Abstract

Under the guidance of the 'dual carbon' goals and 'rural revitalization' strategy, the development of microgrids primarily based on wind, solar, and biogas energy is rapidly advancing in rural areas. A critical and challenging area of current research is how to optimally configure the capacity of these microgrids of varying sizes, taking into account the availability of resources in the system's environment and specific climatic conditions, to maximize economic benefits. Based on this, the article constructs a model of a hybrid AC/DC microgrid system powered by wind, solar, and biogas energy. It undertakes multi-objective optimization to achieve the highest utilization of renewable energy, the most economical cost, and the minimum carbon emissions while ensuring the reliability of the system's power supply. The study explores the economically and technically optimal configuration of this microgrid energy system under certain climatic conditions. The results indicate that the optimal configuration for a rural microgrid powered by wind, solar, and biogas energy should include a 2.6 kW biogas generator, 30.00 kW solar panels, 5.24 kW wind turbines, a 2.6 kW battery storage system, and a 10.00 kW bidirectional inverter. This configuration results in the lowest total net cost of the system, achieving optimal outcomes in terms of total net cost, cost per kilowatt-hour, and supply reliability.

风能、太阳能、沼气和交直流转换储能混合型农村微电网的经济和技术优化研究

在 "双碳 "目标和 "乡村振兴 "战略的指导下，以风能、太阳能和沼气为主要能源的微电网发展正在农村地区迅速推进。当前研究的一个关键和具有挑战性的领域是，如何在考虑系统环境资源可用性和特定气候条件的情况下，优化配置这些不同规模微电网的容量，从而实现经济效益最大化。在此基础上，文章构建了一个以风能、太阳能和沼气为动力的交直流混合微电网系统模型。该模型进行了多目标优化，以实现最高的可再生能源利用率、最经济的成本和最低的碳排放量，同时确保系统供电的可靠性。研究探讨了在特定气候条件下，该微电网能源系统在经济和技术上的最优配置。结果表明，以风能、太阳能和沼气为能源的农村微电网的最佳配置应包括 2.6 千瓦沼气发电机、30.00 千瓦太阳能电池板、5.24 千瓦风力涡轮机、2.6 千瓦蓄电池储能系统和 10.00 千瓦双向逆变器。这种配置使系统的总净成本最低，在总净成本、每千瓦时成本和供电可靠性方面达到最佳效果。

期刊介绍： With ICT pervading everyday objects and infrastructures, the ‘Future Internet’ is envisioned to undergo a radical transformation from how we know it today (a mere communication highway) into a vast hybrid network seamlessly integrating knowledge, people and machines into techno-social ecosystems whose behaviour transcends the boundaries of today’s engineering science. As the internet of things continues to grow, billions and trillions of data bytes need to be moved, stored and shared. The energy thus consumed and the climate impact of data centers are increasing dramatically, thereby becoming significant contributors to global warming and climate change. As reported recently, the combined electricity consumption of the world’s data centers has already exceeded that of some of the world''s top ten economies. In the ensuing process of integrating traditional and renewable energy, monitoring and managing various energy sources, and processing and transferring technological information through various channels, IT will undoubtedly play an ever-increasing and central role. Several technologies are currently racing to production to meet this challenge, from ‘smart dust’ to hybrid networks capable of controlling the emergence of dependable and reliable green and energy-efficient ecosystems – which we generically term the ‘energy web’ – calling for major paradigm shifts highly disruptive of the ways the energy sector functions today. The EAI Transactions on Energy Web are positioned at the forefront of these efforts and provide a forum for the most forward-looking, state-of-the-art research bringing together the cross section of IT and Energy communities. The journal will publish original works reporting on prominent advances that challenge traditional thinking.
