光储直柔技术的特点与应用探讨

Brief Discussion on the Characteristics and Application of Photovoltaics,Energy Storage,Direct Current and Flexibility Technology

随着国内分布式能源和新能源充电桩的快速发展,当前依托于交流配电的电网结构承受着日益显著的压力。为突破交流系统的垄断,直流系统需利用自身优势在合适场景中率先应用。进行了交直流系统在应用中的优劣势对比,描述了直流系统的组成及其相应造价,提出直流技术的多个发展阶段,描述了一种兼容交流的直流配电组织形式,并对未来因直流产业发展而产生的应用场景进行展望。

With the rapid development of domestic distributed energy and new energy charging piles,the current grid structure relying on AC power distribution is under increasing pressure.In order to break through the monopoly of the AC system,the DC system needs to take advantage of its own advantages and be the first to apply it in suitable scenarios.This paper compared the advantages and disadvantages of AC and DC systems in application,described the composition of DC systems and their corresponding costs,put forward several development stages of DC technology,described a form of DC power distribution that was compatible with AC,and looked forward to the application scenarios that may arise from the development of the DC industry in the future.
