摘要

交流/直流混合配电网络的引入带动了智能电网和分散式电力系统技术的多项发展。本文集中讨论了与交直流混合配电网运行相关的几个主题。如优化方法、控制策略、能源管理、保护问题和建议的解决方案。神经网络优化方法的实施对于交直流混合微电网(MG)等混合网络中多种能源的成功整合、动态能源管理、系统稳定性和可靠性的建立、配电优化、储能管理以及在线故障检测和诊断具有重要意义。通过神经网络优化技术利用可再生能源发电和降低成本是取得这些进展的关键。除了确定混合系统运行中的挑战外,本文还将该系统与传统的微电网进行了比较,并展示了该类型系统相对于不同微电网结构的优势。这篇综述比较了不同的拓扑结构,特别是交直流耦合混合制导发电机,并说明了用于交直流制导发电机之间高效传输的变流器互连的重要作用,以及通常用于实施不同控制和优化技术的变流器互连的重要作用。总之,这篇综述论文可作为参考文献,指出了交直流混合配电网络集成的利弊,为这一发展中领域的未来研究和改进路径提供了参考。

A comprehensive review of hybrid AC/DC networks: insights into system planning, energy management, control, and protection

The introduction of hybrid alternating current (AC)/direct current (DC) distribution networks led to several developments in smart grid and decentralized power system technology. The paper concentrates on several topics related to the operation of hybrid AC/DC networks. Such as optimization methods, control strategies, energy management, protection issues, and proposed solutions. The implementation of neural network optimization methods has great importance for the successful integration of multiple energy sources, dynamic energy management, establishment of system stability and reliability, power distribution optimization, management of energy storage, and online fault detection and diagnosis in hybrid networks like the hybrid AC–DC microgrids (MG). Taking advantage of renewable energy generation and cost-cutting through the neural network optimization technique holds the key to these progressions. Besides identifying the challenges in the operation of a hybrid system, the paper also compares this system to conventional MGs and shows the benefits of this type of system over different MG structures. This review compares the different topologies, particularly looking at the AC–DC coupled hybrid MGs, and shows the important role of the interlinking of converters that are used for efficient transmission between AC and DC MGs and generally used to implement the different control and optimization techniques. Overall, this review paper can be regarded as a reference, pointing out the pros and cons of integrating hybrid AC/DC distribution networks for future study and improvement paths in this developing area.
