Analysis of Off-grid Energy Systems for Small Villages at Three Different Locations

Abstract: The development of new communities to facilitate the growing population isan ongoing trend, with locations outside the city limits so as to have morearea and less pollution. The main need in isolated communities is to secureenergy demand, which is normally done with power supply from the maingrid, which will require new transmission lines and transformer installation,among other things. As we strive for net-zero energy buildings, the energysource should be renewable and clean. So far, the most common andefficient renewable sources available in abundance are solar and windpower. So, based on the location, we investigate how we can make thesystem of combined solar, and wind power a successful energy source sothat the load of the community can be fulfilled while at the same time thepower from the main grid is isolated. This analysis is done for off-gridsystems to analyze a combined Solar and Wind energy production andcalculate the needed storage, also presenting a comparison with Dieselbased generation and an Economical perspective,for the different locations.As an output of this analysis a program has been developed to examineother locations on bases of local load data.
