This study deals with the urban microgrid energy management that is dedicated to individual and collective self-consumption by providing flexibility to the distribution grid (DG). The proposed urban community microgrid is interconnected to a DG and it consists of an association of centralized storage units (called community energy storage system), community intermittent renewable generation, and intelligent energy management system (EMS). One of the main advantages of urban microgrid is that, in case of faults in the DG, it can cut existing interconnections and continue to supply the responsible community in the island mode. In this study, the developed urban microgrid EMS is based on the predictive control management through the day-ahead optimal power flow (DA-OPF) strategy. The main contributions of this work can be defined by two points. The first point is related to a development of the DA-OPF strategy for the urban microgrid based on the intelligent deep learning data forecasting and the mixed-integer nonlinear programming optimization methods. The second point concerns a development of an optimization function integrating the concept of ancillary services of DG flexibility. Experimental results and economical evaluation are presented in this article. By using the proposed strategies, it results in an important electricity price reduction for the considered urban microgrid, compared to a conventional distribution system and basic operation schemes.

日前最优潮流用于城市微电网的高效能源管理

本研究通过为配电网（DG）提供灵活性来处理致力于个人和集体自耗的城市微电网能源管理。拟议中的城市社区微电网与DG互连，它由中央存储单元（称为社区能源存储系统），社区间歇性可再生能源发电和智能能源管理系统（EMS）组成。城市微电网的主要优势之一是，如果DG发生故障，它可以切断现有的互连并继续以孤岛模式为负责任的社区供电。在这项研究中，发达的城市微电网EMS基于通过日前最优潮流（DA-OPF）策略进行的预测控制管理。这项工作的主要贡献可以由两点来定义。第一点与基于智能深度学习数据预测和混合整数非线性规划优化方法的城市微电网DA-OPF策略的开发有关。第二点涉及优化功能的开发，该功能集成了DG灵活性的辅助服务的概念。本文介绍了实验结果和经济性评价。与传统的配电系统和基本运营方案相比，通过使用所提出的策略，对于考虑中的城市微电网，它可以显着降低电价。第二点涉及优化功能的开发，该功能集成了DG灵活性的辅助服务的概念。本文介绍了实验结果和经济性评价。与传统的配电系统和基本运营方案相比，通过使用所提出的策略，对于考虑中的城市微电网，它可以显着降低电价。第二点涉及优化功能的开发，该功能集成了DG灵活性的辅助服务的概念。本文介绍了实验结果和经济性评价。与传统的配电系统和基本运营方案相比，通过使用所提出的策略，对于考虑中的城市微电网，它可以显着降低电价。
