Enhancing Control in Microgrids with Simulink and OPC: A Methodology to Boost Researchers’ and Students’ Skills

A method for transferring control strategies designed in MATLAB/Simulink environment into an actual SCADA systems through OPC communication is presented in this paper. The primary focus is on the regulation of a microgrid, overseen by a SCADA system, using MATLAB/Simulink. The OPC protocol facilitates the connection between the simulation software and the SCADA system, streamlining the process for researchers and students by eliminating the reliance on conventional devices, such as PLCs, thereby enhancing operational flexibility. This methodology is particularly advantageous for students, enabling them to gain practical experience in managing microgrids and energy systems through advanced software tools, without the complexities of traditional hardware programming. The experimental test considers the management of a cogenerator within the PrInCE Lab microgrid at the Polytechnic University of Bari, with the aim of balancing electrical demand and eliminating dependence on the external grid. The paper details the development of the MATLAB code and the configuration of control systems within Simulink, facilitating communication with the SCADA system via OPC protocol. Results are provided on how students can collaborate and compete with each other, showing how the proposed methodology can provide an effective and educational tool for practical learning.
