Educational Simulator of Smart Grid (ESSG)

This paper presents a new power system analysis tool named the Educational Simulator of Smart Grids (ESSG/SESG in French) for isolated, connected, and interconnected nanogrid and microgrid systems. The ESSG is a simulation tool launched through a Matlab application. It is based on theoretical concepts, enabling the modeling of various systems and the implementation of management and optimization techniques for different renewable energy system topologies. The simulations are performed using MATLAB software, where models are developed and simulated. Furthermore, a developed manager is offered to enhance the value of the ESSG application in terms of the software, incorporating the creation of a 3D environment. As a result, the observation and management interface will serve as a link between these two aspects. This work focuses on the optimal management and load balancing of nanogrids connected to Electric Vehicle (EV) stations, and all the results are integrated into the ESSG simulation tool. The overall graphical interface that was developed within the ESSG application was introduce in this paper. In addition, a microgrid system was integrated into the ESSG simulator to visualize and analyze the dynamic behavior of frequency and power transfer for an isolated and interconnected system with hybrid storage. This work was based on two topologies: isolated and interconnected.
