【摘要】：能源资源与负荷中心逆向分布特征,决定了为提升能源综合使用效率、实现跨大区资源优化配置,需大力发展特高压直流输电技术。在目标电网发展和演变进程中,交直流混联电网将会呈现出混联结构差异化、电源类型多元化、直流落点规模化、交直耦合效应和动态行为复杂化等特征,不同混联格局则具有其鲜明的稳定特性。应用直流多速率、大容量、多类型功率调控功能,是混联电网稳定控制的重要技术手段,也是实现智能化和柔性化控制的重要措施。以我国运行与规划电网为背景,梳理8类直流参与电网稳定控制的典型场景及策略,并提出促进工程应用的技术发展需求。研究结论,对深入理解交直流混联电网稳定特性,提升混联电网安全稳定运行控制能力,提供了重要技术支撑。
[Abstract]:The reverse distribution of energy resources and load centers determines the optimal allocation of resources across large regions in order to improve the efficiency of comprehensive use of energy. It is necessary to develop UHVDC transmission technology vigorously. In the development and evolution process of the target power grid, the AC / DC hybrid grid will show mixed structure differentiation, power supply type diversification, DC impact point scale. The cross-direct coupling effect and dynamic behavior are complicated, and the different mixing patterns have their distinct stability characteristics. The DC multi-rate, large-capacity, multi-type power regulation function is applied. It is an important technical means of stability control of hybrid power network, and also an important measure to realize intelligent and flexible control. The typical scenarios and strategies of 8 types of DC involved in power grid stability control are sorted out, and the technical development requirements to promote the engineering application are put forward. The conclusion of the research is to deeply understand the stability characteristics of AC / DC hybrid power system. It provides important technical support to improve the safety and stability operation control ability of hybrid power grid.
