用于新能源一次调频的储能经济配置研究
Research on Economic Configuration of Energy Storage for Assisting New Energy in Primary Frequency Regulation
摘要
Abstract
When participating in primary frequency regulation of electrical power systems,it is necessary for new energy to address the issue of energy sources.Configuring energy storage is an effective way.In practical application,the configuration of energy storage needs to consider the factors of physical characteristics,unit cost,and other constraints to comprehensively compare the technical economy.However,the energy storage system configuration schemes proposed in existing literature mainly analyze operational scenarios and fail to consider various engineering constraints and actual cost data of energy storage.Based on the actual cost data,this article fully considers the physical characteristics and engineering design constraints of the energy storage system to study the economy of distributed access to units within the station for assisting primary frequency regulation of new energy.The article analyzes the technical characteristics and design constraints of three types of energy storage systems,namely lithium batteries,flywheels,and supercapacitors.On this basis,three types of configuration methods for energy storage for primary frequency regulation are proposed,and cost analysis and technical economy comparison are conducted based on the configuration schemes.关键词
