A microgrid currently under construction in Venice, Italy, is part of a plant for testing quasi-zero-emission processes. It has a 400-V ac bus and works islanded and connected. It includes three renewable-source generators and five energy storage (ES) systems (ESSs), based on lithium (Li), lead (Pb), sodium (Na), vanadium, and hydrogen. The hierarchical control uses a master system (Li battery) and slave systems. An energy management system (EMS) with a supervisory-control-and-data-acquisition-like architecture controls the microgrid, providing such features as anti-islanding, lowvoltage ride through, and black start. The EMS performs acquisition, processing, and storage of the data produced by power network analyzers. An advanced human interface ensures flexible operation management and performance analyses. This article presents the design of this multitechnology microgrid, which is part of an industrial pilot plant aimed at promoting a number of decarbonized technologies.

威尼斯真正的多技术微电网：设计回顾

目前正在意大利威尼斯建设的微电网是用于测试准零排放过程的工厂的一部分。它有一个 400-V 交流总线，并以孤岛和连接方式工作。它包括三个可再生能源发电机和五个基于锂 (Li)、铅 (Pb)、钠 (Na)、钒和氢的储能 (ES) 系统 (ESS)。分级控制使用主系统（锂电池）和从系统。具有类似监督控制和数据采集架构的能源管理系统 (EMS) 控制微电网，提供抗孤岛、低电压穿越和黑启动等功能。EMS 对电力网络分析仪产生的数据进行采集、处理和存储。先进的人机界面确保灵活的操作管理和性能分析。
