Why This Matters

Microgrids require sophisticated distributed control algorithms to maintain stability during transitions between grid-connected and islanded operation, but implementing these algorithms across distributed hardware remains challenging. This work is significant because it demonstrates that the RIAPS platform can reliably execute hierarchical microgrid control with sub-second synchronization accuracy and distributed decision-making, validating the platform for critical grid applications.

What We Did

This paper describes implementation of a distributed microgrid controller on the RIAPS platform that achieves voltage frequency regulation and resynchronization of islanded microgrids. The work presents detailed algorithms for primary droop control, secondary frequency and voltage regulation, and resynchronization procedures using distributed messaging. The implementation demonstrates deployment of complex control algorithms across distributed nodes using the RIAPS middleware.

Key Results

The RIAPS-based controller successfully maintained voltage and frequency stability during intentional islanding events with distributed secondary control responding to frequency deviations. Resynchronization procedures safely reconnected the microgrid to the main grid without instability. Real-time measurements confirmed voltage phase accuracy within specification and effective distributed coordination of multiple generator controllers.

  abstract = {Formation of microgrids have been proposed as a solution to improve grid reliability, and enable smoother integration of renewables into the grid. Microgrids are sections of the grid that can operate in isolation from the main power system. Maintaining power balance within an islanded microgrid is a challenging task, due to the low system inertia, which requires complex control to maintain stable and optimized operation. Many studies have demonstrated feasible distributed microgrid controllers that can maintain microgrid stability in grid connected and islanded modes. However, there is little emphasis on how to implement these distributed algorithms on a computational platform that allows for fast and seamless deployment. This paper introduces a decentralized software platform called Resilient Information Architecture Platform for Smart Systems (RIAPS) that runs on processors embedded with the microgrid component. As an example, we describe the implementation of a distributed microgrid secondary control and resynchronization algorithms on RIAPS platform. The controller developed on RIAPS platform is validated on a real-time microgrid testbed.},
