Enhancing Renewable Energy Utilization in Microgrids through a Flexible Load Dispatch System

This paper proposes a High-Efficiency Flexible Load Microgrid System (FLMS) designed to improve renewable energy utilization in microgrids through optimal economic dispatch. By integrating a Clever Power Distributor (CPD), the system effectively schedules inputs from various renewable sources, converting their long-term instability into short-term stability. This enables direct allocation of energy to loads using load classification and dynamic distribution methods, improving direct renewable energy usage and reducing electricity costs. The FLMS economic model combines renewable generation, energy storage, and grid electricity into an optimized framework guided by intelligent algorithms and Lagrangian analysis. Simulation results across 12 industries and four seasons in Shanghai show that FLMS achieves 37.5% to 57.7% higher renewable energy utilization rates compared to traditional microgrids. These improvements enhance energy independence, reduce carbon emissions, and lower operational costs, contributing to the realization of a green and economically efficient source-grid-load-storage integration.
