锂电+超级电容混合储能！陕西首台（套）火储调频项目在铜川投运

Core Viewpoint - The successful operation of the first fire-storage frequency modulation project in Shaanxi Province marks a significant step in integrating flexible transformation of thermal power and new energy storage technologies [1][3]. Group 1: Project Overview - The project, built by Shaanxi Comprehensive Energy Group and Huaneng Tongchuan Zhaojin Coal Power Co., features a mixed energy storage system composed of a 15MW/15MWh lithium iron phosphate battery and a 5MW/6min supercapacitor [1]. - This demonstration project represents a key advancement in the application of new energy storage technologies in the region [1]. Group 2: Technical Advancements - Traditional thermal power units face challenges such as slow response times (in minutes), low adjustment precision, and high return delays, which hinder their ability to effectively manage the volatility brought by large-scale integration of renewable energy [3]. - The project enables deep coupling of thermal power and energy storage, utilizing high-rate power storage cells that provide millisecond-level response speed, ±0.01Hz adjustment precision, and over 10,000 cycles of lifespan [3]. - After commissioning, the frequency modulation response speed of the power plant is expected to improve to seconds, with adjustment errors reduced by over 80%, significantly lowering grid frequency deviations [3]. Group 3: Performance Metrics - The K-value of thermal power unit frequency modulation performance indicators is projected to increase by more than two times, effectively addressing issues related to long response times and low ramp-up rates of thermal power units [3].
