This project addresses the necessity of transforming electrical distribution substations from local, limited systems into active, global, and automated systems capable of responding to the dynamics of the modern grid (Smart Grids). The central problem lies in the increasing complexity of distribution systems due to the integration of new energy sources (distributed generation, electric vehicles) and the need to improve efficiency, power quality, and reduce outages. The proposed solution focuses on identifying and evaluating the optimal control and operation model for these substations, adhering to international standards like IEC 61850. The methodology includes a state-of-the-art review of existing models, the collection and simulation of data from a distribution circuit (including loads, voltages, and distributed generation) using specialized software, and the creation of a database. Subsequently, comparative testing and analysis of the control and operation models will be performed via simulation, assessing their sensitivity and accuracy when implementing distributed automation through Intelligent Electronic Devices (IEDs) and centralized protection and control systems (CPC). The ultimate goal is to establish a model that enhances the reliability, security, and operational functionality of the substation.<br/><br/><b>Goal</b>: <br/>To determine the optimal model for the control and operation of electrical distribution substations, utilizing automation techniques in power electrical systems.<br/><br/><b>Research lines</b>: <br/>Optimization in electrical systems
