High Bandwidth Distributed Secondary Control with Communication Compensation in VSC-based Microgrid

This paper proposes a novel wireless-based robust communication approach for the high bandwidth distributed secondary control in parallel operation of voltage source converters (VSCs). This approach is realized by firstly applying finite control set model predictive control at primary control level, hence, secondary control can be operated in higher bandwidth. Then, a data prediction block is added to secondary control level to compensate for communication deficiencies. Simulation and experimental results show transient response and the robustness of the proposed approach is far superior to conventional algorithms.
