Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: May 22, 2025

This study tackles a key challenge in modern energy management: how to optimize distribution when expanding the network is not economically or practically feasible. It explores integration of hybrid renewable sources into microgrid (MG) and proposes an dispatch strategy for MGs operating both grid-connected standalone modes. The incorporates various sources, including solar panels (PV), wind turbines (WT), fuel cells (FC), microturbines (MT), diesel generators (DG), storage systems (ESS). Unlike many existing studies that focus only on reducing costs, this research also considers losses, environmental impacts, demand response-a vital but often overlooked factor. introduces new method using mixed-integer linear programming approach solve management (MGEM) problem. provides multi-objective solution includes response scheduling optimizes factors such as PV WT capacities, strategies, battery usage, power exchange with grid, overall costs impacts. When compared leading optimization algorithms, proposed showed better performance. highlights benefits programs improving MG operations. For instance, Real-Time Pricing (RTP)-based program reduced by 3.31%, emission penalties 2.61%, losses 0.62%. Similarly, Direct Load Control (DLC)-based achieved reductions 2.25%, 2.1%, 3.56%, respectively. work advances addressing demonstrating integrating strategies.
