Abstract

The global urgency to mitigate climate change and reduce greenhouse gas emissions has intensified efforts to transition towards renewable energy sources. Isolated electrical grids, characterized by their detachment from larger networked systems, present unique challenges in this transition. This study, focusing on Israel’s grid as a model for the year 2050, aims to address these challenges by employing a holistic approach that integrates advanced modeling techniques to assess the potential of renewable energy integration effectively.
Employing a comprehensive methodology, this research incorporates a detailed Performance Model (PM) and an Energy Management System (EMS) model. The PM evaluates the hourly electrical output from diverse renewable sources, including solar (photovoltaics and agrivoltaics), onshore and offshore wind, sea waves, and organic waste, taking into account Israel's specific geographic and climatic conditions. The EMS model then optimizes the alignment between this renewable energy supply, the anticipated demand, and necessary storage solutions. This approach includes extensive data collection on renewable energy potentials, area mapping for solar installations, and evaluations of wind and sea wave energy potentials based on geographical and meteorological data. The innovative aspect of considering organic waste adds an additional layer of resource diversification.
The findings reveal a significant potential for Israel to increase its renewable energy share to between 80.1% and 99.5% by the year 2050, contingent upon the implementation scenario. Achieving such a high level of renewable integration hinges on developing substantial energy storage capacities. This research identifies a feasible combination of the Vehicle to Grid (V2G) concept, stationary batteries, and pumped hydroelectric plants as viable solutions for meeting the projected total electric demand of 183.3 TWh in 2050, with renewable resources providing an installed capacity of 180.6 GW.
A key outcome of the study is the emphasis on agrivoltaics and the V2G concept as instrumental in enhancing the grid's renewable capacity. These innovations not only conserve land resources but also offer the requisite storage to manage the inherent variability of renewable energy sources. Moreover, the study underscores the importance of adopting a comprehensive energy management approach capable of accommodating the dynamic nature of renewable energy production and consumption.
This research contributes to the broader discourse on renewable energy potentials in isolated grids, providing critical insights for policymakers, energy planners, and researchers. It underscores the feasibility and necessity of employing advanced modeling techniques to evaluate and optimize the integration of renewable energy sources, highlighting the need for significant storage capacities and innovative solutions like agrivoltaics and V2G.
The implications of this study for energy policy and planning are profound, especially for regions with isolated grids similar to Israel. It encourages policymakers and energy planners to consider the methodologies and findings presented to make informed decisions regarding renewable energy investments and infrastructure development. Furthermore, the research highlights the pivotal role of innovation in energy storage and management technologies in maximizing the potential of renewable energy sources.
In conclusion, the integration of renewable energy into isolated grids, exemplified by the case study of Israel in 2050, is both a viable and essential strategy for moving towards a sustainable energy future. This study lays the groundwork for future research to explore emerging technologies and storage solutions, ensuring that renewable energy can adequately meet growing demands while addressing environmental concerns.
