Scenario analysis for smart microgrids towards a holistic decarbonization of energy systems by using local energy sources

This paper presents a technical-economic analysis of a microgrid system that incorporates distributed energy resources (DER) such as a photovoltaic (PV) system, battery energy storage system (BESS) and emergency generator, aimed at providing energy reliability and cost optimization in islanded or difficult-to-access areas such as the proximity of the Danube Delta from Romania. The study is centered on peak shaving, load shifting and battery management strategies enabled by BESS, which are essential for reducing energy costs during peak demand and optimizing energy usage by storing excess renewable energy and its utilization during high-demand periods and considering large market energy prices, that can vary. In other to better study the interactions between the different energy management strategies a microgrid system consisting of a renewable energy source, an energy community, a generator and BESS system was simulated using a number of possible scenarios.The analysis highlights the benefits of BESS in managing renewable energy variability, stabilizing grid frequency, and improving system resilience. Furthermore, the paper presents how software tools like Ignition, Grafana, and MariaDB are used together to monitor and manage data flow within the microgrid system, this data can be used in order to improve the algorithm.
