Abstract
En 中文
The insertion of microgrids brings new challenges for power grid operation. In this regard, a digital twin for the Barigui microgrid in Curitiba, Brazil, was developed up to the point of connection to the main grid using the HYPERSIM tool from OPAL-RT Technologies for simulating electrical systems in real time. This microgrid is composed of a 39kW photovoltaic system, a carport with 3kW of photovoltaic solar generation and a 7kW electric vehicle charger, in addition to a 28kWh storage system with lithium-ion batteries, and controllable and non-controllable loads. Furthermore, different operating scenarios for the microgrid were considered, as well as the emulation of communication with the SCADA of the distribution power utility. One of the main advantages in obtaining the digital twin of the grid, or part of it, is being able to know the behavior and responses of the circuit at the same time in which the real system would respond, thus allowing the evaluation of scenarios that in the field could lead to damage to equipment and damage to network operation. Having this knowledge previously grants greater decision-making power to the distributor, contributing to improving the quality and continuity of the service.
