科技日报：湖北首个变电站内储能项目在武汉投运

Group 1 - The core viewpoint of the news is that a new energy storage project in Wuhan is operational, which helps alleviate the pressure on the power grid during peak electricity usage periods due to high temperatures [1][3] - The energy storage project, located at the 110 kV Baoan Substation, has a total capacity of 10,000 kVA and can output up to 20,000 kWh to the main grid during peak times, effectively reducing the load on the substation's main transformer by 10% [3] - The project has successfully completed four safe charge and discharge cycles, delivering a total of 80,000 kWh of electricity, thereby ensuring reliable power supply during peak load periods [3] Group 2 - The construction of the energy storage project faced various challenges, including tight construction schedules, adverse weather conditions, and strict nighttime work regulations, but the company employed strategies like pre-installed foundations and cross-operation to ensure timely completion [3] - The new energy storage system is described as a "virtual generator," which actively participates in grid regulation by simulating synchronous generator characteristics, thus providing voltage, frequency, and inertia support to maintain system stability more effectively [4]
