Abstract
This plan outlines an energy scheduling strategy for a distribution grid with multi-microgrid systems, based on the assessment of economic and operational indicators within the microgrids. The microgrid operates on a multi-bus structure, incorporating renewable sources like solar and wind alongside non-renewable resources and hydrogen storage systems. The primary objective is to minimize the operational costs of microgrids and associated resources. The problem is subject to various constraints, including the optimal power flow formulation for the microgrids, performance models of renewable and non-renewable units, and the dynamics of storage devices. Due to the non-convex and nonlinear nature of the formulation, a honey-bee mating optimization method is employed to ensure a reliable solution with minimal deviation toward the final result. The findings demonstrate the plan’s potential to enhance both the technical and economic performance of microgrids. Specifically, energy scheduling for the included units and storage systems can improve operational efficiency by approximately 59.2% and economic conditions by about 44.2%. Furthermore, the proposed solution approach achieves sustainable computing conditions by delivering near-optimal solutions with low computational time and a standard deviation of just 0.97% in the final results.
