Proposal for the optimal management of a DC microgrid
Descargas
This paper addresses the management of power resources in isolated microgrids employing renewable energy. Based on a simple Newton-Raphson algorithm programmed and incorporated into numerical simulations of the system equivalent circuits, the power sharing among generators of a DC microgrid has been performed. The proposed approach defines cost functions weighting the contribution of renewable sources supplying a given power demand by means of a hierarchical structure of droop control driving internal loops of PI controllers regulating dynamics of boost power converters. Simulation results show the adaptability to environmental changes of the amount of power generated, unveiling an interesting feature needed in the real operation of microgrids. Ongoing work is focused on experimental validation of the proposed method in a real laboratory prototype.
