description
Progress presentation of the initial study for my graduation (named System Integration Project II). Graduation theme is “Electrical and thermal energy balance analysis for an off-grid campground site”. The graduation research is performed at the Eindhoven University of Technology in the research group of prof.dr.ir Jan Hensen. Each month all the graduate students have to present their progress of the last month.

Energy Storage
• Each type of energy storage has its own • specific function• temperature range• capacity
• Dependent on the demand profile (time)• Dependent on the supply profile (time)

Research Question SIP II
“Which renewable energy technologies are the most suitable to supply the electrical and thermal energy balance of an off-grid campground, and in which way will these
renewable energy technologies be integrated in the off-grid energy supply system?”
• Not a clear answer, depend on the demand / supply profiles• Each renewable energy technology has parameters which are not yet set (time, location,
technology)• To prevent a high use of energy storage, different renewable energy technologies will be used• System integration strategy; Always use the supply systems (renewable energy technologies, when
these are not sufficient generation technologies will be used (heat pump, CHP), for problematic situations an diesel power generator can be used as backup. The overall goal is to supply the energy demand of the campground with 100% renewable energy.
