This study focused on optimizing the performance of energy microgrids, factoring in economic and environmental metrics for day-ahead planning. The proposed microgrid features a combination of hybrid energy resources, which include power, heat, and hydrogen systems. . The interplay between energy, social sustainability, and the economic and environmental dimensions has prompted energy operators to explore various challenges associated with energy operations. In the upper optimization model, the wind–solar–storage capacity optimization model is. . A microgrid is a promising small-scale power generation and distribution system. The selling prices of wind turbine equipment (WT), photovoltaic generation equipment (PV), and battery energy storage equipment (BES) have a significant impact on microgrid profits, which, in turn, affects the planning. .

During the past year, solar and battery storage have dominated capacity additions, coupled with a strong showing by wind: Between January 1 and October 31, 2025, utility-scale solar capacity grew by 19,477. 6 MW while an additional 4,837. 7 MW was provided by small-scale. . Moreover, utility-scale solar thermal and photovoltaic expanded by 34. 5% while that from small-scale systems rose by 11. 3% during the first ten months of 2025 compared to the same period in 2024. 1%) and produced. . 82% of U. energy comes from fossil fuels, 8. 7% from nuclear, and 9. In 2023, renewables surpassed coal in energy generation. 1 Global wind additions reached a record 117 GW in 2023, totaling 1,021 GW. remained the second-leading market in annual and cumulative. .
