ECTS:  3    


A recent trend is to augment wind power with solar PV production and various batteries based energy storage systems in so-called hybrid power plants. In this way, a better utilization of plant infrastructure, a steady power output over longer time periods and thus a better integration in energy markets are achieved. Moreover, such a plant can deliver firm ancillary services which may not be provided by the individual components alone. This three days course gives a systematic approach for modelling, control design and operation of Hybrid Power Plants using the Model-Based Design approach. It includes a wide range of hands-on exercises as well as demonstrations in a Real-Time Hardware-In-the Loop framework. The main focus in this course will be on:  

  • Plant architectures and interoperability  
  • Balance of plant configuration, topologies and sizing  
  • Information and communication technologies   
  • Model based approach for control design  
  • Grid Monitoring and Ancillary services  
  • Market participation  

Lectures are alternated with practical exercises on each major topic. More than 40% of the course is used for practical exercises and laboratory demonstrations.  

Day 1:

  • Hybrid Power Plants – an overview – Florin Iov (2.5 hours)

    • Market integration and grid support services  
    • Practical considerations on Balance of Plant   
    • Methodologies and tools for design and assessment (offline simulations  and RT-HIL)  
  • Information and Communication Technologies – Rasmus Olsen (3.5 hours)  
    • Communication networks architectures and technologies  
    • Protocols and standards  
    • Performance definitions and classification  
    • Models for ICT (offline simulations  and RT-HIL)  
    • Practical exercises  

Day 2:   

  • Modelling of Assets and Grid – Catalin Iosif Ciontea (2 hours)  

    • Modelling requirements for specific studies  
    • Performance models vs detailed models (wind turbines, PV, energy storage, etc.)  
    • Grid models (voltage control studies, frequency control studies)  
    • Practical exercises  
  • Grid Monitoring – Karthikeyan Nainar and Florin Iov (2 hours)

    • Practical exercises  

Day 3:   

  • Ancillary Services – Florin Iov and Karthikeyan Nainar (2 hours)  

    • Frequency and voltage regulation  
    • Other advanced functionalities (e.g. PSS like, power smoothening, power firming) • Practical exercises  
  • Market Participation – Karthikeyan Nainar (2 hours)  

    • Overview of energy and ancillary service markets  
    • Optimization framework for economic dispatch  
    • Practical exercises  
  • RT-HIL demonstrations – Catalin Iosif Ciontea (2 hours)  
    • Architectures and practical considerations for RT-HIL deployment  
    • Demonstrations of operation and control of a hybrid power plant in a RT-HIL framework  


Basic knowledge on Matlab/Simulink including Toolboxes is recommended for the exercises.
