Optimal Operation of Hybrid AC/DC Microgrid Including PV/WT/ES Considering Battery Charging and Discharging Times Constraint

Abstract

Distributed generations have obvious features, including flexibility, randomness, intermittence and uncertainty. Energy storage can be equiped with such power supply, which can improve the new energy consumptive rate and ensure the reliability of power supply. The service life of the battery is mainly affected by its discharge depth, charge and discharge times and other factors. In this paper, the battery state of charge constraints, charge and discharge times constraint are taken into account, so as to decrease the battery charging and discharging frequency. Through an actual example, artificial bee colony is used to solve the objective function of the minimum operation cost of hybrid AC/DC microgrid including PV/WT/ES.
