论文摘要
本文提出了一个能源管理系统（EMS），该系统考虑了一组互连的微电网（MG）和主电网之间的功率交换，并在Multi-MG（MMG）系统的背景下进行。该模型首先是作为集中优化问题配制的，然后使用拉格朗日放松将其分解为对应于每个MG的子问题，并使用亚级别方法通过分布式方法解决。拟议的模型确定了电力交换最小化每个毫克的运行成本，考虑到网格限制，并通过不揭示其产生的成本和需求信息来保留每个MG的隐私。关于集中式问题的分布式方法得到了验证，并提出了各种案例研究，以证明拟议方法的性能，并比较了单独和合作运行的MGS的成本。结果表明，MMG系统中的所有MGS都会由于功率交换而提高其成本，从而证明了互连MG的优势。
This paper presents an Energy Management System (EMS) that considers power exchanges between a set of interconnected microgrids (MGs) and the main grid, in the context of Multi-MG (MMG) systems. The model is first formulated as a centralized optimization problem, which is then decomposed into subproblems corresponding to each MG, using Lagrangian relaxation, and solved through a distributed approach using a subgradient method. The proposed model determines the power exchanges minimizing the operation cost of each MG, considering grid constraints and preserving the privacy of each MG by not revealing their generation cost and demand information. The distributed approach is validated with respect to the centralized problem, and various case studies are presented to demonstrate the performance of the proposed approach, comparing the costs of the MGs operating individually and cooperatively. The results show that all MGs in the MMG system improve their cost as consequence of the power exchanges, thus demonstrating the advantages of interconnecting MGs.
