微电网“操盘” 泰安领跑工业园区绿色转型

Core Viewpoint - The article highlights the successful implementation of a flexible microgrid system in Tai'an, Shandong, which utilizes solar energy and energy storage to enhance energy efficiency and reduce carbon emissions in industrial parks [1][2]. Group 1: Microgrid Technology - The microgrid system integrates energy routers, flexible interconnection devices, and intelligent control technologies to provide clean and stable power supply [1]. - The system employs direct current (DC) power supply from solar energy, eliminating traditional AC-DC conversion, thus improving safety and efficiency [1]. - The microgrid has achieved a 100% utilization rate of green electricity, saving over 5 million yuan in electricity costs and reducing CO2 emissions by over 9,300 tons annually [1]. Group 2: Collaboration and Innovation - The Tai'an Group collaborates with Tsinghua University to develop energy routers based on third-generation semiconductors, overcoming key technical challenges and achieving international leading standards [1]. - The microgrid system is designed to enhance flexibility and controllability, integrating zero-carbon buildings, medium and low-voltage interconnections, and energy storage solutions [1]. Group 3: Broader Implications and Future Plans - Tai'an City is promoting the expansion of microgrid technology from single-point demonstrations to comprehensive coverage, establishing a technical innovation alliance in the microgrid field [2]. - The city has implemented 21 demonstration projects, with 10 already operational, collectively consuming approximately 26 million kilowatt-hours of green electricity and reducing carbon emissions by about 20,000 tons [2]. - Future plans include building a unique industrial ecosystem combining green equipment manufacturing, green power production, and carbon asset management to support high-quality development of smart microgrids [2].
