A Reliable Graph-Based Routing Algorithm in Residential Multi-Microgrid Systems

Abstract

With recent technology breakthroughs, employing a power router as a gateway to attach microgrids with a power system is being increasingly important for regulating bidirectional data and power flow. The energy routing algorithm strategy is one of the most critical factors in assessing the performance of a multi-microgrid system, however, existing power routing algorithms have certain limitations. A crucial limitation is the reliable dispatch of power transmission among the microgrids. None of the existing algorithms carry forward the power loss during the transmission. In this article, we introduce optimizations in an existing algorithm to minimize the overall power losses incurred during the transmission process. Therefore, by minimizing the power losses, we shall be able to meet the amount of power delivered to a microgrid, making our system more reliable. The performance of the proposed algorithm has been validated in different scenarios. To visualize the novelty of the proposed algorithm, its results are compared with existing methods in terms of congestion management, power losses, reliability, accuracy, and handling diverse situations, to name a few. We expect our idea would inspire others to introduce novel optimizations in various processes of multi-microgrid systems.
