Feasible Solutions

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.

Abstract In this paper, we present a global and multi-timescale approach for assessing energy tran- sition policies aiming at fully renewable generation in power systems of non-interconnected areas, typically islands or isolated regions. The approach links together three dynamic mod- els:(i) a capacity expansion model, ETEM-SG, proposes an investment and production plan for typical days, at the horizon 2030; (ii) a simplified dispatch model is used to validate the production plan for a full year data of weather and demand variations and; (iii) a static & dynamic power system analysis is used to assess the stability of the new power network for fast occurring events like, e.g., a sudden reduction of renewable production. The proposed three-stage approach generates a least-cost long-term investment planning that ensures a supply-demand balance at an hourly time-step and power network statibility at a few mil- lisecond time scale. The presentaion is based on a case study fully described in a report [1] made with ADEME, the French Agency for ecological transition, for the French island La R ́eunion. It shows how a reliable 100% renewable power supply is reachable by 2030, in this area.

The Cost

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.
