考虑静态拓扑及动态调整的新型电力系统弹性评估

Assessment of New Power System Resilience Considering Static Topologies and Dynamic Adjustments

  • 摘要: 为提高新能源消纳率且支撑构建新型电力系统,应合理有效地评估电力系统的弹性,并有针对性地提出改进措施。针对当前电力系统弹性评估较少考虑网架结构影响,未考虑静态弹性与动态弹性之间关联性等问题,提出了考虑静态拓扑以及动态调整的电力系统弹性评估方法。首先,建立了电力系统的弹性分析框架;其次,提出了电力系统静态与动态弹性的评估指标,并分别基于复杂网络理论及动态调整策略评估了电力系统的静态弹性与动态弹性;最后,通过实际网架结构验证了所提理论方法的有效性与适用性。所提的弹性评估可以为新型电力系统建设提供网架结构以及运行方式等方面的参考。

     

    Abstract: In order to increase the consumption rate of new energy and support the construction of new power system, it evaluates the resilience of power system reasonably and effectively and puts forward the improvement measures accordingly.According to the problems that the influence of grid structure and the correlation between static resilience and dynamic resilience are not considered in the current evaluation of power system resilience, a method for evaluating power system resilience considering static topology and dynamic adjustment is proposed.Firstly, it establishes the power system resilience analysis framework.Secondly, it proposes the evaluation indicators of static resilience and dynamic resilience of a power system, and the static resilience and dynamic resilience of power system are evaluated based on complex networks theory and dynamic adjustment strategy respectively.Finally, through actual grid structures it verifies the proposed validity and applicability of the theoretical methods.The resilience evaluation can provide reference for the construction of new power system in grid structure and operation mode.
