用于火储联合调频的多元混合储能系统应用及经济性分析
Application and Economic Analysis of Multi-element Hybrid Energy Storage System Joint With Thermal Power Units for Frequency Regulation
摘要
Abstract
Due to the influence of steam to electricity conversion characteristics,traditional thermal power units have low accuracy in active power regulation and slow response rates.By properly configuring the energy storage system in conjunction with frequency regulation of thermal power units,mechanical damage caused by frequency regulation can be reduced,better meeting the frequency regulation needs of new power systems dominated by new energy.An analysis was conducted on the frequency regulation requirements of the new power system,and the characteristics of a multi-component hybrid energy storage system composed of lithium-ion battery energy storage system and flywheel energy storage system were studied.By utilizing the characteristics of large capacity of lithium-ion batteries,long frequency regulation mileage,faster response speed,large regulation power,and long service life of flywheel energy storage system,the advantages of the two energy storage technologies were complemented through reasonable wiring design and intelligent coordinated control strategy.Through case analysis,the principles of capacity configuration,wiring types,and control strategies of energy storage systems were introduced,and the benefits calculation and technical and economic analysis were carried out to verify the feasibility of the technical scheme and economic efficiency of the multi element hybrid energy storage system.关键词
