Survey of Capacity Allocation of Microgrid Hybrid Energy Storage System Based on Hydrogen Energy Storage

微电网技术发展日益成熟,储能装置的合理配置是解决分布式电源存在随机性与间歇性等问题的主要方式之一,而良好的微电网复合储能容量优化配置方法可以保证微电网经济可靠运行。近几年兴起的氢储能具有清洁、容量大的优势,且对于“碳中和”、“碳排放”具有重要意义,氢能开发与利用已成为世界上许多国家能源体系中的重要组成部分。储能是构建新能源微电网的基础,但单一储能已经无法满足当前微网快速发展条件下的运行要求,因此混合储能的容量配置是目前研究的重点。本文以包含氢储能的混合储能微电网作为基本结构,介绍微电网各组成部分的数学模型和相关研究,对比氢储能和其他储能;阐述储能容量配置目前的研究现状以及存在的相关问题;对氢储能未来其他研究方向和创新进行展望。

Today,with the development of microgrid technology becoming more and more mature,the rational configuration and application of energy storage device is one of the main ways to solve the problems of randomness and intermittence of distributed generation,and a good optimal allocation method of microgrid composite energy storage capacity can ensure the economic and reliable operation of microgrid.Hydrogen energy storage,which has emerged in recent years,has the advantages of clean and large capacity,and is of great significance for"carbon neutralization"and"carbon emission".Hydrogen energy development and utilization has become an important part of the energy system of many countries in the world.Energy storage is the basis for the construction of new energy microgrid,but single energy storage can not meet the operation requirements under the current rapid development of microgrid.Therefore,the capacity configuration of hybrid energy storage is the focus of research at this stage.Taking the hybrid energy storage microgrid containing hydrogen energy storage as the basic structure,this paper introduces the mathematical model and related research of each component of microgrid,and compares hydrogen energy storage with other energy storage;The current research status and existing problems of energy storage capacity allocation are described;Other research directions and innovations of hydrogen energy storage in the future are analyzed and prospected.
