Special Issue Information

Dear Colleagues

Distributed Energy Resources (DERs) represent a transformative force in the modern energy landscape, reshaping the way electricity is generated, managed, and consumed. As the global energy sector transitions towards more sustainable and resilient systems, DERs—including solar photovoltaic systems, wind turbines, energy storage solutions, electric vehicles, and demand response technologies—are at the forefront of this evolution.

This Special Issue aims to bring together cutting-edge research and innovative solutions that address the technical, economic, and regulatory challenges associated with DERs. We invite contributions that explore the integration of DERs into the grid, their role in enhancing energy security and reliability, and their potential to support the transition to a low-carbon economy.

Topics of interest include, but are not limited to, smart grid technologies, DER aggregation and optimization, the impact of DERs on grid stability, and the policy frameworks necessary to foster their adoption. This Special Issue seeks to provide a comprehensive overview of the current state of DER technologies, their deployment strategies, and their implications for the future of energy systems. By fostering interdisciplinary collaboration and knowledge exchange, we hope to advance the understanding of DERs and their pivotal role in achieving global energy sustainability goals.

This study presents a comparative analysis of the accuracy of different methodologies for the design and performance evaluation of thermoelectric generators (TEGs), using analytical, computational numerical, and experimental approaches. TEGs are promising devices for capturing waste energy in industrial processes, converting waste heat into electrical energy and contributing to energy sustainability. However, the efficiency of TEGs is a significant challenge due to their low conversion rates. To address this challenge, three different methodologies were developed and systematically compared. Analytical Model: Developed for the electrical design of thermoelectric micro generators, using theoretical performance data and industrial temperature gradients. This method offers a robust theoretical view but may not capture all practical variables. Computational model in Simulink/MATLAB: Created and validated to consider the variation of the Seebeck coefficient and the internal resistance of thermoelectric modules with temperature. This model provides an accurate simulation of operating conditions but depends on the accuracy of the input parameters. Experimental Multi-string Electrical Arrangement Prototype: This involved the design and construction of a prototype followed by experimental tests to validate its performance. This method provides valuable empirical data but can be limited by the complexity and cost of the experiments. The results show that each methodology has specific advantages and limitations, offering valuable insights for the development of more efficient TEG systems. The comparison of analytical, numerical, and experimental methods revealed differences in accuracy and efficiency, highlighting the importance of an integrated approach to TEG design. This study lays a solid foundation for future research and practical applications in the field of industrial residual energy harvesting. Full article
