【榆林】西北首个兆瓦级飞轮储能调频示范项目并网投运

Core Viewpoint - The successful commissioning of the first megawatt-level flywheel energy storage project in Northwest China marks a significant advancement in energy storage technology, enhancing grid stability and supporting the transition to renewable energy sources [1][2]. Group 1: Project Overview - The flywheel energy storage project, led by Yulin Energy Yanghuopan Coal Power Company, has a total capacity of 8 megawatts and 0.32 megawatt-hours, consisting of eight flywheel storage units, each with a capacity of 1 megawatt and 0.04 megawatt-hours [1]. - The project utilizes high-speed rotating flywheels for efficient conversion between electrical and kinetic energy, offering advantages such as millisecond-level response, high regulation precision, long cycle life, and environmental friendliness [1]. Group 2: Industry Significance - Energy storage is identified as the "ballast" of the new power system and is crucial for achieving carbon neutrality goals, with Yulin being a major energy city requiring both large-capacity and fast-response energy storage solutions [1]. - The project addresses the integration control challenges between flywheel storage systems and large-capacity coal power units, enhancing operational flexibility and reliability of power supply, thereby facilitating the absorption of more intermittent renewable energy [1]. Group 3: Demonstration and Impact - The project represents a substantial breakthrough in innovating traditional frequency regulation methods and enhancing grid safety and stability, holding significant industry demonstration value and potential for broader application in supporting the stable operation and clean transition of the Northwest power grid [1].
