Content

Photovoltaic Systems

  • Decentralized and stand-alone PV hybrid systems:
    • modular PV systems technology for decentralized AC-power supply
    • large decentralized PV systems (fixed mounted and tracking systems, power condition units and grid integration)
    • PV stand-alone and hybrid systems configurations and components performance
    • supervisory control and energy management strategies for PV decentralized systems
    • storage technology for PV stand-alone systems (super-capacitors, batteries, electrolysis and fuel cells)
    • power conditioning units for decentralized and stand-alone PV-Systems and components (battery charger, bidirectional converters, fuel cell inverters)
  • Economics:
    • specific energy cost calculation
    • techno-economic performance criteria of stand-alone PV and hybrid systems 
  • Design aspects:
    • methodologies for sizing PV hybrid systems
    • design of stand-alone PV hybrid system (load demand synthesis, component sizing, evaluation of performance criteria)
    • implementing simulation tools for designing PV stand-alone systems case study via project work (design of stand-alone PV system)

Energy Efficiency in Buildings

  • Basics of building physics:
    • heat transfer adapted to building elements like walls and windows
    • shading devices, humidity and condensation effects
    •  global radiation on building
  • Conventional vs. unconventional energy use in buildings:
    • thermal comfort, ventilation
    • boilers, cogeneration of heat and electricity, heat pumps
    • passive houses
  • Economic aspects of EE in the building sector:
    • costs and savings of energy efficiency measures
    • life cycle costs and life cycle assessment of environmental impacts
  • Comparing conditions in Germany and the Mena countries
