This method article proposes the establishment of a feasibility space as an objective to be achieved during the development of new technologies to convert energy from renewable resources. The feasibility space can also be a reference when designing an energy system based on renewable resources. The feasibility space is a set of parameter values for the design stage that define the economic and technical feasibility of an energy system or a new technology, which must be satisfied when the energy system comes into operation or when the new technology for converting power goes into operation. The study of possible feasibility spaces allows characterizing energy systems or new technologies as attractive investments, or on the other hand, as unfeasible ventures. - The method proposes to establish a goal to achieve during the development of technologies for energy conversion - The method provides a benchmark for both the stages of design and development of generation systems and new technologies - The feasibility space constitutes a planning tool for power systems based on renewable resources of any size, Comment: method article, 4 pages, 1 figure, 2 tables, 6 references

Homer Legacy software is a well-known software for simulation of small hybrid systems that can be used for both design and research. This dataset is a set of files generated by Homer Legacy bringing the simulation results of hybrid energy systems over the last seven years, as a consequence of the research work led by Dr. Alexandre Beluco, Federal University of Rio Grande do Sul, in southern Brazil. The data correspond to thirty papers published in the last seven years. Two of them describe hydro PV hybrid systems with photovoltaic panels operating on the water surface of reservoirs. One of these twelve papers suggests the model-ing of hydropower plants with reservoirs and the other the modeling of pumped hydro stor-age, and a third still uses these models in a place that could receive both the two types of hy-droelectric power plant. The other simulated hybrid systems include wind turbines, diesel generators, batteries, among other components. This data article describes the files that inte-grate this dataset and the papers that have been published presenting the hybrid systems under study and discussing the results. The files that make up this dataset are available on Mendeley Data repository at dx.doi.org/10.17632/ybxsttf2by.2., Comment: 7 pages, 1 table, 23 references
