论文摘要
在设计阶段量化微电网的潜在益处可以支持被动分布网络向微电网的过渡。目前，可靠性和弹性是这种过渡的主要驱动力。因此，本文提出了一个数学优化模型，以支持将分布网络改造成整合技术经济，弹性和可靠性目标的微电网。可以选择安装存储和分布式生成以补充可再生能源的生成，从而使微电网能够在不确定持续时间的随机岛屿事件中提供优先需求。为了全面量化和优化微电网的弹性和可靠性，外部事件引起的岛化与内部故障的详细模型相结合。最小化中断成本可产生最佳能力和分布式能源资源的放置以及重新配置的新线路。提出的方法使用美国能源部的数据，在两个基准分配网络中，具有多达95％的可靠性和弹性增长的微电网设计，并适度的成本增加。由于量身定制的列和约束生成方法，开发的方法可扩展到大型网络。
Quantifying the potential benefits of microgrids in the design phase can support the transition of passive distribution networks into microgrids. At current, reliability and resilience are the main drivers for this transition. Therefore, this paper presents a mathematical optimization model to support the retrofitting of distribution networks into microgrids integrating techno-economic, resilience and reliability objectives. Storage and distributed generation are optionally installed to complement renewable generation, enabling the microgrid to supply priority demands during stochastic islanding events with uncertain duration. For a comprehensive quantification and optimization of microgrid resilience and reliability, islanding due to external events is combined with a detailed model of internal faults. Minimizing the interruption costs yields optimal capacities and placements of distributed energy resources and new lines for reconfiguration. The proposed method produces microgrid designs with up to 95% reliability and resilience gain and moderate cost increase in two benchmark distribution networks using data from the US Department of Energy. The developed methodology is scalable to large networks owing to the tailored Column-and-Constraint-Generation approach.
