Power system configuration and performance are changing very quickly. Under the new paradigm of prosumers and energy communities, grids are increasingly influenced by microgeneration systems connected in both low and medium voltage. In addition, these facilities provide little or no information to distribution and/or transmission system operators, increasing power system management problems. Actually, information is a great asset to manage this new situation. The arrival of affordable and open Internet of Things (IoT) technologies is a remarkable opportunity to overcome these inconveniences allowing for the exchange of information about these plants. In this paper, we propose a monitoring solution applicable to photovoltaic self-consumption or any other microgeneration installation, covering the installations of the so-called 'prosumers' and aiming to provide a tool for local self-consumption monitoring. A detailed description of the proposed system at the hardware level is provided, and extended information on the communication characteristics and data packets is also included. Results of different field test campaigns carried out in real PV self-consumption installations connected to the grid are described and analyzed. It can be affirmed that the proposed solution provides outstanding results in reliability and accuracy, being a popular solution for those who cannot afford professional monitoring platforms.
电力系统的配置和性能变化非常快。在新的产销者和能源社区范式下,电网越来越受到连接在低、中压的微电网系统的影响。此外,这些设施几乎没有或根本没有向配电和/或输电系统运营商提供信息,增加了电力系统管理的问题。实际上,信息是管理这种新形势的宝贵资产。价格合理且开放的物联网 (IoT) 技术的到来是一个很好的机会,可以克服这些不便,实现有关这些工厂的信息交换。在本文中,我们提出了一种适用于光伏自消费或任何其他微电网装置的监控解决方案,涵盖了所谓“产销者”的装置,并旨在提供一种用于本地自消费监控的工具。详细描述了硬件级别的建议系统,并包含有关通信特性和数据包的扩展信息。描述并分析了在实际连接到电网的光伏自消费装置中进行的不同现场测试活动的结果。可以肯定的是,所提出的解决方案在可靠性和准确性方面提供了出色的结果,是那些无法承担专业监控平台的人的流行解决方案。
