摘要:

随着分布式新能源和电动汽车等虚拟储能的广泛接入,电力系统的不确定性和低惯量特性变得更加显著,系统的频率运行风险增加,并且主动配电网内部的供需关系呈现出更加灵活多样的特征,导致其与输电网之间的功率交互关系也更加复杂。为此,构建了一种基于主动配电网灵活性支撑机制的电-碳-绿证分布式协同优化方法,以充分挖掘输配系统中分布式资源的支撑能力及其碳减排效益。首先,建立了与输配协同系统匹配的动态频率安全约束和基于双向调节模型的主动配电网灵活性支撑机制,提出了输配系统间的电-碳-绿证协同交互框架。为应对新能源出力的不确定性,将两侧子系统中涉及不确定变量的约束建模为联合机会约束。采用交替方向乘子法(alternating direction of multipliers algorithm,ADMM)进行输配系统的分布式协同。仿真结果表明,所提模型能够有效挖掘配电网中分布式资源的支撑潜力,灵活体现主动配电网的向外支撑能力或被支撑需求。与传统方法相比,系统动态频率安全性和输配协同调节灵活性显著提升,总运行成本较输电网单独调度模型降低13.42%,新能源减载量较忽略多市场耦合模型减少16.76%,系统运行经济性和低碳性明显改善。此外,所提出的求解方法比基于传统的样本平均近似方法减少约98%的计算时间,能够实现输配系统的快速分布式协同优化。

Abstract:

The widespread integration of distributed renewable energy sources and virtual energy storage, such as electric vehicles, exacerbates the inherent uncertainty and low-inertia characteristics of power systems, thereby heightening frequency violation risks. Concurrently, the increasing flexibility and diversity of supply-demand dynamics within active distribution networks (ADNs) further complicate their interactions with transmission grids. To address these challenges, this paper proposes a novel power-carbon-green certificate distributed cooperative optimization framework based on the flexibility support mechanism of ADNs, with the objective of maximizing the utilization of distributed regulation resources and enhancing carbon reduction potential within integrated transmission-distribution (ITD) systems. Firstly, the dynamic frequency security constraints tailored to ITD systems and a flexibility support mechanism for ADNs based on interactive regulation modeling are established, forming a comprehensive ITD electricity-carbon-green certificate cooperation framework. To effectively address the uncertainty inherent in subsystems, joint chance constraints (JCCs) are employed to model the probabilistic nature of the problem. The Alternating direction of multipliers algorithm (ADMM) algorithm is adopted for the distributed cooperation of the transmission and distribution system. Case studies demonstrate the effectiveness of the proposed method in fully leveraging distributed resources and enhancing system frequency security. The framework also exhibits the ability to flexibly reflect the external support capacity or supported demand of ADNs. Compared to the transmission-grid independent dispatch model, the total operation cost is reduced by 13.42%, while renewable energy curtailment is decreased by 16.76% relative to the model that ignores multi-market coupling. These results demonstrate significant improvements in both the operational economy and low-carbon performance of the system. Furthermore, the proposed method achieves a reduction of approximately 98% in computational time compared to the traditional sample-average approximation (SAA)-based approach, thereby facilitating rapid distributed coordination within ITD systems.
