Microgrids are emerging as feasible solutions to handle local energy systems. Several factors influence the development of such systems, such as technical, economic, social, legal, and regulatory issues. These important aspects need to be addressed to design appropriate microscale projects that take into consideration adequate technology without underestimating local characteristics. This article aims to propose a framework design for microgrid optimization using technical, social, and economic analysis. The framework is presented through a small island case study that shows each step of the method. As a contribution, this work provides a multi-objective optimization framework with different criteria consideration, such as the inhabitants’ cost of living and inter-cultural aspects, instead of traditional technical and economic analysis. The results show the applicability of the proposed framework showing better alternatives when compared with actual or future improvements in the study case scenario.

Soybean is considered to be an alternative crop and its cultivation could offer an innovative and high-quality product. A case study was implemented on an existing farm to examine the prospects of soybean production in Greece and to evaluate the economic outcomes of the crop cultivation under organic and conventional cropping system. The economic analysis showed that the cost of conventional soybean production was 0.37 €/kg, while the cost of organic soybeans was 0.50 €/kg. The organic and conventional soybean selling prices were 0.6 and 0.4 €/kg, respectively. In addition, the financial performance of the farm improved after the introduction of organic soybean crop, where the net profit increased by 26.3% compared to the initial profit of the farm, while the increase in the conventional was less at 10%. Soybean is a relatively new crop in Greece with high net profit, especially under organic cultivation mainly due to lower inflow of external imports.
