Abstract

Microgrids are playing an ever-growing role in the conceptual evolution of the traditional electrical system into a more modern and decentralized grid. The greatest advantage enabled by microgrid is the integration of different technologies, such as: distributed renewables (solar, wind, hydrogen, biogas), energy storage (batteries, flywheels), demand management (energy efficiency, demand response), smart measuring, electrical vehicles, advanced communications systems, optimization of distributed resources, among others. Microgrids emerge with the main objective of coordinating and merging different technologies (with different levels of technical and commercial maturity) in a single platform. It is in this context that this research project is built, with the goal of developing a mathematical model of mixed-integer linear programming (MILP) for both the project and microgrid dimensioning, considering the array of available technologies of distributed energy resources and the technical and strategic definitions of the energy concessionaire. A MILP model has the following benefits: (a) a robust, generic and flexible mathematical model; (b) an efficient computational solution with conventional solvers; (c) the convergence to the optimal solution is guaranteed utilizing classical optimization techniques. The MILP model will be applied using the mathematical modeling language AMPL and using the commercial solver CPLEX.
