Islanded microgrids require distributed control to maintain frequency and voltage without a centralized authority. Traditional centralized control is infeasible when the grid separates from the main system. This paper addresses the challenge by developing distributed control strategies that coordinate generators using local measurements and sparse communication.
This paper presents a distributed microGrid synchronization control strategy using the RIAPS platform. The work proposes frequency and voltage regulation controllers that coordinate distributed generators through sparse communication networks and demonstrates implementation on practical hardware with real-time execution.
The paper demonstrates successful implementation of distributed frequency/voltage regulation on RIAPS platform with real-time execution. Results show synchronization and proportional active power sharing among generators with millisecond-level control actions. The work validates distributed control through both simulation and hardware-in-the-loop testing.

abstract = {To seamlessly reconnect an islanded microgrid to the main grid, voltage phasors on both sides of the point of common coupling need to be synchronized before the main relay closes. In this paper, a distributed control strategy is proposed for microgrid synchronization operation. The proposed controller design utilizes pinning-based consensus algorithm to avoid system single point of failure. It is able to actively track the main grid frequency, provide a good coordination between frequency and phase regulation and ensure all distributed generations in the system proportionally share the load. Implementation of such distributed algorithm in practice is difficult because it requires mitigation of both distributed computing and power system engineering challenges. In this paper, a novel software platform called RIAPS platform is presented that helps implementing the proposed distributed synchronization strategy in practical hardware controllers. The performance of the controllers are validated using a real-time controller hardware-in-the-loop microgrid testbed.},
