摘要
随着风电、光伏等可再生能源大量接入,主动配电网源荷不确定性显著增加,系统运行面临新的挑战。提出一种考虑多资源协调的结构-柔性层次鲁棒优化模型,联合调度储能、静止无功补偿装置(static var compensator,SVC)、电容器组(capacitor bank,CB)及需求响应等多类资源,该模型采用“先结构、后柔性”的分层优化思路,先确定储能启停和CB投切等结构性方案,构建系统运行基础,再动态调节SVC出力、储能功率、需求响应及主网购电等柔性资源,实现结构性决策与柔性资源的融合。提升系统对源荷波动的适应能力,用区间预算约束集对源荷不确定性建模,保证调度方案的鲁棒性。在IEEE 33节点系统上的仿真分析表明,该方法能够有效减少结构性操作频率,提高了柔性资源调度的能力,在不确定性条件下提升主动配电网运行的经济性与安全性。
Abstract
With the increasing integration of wind and photovoltaic energy, source-load uncertainties in active distribution networks have posed new operational challenges. A coordinated multi-resource scheduling approach was proposed, considering energy storage, static var compensator (SVC), capacitor bank (CB), and demand response. A “structure-first, flexibility-second” decision-making framework was adopted. Under this framework, structural decisions such as energy storage commitment and CB switching were first determined to establish a robust system foundation. Then, flexible resources were dynamically adjusted to respond to real-time fluctuations. Uncertainties were modeled using interval and budget constraints to ensure solution robustness. Simulation results on the IEEE 33-bus system show that the proposed method reduces the frequency of structural operations, enhances multi-resource coordination, and improves both economic performance and operational security under uncertainty.

近年来,针对配电网源荷不确定性问题,鲁棒优化方法得到广泛关注。文献[4]提出基于高斯混合模型的光伏自适应鲁棒调度策略,结合仿射决策规则降低运行成本。文献[5]通过列与约束生成(column and constraint generation,C&CG)鲁棒优化算法提高系统的灵活性容量。在配电网中配置储能系统可以有效缓解风光接入对配电网产生的影响,文献[6]通过混合储能优化与储能配置提升配电网经济性与效率。文献[7]针对风光不确定性,提出一种配电网储能优化配置方法,有效改善了系统电压质量。静止无功补偿器(static var compensator,SVC)与电容器组(capacitor bank,CB)等无功调节手段有助于电压稳定与损耗降低,文献[8]进一步从多周期与多层协调角度优化无功控制。需求侧响应(demand response,DR)作为柔性负荷资源,能有效提升系统可调性与经济性,文献[9]考虑分布式电源(distributed generation,DG)出力波动性和需求响应提出配电网双层优化调度模型,提高配电网的电压质量和风光的消纳水平。文献[10]结合储能与需求响应提出多目标鲁棒优化与日前调度模型,应用C&CG算法提高可再生能源消纳能力。
