摘要

在新型电力系统背景下,含多微网的主动配电网在协同运行过程中,存在着多元主体利益分配与多重多级不确定性的问题。为应对上述挑战,提出一种基于动态定价机制的双层分布鲁棒调度策略,以实现主动配电网对多微网能源精细化管理。首先,针对主动配电网与多微网的利益分配公平问题,提出一种考虑支路网损和能源-负荷分布情况的动态定价机制。在此基础上建立双层模型,上层主动配电网为主体,通过动态定价机制制定多微网的交易电价;下层多微网为从体,根据自身负荷需求对电价做出响应。其次,考虑主网电价、新能源出力不确定性的影响,构建双层分布鲁棒模型。然后,采用数学推演和对偶理论将原问题转化为混合整数二阶锥双层模型,并利用二分法结合商业求解器GUROBI进行迭代求解。最后,通过修改的IEEE 33节点系统验证所提模型的有效性。

Abstract

This paper tackles the complexities of benefit allocation among diverse stakeholders and layered uncertainties in collaborative operations, by proposing a dynamic pricing based bilevel distributionally robust scheduling approach for enhanced control over energy in multi-microgrid active distribution networks. At the outset, it addresses the challenge of equitable benefit allocation between active distribution network and multiple microgrids through a dynamic pricing mechanism sensitive to branch losses and energy-load distribution patterns. A structured bilevel model emerges, where the active distribution network determines transaction prices for microgrids through this pricing mechanism, while microgrids respond by adjusting their load schedules according to their demand requirements. Moreover, the influence of main grid price fluctuations and renewable energy production variability is encapsulated within a resilient bilevel distributed model. Through the application of mathematical deduction and duality theory, the original problem is reformulated into a mixed-integer second-order bi-level cone bilevel model, solved iteratively using a bisection method combined with the GUROBI solver. The practical efficacy of the proposed framework is demonstrated through the adaptation of the modified IEEE 33-node system.
