The work will describe the design and implementation of a computational platform for power flows models in real time with the integration of smart metering, real time monitoring and an information management system. This platform designed within the National Laboratory of Smart Grids of Universidad Nacional de Colombia – “LAB+i” allows connecting from any local or remote process, through communication protocols, to a system of information management in order to involve the measurements obtained in real time to a power flow model of a distribution system. A scenario of large-scale insertion of photovoltaic generation for self-supply of electricity to the university campus is proposed. Real-time monitoring of this system and its integration with the platform is presented, alongside with load profiles substation where measurements are linked in real time. This case study shows the results of load flow in real-time of the National University of Colombia distribution power network with the integration of real-time measurements of a photovoltaic generation system.
