Propuesta de un modelo de planificación óptima de redes inteligentes (Smart Grids) incluyendo integración eficiente de recursos energéticos distribuidos (DER), aplicada a una red de distribución de la CENTROSUR

Abstract

The grid has been overwhelmed with extreme weather events occurring with increasing frequency, with the only practical solution being to de-energize lines and interrupt power supply to many customers. Recent advances in the distribution grid, including the integration of Distributed Energy Resources (DER) and Microgrids, provides potential means to improve the operational resilience of the grid. For this reason, in this thesis it was proposed to develop an Electric Distribution Planning Methodology considering the efficient integration of Distributed Energy Resources (DER), especially related to Charging Stations for Electric Vehicles, Induction Stoves and Distributed Generation. It was supported by Stochastic Models, Optimization Techniques, Geographic Information Systems, and Technical Analysis Systems, in order to optimize the investment and perform an adequate operation of the electric grid. In this new expansion planning, a long-term time frame was defined with a projected number of electric vehicles, which was divided by means of scenarios, where the optimal location, capacity and number of Fast Charging Stations and Distributed Generation installed in the feeder's medium voltage were obtained, that is, the expansion operation of the Smart Grid was analyzed. This methodology was applied to a test network and then to a use case of the network of Empresa Electrical Regional CENTROSUR, and some alternatives were proposed to evaluate and make the best decision.
