摘要:

目的 在能源资源紧缺与环保需求加剧的背景下,分布式供能技术尤其是可再生能源技术因能效高、经济性好、安装灵活而备受关注。对于公共供电网无法覆盖的高原、边防、孤岛等偏远地区,孤岛微电网已然成为解决用电难的关键技术。然而,如何深入优化能量管理效能,仍是当前面临的一大挑战。为此,围绕孤岛微电网中电能的经济性和稳定性两大核心目标展开综述。 方法 首先分析了国内外孤岛微电网的发展现状及研究重点。然后探讨了孤岛微电网的基本功能和管理对象;此外,还介绍了微电网能量管理的技术路线和3种控制策略;最后,结合现有技术缺陷和新型技术的发展对孤岛微电网能量管理系统的研究方向进行了展望。 结论 研究结果能够有效应对可再生能源的波动性和不确定性,保证系统的稳定运行;可以有效降低储能成本,提高能源利用效率,从而实现更高的经济效益;也可为未来孤岛微电网与新型技术的深度融合提供参考和启示。

Abstract:

Objectives Against the backdrop of energy resource scarcity and increasing environmental demands, distributed energy supply technologies, particularly renewable energy technologies, have attracted significant attention due to their high energy efficiency, cost-effectiveness and flexible installation. For remote areas such as plateaus, border regions and islands, which are beyond the coverage of public power grids, islanded microgrids have become the key technology to address electricity access challenges. However, optimizing energy management efficiency remains a major challenge. This paper reviews the two core objectives—economic efficiency and stability—of electric energy in islanded microgrids. Methods The current development status and research priorities of islanded microgrids, both domestically and internationally, are analyzed. The basic functions and management objectives of islanded microgrids are discussed. Additionally, the technical approaches for microgrid energy management and three types of control strategies are introduced. Finally, the paper provides a discussion of future research directions for islanded microgrid energy management systems, based on existing technological limitations and the ongoing development of new technologies. Conclusions The research results can effectively deal with the volatility and uncertainty of renewable energy and ensure the stable operation of the system. It can effectively reduce the cost of energy storage, improve the efficiency of energy utilization, and achieve higher economic benefits. It can also provide references and insights for the future integration of islanded microgrids with new technologies.
