A Microgrid can be defined as a part of the grid with elements of prime energy movers, power electronics converters, distributed energy storage systems and local loads, that can operate autonomously but also interacting with main grid. The functionalities expected for these small grids are: black start operation, frequency and voltage stability, active and reactive power flow control, active power filter capabilities, and storage energy management. This way, the energy can be generated and stored near the consumption points, increasing the reliability and reducing the losses produced by the large power lines. In addition, as one of current trends and developments the Internet of Things (IoT) is affecting and will shape the society and the world in all respects. The meet of IoT and energy industry naturally brings the promise of Energy Internet round the corner to introduce significant advantages and opportunities: enhanced automation, controllability, interoperability and energy efficiency, smarter energy management, and so on. The course starts giving some examples of Microgrids in the world. The course participants not only will learn modeling, simulation and control of three-phase voltage source inverters operating in grid-connected mode and islanded mode, but also, how these power electronics converters are integrated in AC Microgrids and how to be extended Energy Internet at a systemic level.
Relevant concepts like frequency and voltage droop control as well as the virtual impedance concept are explained in detail. Finally, this course also introduces the study of the hierarchical control of Microgrids for AC electrical distribution systems, stability analysis based on small signal models, as well as Energy Internet-enabled opportunities and advanced solutions.

  • Day 1: Microgrids Systems Overview, Modelling and Control.
    Lecturer: Ernane Coelho (3h), Josep Guerrero (1h), Juan Vasquez (1h) and Yajuan Guan (1h)

  • Day 2: Distributed Energy Storage Systems, Hierarchical Control, and IoT-enabled energy internet solutions
    Lecturer: Josep Guerrero (2h), Juan Vasquez (2h), Yajuan Guan (2h)


Knowledge on power electronics modelling, control theory and Matlab/Simulink is recommended for the exercises.

Form of evaluation:

The participants will be grouped and asked to team work on several case study scenarios and tasks proposed along the course. The course assessment will be done through a final multi-choice test in combination with delivery of exercises reports.


6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry.
