基于PowerWord的储能在主动配电网中的仿真研究
摘要
主动配电网是智能配电网技术发展的高级阶段，分布式储能是主动配电网的重要组成部分，分布式储能的应用对主动配电网的规划、运行、网络拓扑、故障处理和保护、可再生能源电源的协调优化等方面带来不容忽视的影响，针对这一现状，本文提出了储能在主动配电网中的仿真研究，并以此为基础对研究了基于PowerWord的储能在主动配电网中的仿真研究方法。
由于储能电池成本高、使用寿命相对较短，因此需要研究了目前储能技术的发展及数学模型。对不同储能技术运行特性进行梳理总结的基础上明确了储能对于主动配电网的关键作用，重点从控制策略与规划配置两个方面对储能在配电网中的研究现状进行了评述并指出了后续研究应进一步关注的问题；本文还探讨了储能的数学模型和经济性分析模型，重点分析了将储能应用于主动配电网中的可行性。

Abstract
Active power distribution network is the advanced stage of intelligent distribution network technology development, distributed energy storage is an important component of the active power distribution network, the application of the distributed energy storage on the active power distribution network planning, operation, network topology, fault handling, and protection, renewable energy power coordinated optimization of nots allow to ignore effects, aimed at the status quo, In this paper, the simulation research of energy storage in active distribution network is proposed, and based on this, the simulation research method of energy storage in active distribution network based on PowerWord is studied.
Due to the high cost and relatively short service life of energy storage batteries, it is necessary to study the development and mathematical model of current energy storage technology. On the basis of summarizing the operation characteristics of different energy storage technologies, the key role of energy storage in active distribution network is clarified, and the research status of energy storage in distribution network is reviewed from two aspects of control strategy and planning and configuration, and the problems that should be paid more attention to in future research are pointed out. This paper also discusses the mathematical model and economic analysis model of energy storage, focusing on the feasibility of using energy storage in active distribution network.
