The main task was to plan the energy supply for settlements using the MicroGrid system method based only on renewable energy sources. Four types of locations were analyzed, where the availability of different renewable energy resources vary. These locations are: desert, island, highland, plain. To find the ideal places, the geographic and climatic circumstances for many regions worldwide were reviewed. After finding the places, the next objective was to determine the load curve for settlements with 10 000 inhabitants. In the next step, the energy production side was defined. The generation of power for the weather-dependent (solar, wind) and -independent (water, biogas) renewable sources was analyzed. In favour of the energy balance, the required storage capacities were analyzed. Most importantly, the electricity supply should be secured under any weather conditions. The aim of the work was the comparison and analysis of different power supply portfolios. The results show the difficulties of the energy supply using the MicroGrid based on only renewable energy sources.
