Abstract
This work presents the modeling and simulation of the economic dispatch performed in a microgrid. A flexible algorithm is developed in order to get the optimal operation of a microgrid. The performed simulations use the load and generation profiles from an operative real microgrid. Due to this, the results are similar to the real operation of a microgrid. The performed simulations consider two types of topologies: a one node microgrid and radial multi-node microgrid. The battery storage model considers the efficiency coefficients for the charging and discharging and the auto-discharging coefficient. The multi-node model includes the maximum power flow constraints for the distribution lines, the formulation includes the estimation of power losses using DC power flow. The DC Power Flow is used to estimate the power losses in a multi-node microgrid, the results are compared with an AC Power flow. The economic dispatch is formulated as a mixed integer linear programming optimization problem.
