Application of Consensus Algorithm for Power Dispatch in Autonomous Microgrid

摘要

Microgrid consists of conventional generators, energy storage systems, distributed generators (DGs) such as wind power and photo voltaic (PV) power generation units and their respective control devices. Integration of these DGs with the grid causes technical issues such as voltage and frequency deviations. Microgrid operates in both modes - grid connected as well as islanded mode. But these unwarranted deviations are predominantly observed in the islanded mode wherein the microgrid must maintain its own active power supply-demand balance. In order to minimize these deviations, different control strategies have been implemented. Owing to several disadvantages of different types of centralized control strategies, this work has adopted the distributed control scheme for power dispatch in microgrid that controls the unwarranted deviations in the microgrid network in the islanded mode.
