Learning Outcomes a) Smart Grids
After the successful participation in the course Smart Grids the students are able to:
  • understand the key drivers as well as design principles of the smart grid (communication)
  • evaluate the communication infrastructure required to set up smart grids.
b) Flexible Generation and Demand Side Management
After the successful participation in the course Flexible Generation and Demand Side Management the students are able to:
  • understand the requirements for balancing fluctuating renewable power generation and select solutions for these different requirements
  • estimate potentials and costs in the control of flexible generators and consumers in domestic and industrial applications.
c) Biogas
After the successful participation in the course Biogas the students are able to:
  • determine bio mass potentials taking into account different bio mass conversion processes and local potentials
  • analyse the sustainability of the whole value chain.
Contents a) Smart Grids
  • Overview of smart grids and smart grid communications (SGC)
  • Power generation:
    • equipment-conditioning information and load conditions of the generation equipment
  • Transmission:
    • state of high-voltage power lines
    • devices in the transmission substations
    • power lines and feeders
  • Consumers:
    • overall power-usage information (meter reading) and information about power usage by devices inside the home
    • automatic meter reading
    • advanced metering infrastructure
    • privacy issues in smart grids
  • Communication technologies used in SGC:
    • power line communications
    • fiber optic communications
    • wireless devices
  • Demand Response Management (DR):
    • utility companies and energy load management/reduction
    • factors for DR programs
    • automation of DR as key concept which helps to reduce human intervention and increases accuracy and responsiveness to the DR program
  • SGC:
    • activities in standardization bodies on SGC
    • practical experience gained in SGC lab experiments
b) Flexible Generation and Demand Side Management (DSM)
  • Possibilities and potentials of flexible power generation
  • Differences in temporal power availability
  • Defining requirements
  • Different plant operations to cover residual load under present conditions of power generation
  • Discussing possible flexible balancing solutions
  • DSM potentials:
    • classification
    • describing actual DSM potentials by the state of charge
  • Lab for practical experience with flexible power generation under central European conditions
c) Biogas
  • Different types of biomass and the efficiency of their production:
    • energy plants
    • organic waste
    • agricultural residuals
  • Different ways of using biomass and conversion paths:
    • combustion of solid bio mass
    • thermo chemical gasification
    • anaerobic digestion
    • bio fuels
  • Bio gas as energy source:
    • components and processes of gasification
    • combustion basics with respect to biomass conversion
  • integration of bio energy in conventional and RE systems
