Modeling of Hybrid Energy Systems Based on Renewable Energy Sources to Cover the Electricity Needs of a Higher Education Institution Using Homer Pro Software

The paper presents the optimization of HRES for covering the electricity needs of a higher education institution using Homer Pro software. 6 scenarios with different system costs were modeled (such as sale and purchase prices of electricity as well as the prices of certain technologies) where technologies such as PV panels, small wind turbines, diesel generators, batteries, etc. were taken into account. The optimization results in all scenarios show that the use of batteries is not profitable and that the need for an additional source of energy such as a diesel generator does not exist. The energy and environmental characteristics of the system were analyzed and it was shown that it is possible to achieve the prosumer type for buildings of similar purpose.
