An adaptive control of hybrid battery-supercapacitor storage for integration of wind and solar

Abstract

Integration of wind and solar within dc microgrids into buildings is presented. First, a cache control method is applied to utilize a hybrid energy storage which combines diverse but complementary storage technologies. Second, an adaptive droop scheme is proposed to provide coordination control of a battery in real-time and long-term operation. Compared with other existing droop controls, it is distinguished in that the adaptive droop is proposed to force real-time state of charge of battery to track on the optimized scheduled SOC in long-term. Several simulations are performed to realize the presented method.
