Description: 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 advanced control strategies 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, virtual impedance, UPS, virtual synchronize generator 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, communication technologies in AC microgrids, and Energy Internet-enabled opportunities and advanced solutions.

  • Day 1: Microgrids Systems Overview, Modelling, Grid forming and Grid Feeding Control, Hierarchical Control
  • Day 2: Stability Analysis, Passivity-based modelling, Power Flow Analysis and lab. Demonstration
  • Day 3: Virtual Synchorous generators, Industrial Microgrid applications, communications and IoT in Microgrids


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

Price:  6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry excl. VAT.
 A Online link for externals participants will be annonced after deadline for registration

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3.000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
