Energy Management Electronic Device for Islanded Microgrids Based on Renewable Energy Sources and Battery-based Energy Storage

Abstract

Energy management systems are one of the most important components in the operation of an electric microgrid. They are responsible for ensuring the supervision of the electrical system, as well as the coordination and reliability of all loads and distributed energy resources in order for the microgrid to be operated as a unified entity. Because of that, an energy management system should be fast enough at processing data and defining control action to guarantee the correct performance of the microgrid. This paper explores the design and implementation of an energy management system deployed over a dedicated electronic device. The proposed energy management device coordinates the distributed energy resources and loads in a residential-scale islanded microgrid, in accordance with a rule-based energy management strategy that ensures reliable and safe operation of the battery-based energy storage system. A hardware-int-he-loop test was performed with a real-time simulation platform to show the operation of the electronic device

Design and Control of a Photovoltaic Distribution System Based on Modular Buck-Boost Converters

“…However, the massive implementation of NCRES constitutes drawbacks for operating electrical power systems according to their power and distribution levels, given the randomness of these primary resources. For a massive expansion of these distributed energy resources (DERs), it is essential to develop novel control functionalities that mitigate the large-scale impacts of these technologies Luna et al (2020). In Hern ández et al (2021, an islanded microgrid for a rural area was designed and simulated in PSCAD/EMTDC.…”
