基于热泵型储电技术国内外研究综述
Summary of research on power storage technology based on heat pump at home and abroad
摘要
Abstract
Under the strategic goal of"double carbon,"renewable energy power generation,including solar and wind energy,has experienced steady growth.However,the existing technology faces challenges in supporting the increasing consumption of renewable energy,necessitating large-scale energy storage devices to ensure the stable operation of the power grid.Pumped thermal energy storage(PTES)technology is a promising solution,offering high efficiency,high energy storage density,and flexible on-demand construction.Compared to other large-scale energy storage technologies under development,PTES demonstrates superior research value and application prospects.This paper begins outlining the working principle of PTES and categorizes it into power storage systems based on the Brayton cycle(three types)and systems based on the Rankine cycle.A comparison and summary of the technical characteristics of these two systems are provided.While the Brayton cycle-based system faces challenges related to high heat storage temperatures,the Rankine cycle-based system effectively reduces heat storage temperatures but introduces issues with high system pressure.Subsequently,the research status of the core components of PTES is outlined,along with the influence of storage tank arrangement and energy storage medium type on system efficiency.Comprehensive analysis reveals that current heat pump power storage technology research primarily focuses on the power storage system's process design and thermodynamic optimization analysis.PTES holds promise in power storage and exhibits potential in waste heat recovery and cogeneration.Establishing a multi-energy complementary system utilizing low-grade waste heat in various production and life scenarios can enhance PTES's efficiency in electricity,heat,and cold regulation and management within the energy system.This approach is anticipated to expedite the transition of China's energy system toward greener and lower carbon emissions.关键词
