can be easily programmed inside the C-HIL system.
Additionally, a well-designed C-HIL system can "speak" the Smart Grid languages of Modbus, IEC61850, CAN, as well as their dialects. With the real time models built into the core of a well-designed C-HIL system generators power systems components become blocks students can play with and develop solid engineering intuition, often years of engineering intuition can be gathered in a matter of weeks.
Let us now look into how the advantages of C-HIL technology convert into digital enhanced learning experience in the field of Smart Grid education.
Feature #1: C-HIL turns the classroom into a Smart Grid laboratory

Moreover, within the exact same environment they can develop power electronics controllers and validate their performance against grid codes.
Feature #2: C-HIL supports multidisciplinary learning and team work
Complexity requires powerful multidisciplinary teams. To be productive and efficient, multidisciplinary teams, in turn, need a collaborative environment where the specific know-hows can work in harmony and lead to higher quality learning experience as well as a more fun one.
In the fields of power electronics and smart grid, a well-designed C-HIL system is exactly such a tool.
Feature #3: C-HIL is compatible with a flipped classroom model
C-HIL technology supports active learning by allowing a flipped classroom pedagogical model to be used, in which lecture and homework elements of instruction are reversed.
Students are encouraged to do their own learning and experimentation in the C-HIL virtual environment and the in-class time is devoted to teamwork and discussions.
A well designed C-HIL system is a universal real-time machine with a rich set of I/O functionality and an integrated design, modeling, testing and data acquisition software that turns it into a comprehensive Smart Grid educational tool.
