20101209 system integration project 2, progress meeting presentation
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.TRANSCRIPT

Results
Off grid campground• Autonomous grid• Stand alone grid
Differences with a grid connected systems • Operational capacity is matched to the demand,• The energy need of the local region has the priority,• The operation of the supply system is mainly seasonal, therefore based on
seasonal renewable energy technologies,• The demand and supply should be in equilibrium. One way to do this by energy
storage.
