Fully Distributed Secondary Voltage Control in Inverter-Based Microgrids
For microgrid operators, this work reduces communication dependency in voltage control, but the improvement is incremental over existing distributed methods.
The paper proposes a fully distributed secondary voltage control for inverter-based microgrids, eliminating the need for system-wide communication. Simulation on a 6-DG case study demonstrates its effectiveness.
Centralized secondary voltage control in a power system has been replaced by the distributed controller in the recent literature due to its high dependency on extensive communication messages. Although in the new method each distributed generator only communicate with its neighbors to control the voltage, yet the messages are circulating among the whole system. In this paper, we have utilized distributed controller locally so that it will work as a fully distributed control system. This controller has been justified by being studied within a case study including 6 distributed generators.
